Published: June 2021

Seed vigour is an important characteristic of seed quality. Several quantitative trait locus (QTL) has been reported for seed vigour in many crops. In order to validate seed vigour traits, an experiment was conducted with three released rice hybrids and their respective female (A), and restorer/male lines using SSR markers. A total of 18 quantitative traits loci (QTLs) were chosen for seed vigour characters for which 16 SSR markers that were dispersed throughout the 11 chromosomes of rice have been assessed. Eight SSR markers were polymorphic among the genotypes studied. These markers showed distinct bands in female (A), male (R) and hybrid (H). Further, genuineness of all the hybrids under study could be established using the primer RM 252.

Published: June 2021

Commercial exploitation of rice hybrid for sustainable production and productivity largely depends on genetic purity of hybrid seed used. To detect genetic impurity in the hybrid seeds developed through the three-line system using wild abortive (WA) cytoplasmic-based male sterility, a multiplex PCR assay was designed . A total of six primers, namely, DRRM-Rf3-10, Rf4-STS, RM6100, CMS-WA, osWA352 and RMS-3-WA352 were designed based on fertility restorer genes Rf3, Rf4 and Wa352. The primer combinations having RF4-STS and CMS-WA markers of Rf4 and WA352 genes, respectively showed clear and distinct PCR banding patterns among the WA-cytoplasm possessing 31A, fertile restorer PK117 lines and their cognate hybrid rice, Ajay. This multiplex PCR will be useful for assessment of genetic purity of hybrid rice seeds.

Published: June 2021

Stem characters such as stem solidness and stem carbohydrates (water soluble carbohydrates and non-structural carbohydrates estimated as fructan) play an important role in stabilizing grain yield in stressful environments. Ten wheat genotypes were screened for carbohydrate content (Water soluble sugars and fructan) in peduncle along with other stem parameters namely, stem solidness, grain growth rate and stem osmotic potential under irrigated and drought conditions. Data was analyzed for correlation among these parameters along with biomass and yield. The results of present study indicated that stress-tolerant genotype RIL-S1-38 and WH 1235 accumulated higher fructan content in stem and contributed in grain growth rate, reduced osmotic potential and further imparted drought tolerance. Clear differences in stem solidness and fructan content exhibited lesser grain yield reduction under drought condition.

In the present study, additive main effects and multiplicative interactions (AMMI) biplot analyses was used to dissect genotype x environment interaction (GEI) and to identify location specific and widely adapted genotypes for root branches, diameter and length in ashwagandha [Withania somnifera (L.) Dunal]. Trials were conducted in randomized complete block design (RCBD) with two replications over three consecutive years at three different locations. ANOVA analysis revealed environment, G×E interaction and genotype effects to contribute significantly (p less than 0.001) towards total sum of squares for root branches (61.00%, 22.18% and 14.00%); root diameter (51.06%, 24.26% and 15.34%) and root length (65.67%, 20.82% and 11.39%). Further, the GEI for these traits was mostly explained by the first, second and third principal component axis (IPCA1, IPCA2 and IPCA3). AMMI1 and AMMI2 biplot analyses showed differential stability of genotypes for root branches, diameter and length with few exceptions. Environmental contribution towards the genotypic performance from AMMI1 and AMMI2 analysis for root traits except environment Bhi16 contribution for root diameter and root length. AMMI1 biplots and simultaneous selection index (SSI) statistics identified SKA-11 as the most desirable genotype for root branches and length while SKA-26 and SKA-27 for root diameter. The ashwagandha genotypes identified for root attributes could be advocated either for varietal recommendation or in varietal development program.
Effect of gamma ray irradiated pollen technique on seed development pattern in Citrus
Authors: Kundu Manoj , Dubey Anil
Published: June 2021

In modern fruit breeding, to reduce the breeding cycle, induction of haploid plants through irradiated pollen technique is of paramount importance. However, the major drawback is the sensitivity of pollen to higher irradiation doses as it induces abnormality in double fertilization process. Hence, optimization of irradiation doses for maximum recovery of healthy seed is very important. Present work analyzed the seed developmental pattern of Citrus grandis, pollinated with gamma irradiated pollen (100-500 Gy) of C. limon, C. limetta, and C. sinensis. Not a single fruit was retained on the tree till maturity in C. grandis × C. limon crosses; however, in other two cross combinations, fruits were harvested at maturity only up to 300 Gy irradiation doses. Among the harvested fruit, normal seed decreased gradually with increasing irradiation doses and less than 5 normal seeds per fruit were obtained at 300 Gy with maximum in C. grandis × C. limetta cross. However, abnormal and empty number no. of seeds has increased significantly with increasing irradiation doses. Developmental pattern of embryo and endosperm within normal seeds was also influenced significantly by irradiation treatment. At higher doses, seeds number with both embryo and endosperm was decreased gradually and at 300 Gy, it was reduced to 59.47% as compared to control.

Published: June 2021

The variation for 100 seed weight in F2 population derived from a cross, AGS456 (an exotic vegetable type from Taiwan)/SL958 of soybean followed a normal curve with a range of 8.00-27.22g indicating quantitative nature of genetic control for seed size. Parental lines were screened with 207 SSR markers to identify polymorphism and 90 primer pairs detected polymorphism between the parents. These ninety markers were used for detecting polymorphism between two extreme bulks for seed weight. Out of these, 18 primer pairs were polymorphic for the bulks and were used for bulk segregant analysis in 200 F2 plants. One major QTL for seed weight was identified on LG M with Sat_244 and Satt175 as flanking markers, explaining 19.0 per cent phenotypic variation. Two minor QTLs were also identified on LG D1b, one in interval Satt041-Sat_069 with an estimated phenotypic variation (R2) of 6.0 per cent and the other in interval Sat_069-Sat_0183 estimating 7.0 per cent phenotypic variance. The markers flanking TLs may help in marker-assisted selection (MAS) for improvement of seed weight in soybean after fine mapping and validation.

Published: June 2021

Knowledge about the type of mutagen used and its optimized dose are of paramount importance to design and implement any plant mutation breeding programme. Present study was first time carried out to evaluate the comparative effectiveness, radio-sensitivity behavior and relative biological effectiveness of four physical mutagens viz., gamma rays, X-rays, electron beam and proton beam on two short grain aromatic rice landraces viz., Samundchini and Vishnubhog. The seeds of these two varieties were treated with 15 different doses of all four mutagens, ranging from 50Gy to 750Gy with an interval of 50Gy. Germination percentage and seedling growth parameters were recorded at seven and 15 days after sowing, respectively in two replications. It was observed that germination percentage, shoot and root length of the seedling gradually declined with the increase in doses of all the physical mutagens. On the basis of these observations, LD50 and GR50 doses were calculated. The present study reports the optimum range of doses for gamma ray (280 to 350 Gy); electron beam (290 to 330Gy); X-ray (200 to 250 Gy) and proton beam (150 to 200Gy). GR50 doses were observed higher than LD50 doses for all the mutagens in both landraces. However, Samundchini showed higher LD50 and GR50 doses than Vishnubhog indicating later to be more radio-sensitive. Furthermore, both the genotypes were highly radio-sensitive for proton beam and least for gamma rays. Similarly, high relative biological effectiveness was observed for proton beam followed by X-ray, electron beam and gamma rays indicating their decreasing trend of penetration capacity and lethality. Results of present study will be useful for plant breeders to use the above mutagens in an appropriate dose for mutation breeding in rice.
Genetics of anther culture capability traits and its association with seed yield traits in sesame
Authors: Dash Manasi , Naik Smrutirekha , Pradhan Banshidhar
Published: June 2021

Successful development of heterotic hybrids in the autogamous sesame crop depends largely on the general combining ability of the parents as well as the specific combining ability of the hybrids produced from them. Homogeneity of Vr -Wr values and non-significance of regression coefficient (b) in a 6 parents half diallal cross were found in respect of capsule length, seeds per capsule, plant height, callus induction frequency, days to callus induction and response to somatic embryogenesis indicating validity of Hayman’s assumptions. The estimates of D, H1 and H2 components indicated predominance of non-additive gene action in the inheritance of these six traits, and the ADD estimates indicated overdominance for all these characters. The estimates of F and KD/KR indicated presence of more of dominant alleles in the parental population except for response to somatic embryogenesis. Strong positive association was recorded between seed yield and in vitro traits viz., callus induction frequency, callus fresh weight and somatic embryogenesis. This indicates that anther culture technique can assist in early screening for combining ability of parents as well as direct selection for heterotic crosses at an earlier stage of hybrid breeding programme.
Buckwheat: A critical approach towards assessment of its potential as a super crop
Authors: Chrungoo Nikhil K. , Chettry Upasna
Published: June 2021

Buckwheat has attracted considerable interest amongst the global scientific community due to its nutritional and pharmaceutical properties. It is a low input crop whose cultivation has persisted through centuries of civilization in almost every country where cereals were cultivated. The crop is an important source of rutin, an important flavonoid which is known to have cardioprotective, vasoprotective, antihypertensive, anti-inflammation, cytoprotective and anti-diabetic properties. Grains of buckwheat are a rich source of protein with a balanced amino acid composition, gluten free flour, dietary fibre, vitamins, resistant starch, phytosterols, fagopyrins, fagopyritols and phenolic compounds. Buckwheat is a short season crop which completes its life cycle in 70-90 days and can grow in wide range of environmental conditions including marginal lands and rocky, poorly tilled soils. The protein content in buckwheat flour is higher than in commonly used cereals such as rice, wheat, millet, sorghum and maize. Buckwheat grain protein is rich in lysine and arginine, which are generally limiting in other cereals. Because of a low Lys/ Arg and Met/Gly ratio, buckwheat protein has strong hypolipidemic activity. While Buckwheat is considered as a healthy food because of its nutraceutical properties, low yields due to seed shattering because of pedicel breaking and heterozygosity due to self-incompatibility as a consequence of dimorphic heterostylism have always remained major problems in achieving large scale incorporation of common buckwheat (Fagopyrum esculentum) in the agricultural portfolio. The present review highlights the multicore potential of buckwheat as a super crop to meet the challenges of food and nutritional security.

Published: June 2021

Triallel crosses can be readily exploited as breeding tool for developing commercial hybrids with traits of genetical and commercial importance by acquiring information on specific combining ability effects along with general combining ability effects if the experimentation size is reduced to an economical extent. In this paper, methods of constructing designs involving partial triallel crosses in smaller blocks using different types of lattice designs have been introduced. The designs have low degree of fractionation, which suggests their utility when there is a resource crunch. Canonical efficiency factor of these designs relative to an orthogonal design with same number of lines, assuming constant error variance for both situations, is high indicating that adoption of these designs for the trials could bring about improvement as the recommendations from the experiment will be associated with a high precision.

Published: June 2021

In present study, 67 JNPT (Jawahar New Plant Type) lines were evaluated for 28 morphological and quality traits planted in RCBD with three replications. Principal Component Analysis (PCA) revealed that out of 28, only eight PCs exhibited more than 1.0 eigen value and showed about 81.84% total variability. For selecting the high yielding genotypes in rice, the characters viz., spikelet density, spikelet fertility, number of tillers plant–1and panicle weight plant–1 may be considered. On the basis of high PC score ten most prominent lines namely JNPT-1059-9, JNPT-1059- 10, JNPT1062-1, JNPT-1062-2, JNPT-1064-9, JNPT-1065-1, JNPT-1065-2, JNPT1065-3, JNPT-1066-52 and JNPT-1068- 65 were identified for yield and quality traits.

Phytic acid (PA) acts as chelator of cationic mineral elements iron (Fe) and zinc (Zn) and obstructs their absorption in the human gut. We have evaluated a set of 162 traditional rice landraces for phytic acid phosphorus (PA-P), inorganic phosphorus (Pi) and total phosphorus (TP). Wide variability was observed for PA-P, Pi and TP ranging from 1.12 to 3 mg/g, 0.004 to 0.16 mg/g and 1.17 to 3.04 mg/g respectively. The mineral micronutrients, Fe and Zn were not in correlation with PA-P, Pi and TP implicating the possibility of their independent improvement while PAP showed a significant positive correlation with TP and significant negative correlation with Pi. Principal component analysis (PCA) identified two principal components PC1 and PC2, explaining 50.6 % and 32.1 % of the total variation, respectively. Cluster analysis grouped the accessions into four clusters. The study has also led to the identification of promising donors such as P1490 and Gowri with low PA content to be utilized in rice biofortification programmes.

Vitamin A deficiency (VAD) is a global health problem. Maize naturally accumulates carotenoids including ?-carotene, a major source of vitamin A. Thirty-seven Indian maize genotypes were screened for total carotenoids and ?carotene content. A positive significant association of kernel colour was observed with total carotenoid but not for ?-carotene. The level of ?-carotene among the selected 37 genotypes was low (0.14 to 4.63µg/g) as compared to total carotenoids (15.94 to 66.46 µg/g) thus necessitates the introduction and deployment of lines with high ?carotene. Hence, 54 inbred lines developed under the HarvestPlus programme were screened with functional markers of lcyE and crtRB1 genes of the carotenoid biosynthetic pathway. Three genotypes (HP704-13, HP704- 22, and HP704-23) amplified most of the favorable alleles for both these genes. However, due to long Anthesis Silking Interval (ASI) and poor adaptation HP704-13 and HP704-23 could not be maintained. Under normal storage condition genotype, HP704-22 recorded 7.32 µg/g of ?-carotene which can be used as a donor for provitamin-A or to diversify the Indian germplasm.

This research discusses the associative meaning of dictions in face wash products for men and women. The study focuses on  the use of different dictions displayed in the product description of face wash products. The descriptions of 60 face wash products, 30 for men and 30 for women, were collected. The approach used in this research is semantic analysis. This research aims to discover the associative meanings which occur in the dictions and to find out whether they correspond with the consumer’s point of view. The result shows that the dictions used for face wash products for women give an impression of beauty for the female facial skin, such as lovely, sparkling, flawless, and pearly. On the other hand, the dictions for men’s products give an impression of strengths, such as fighter, buster, energy, and active. This leads to the conclusion that the dictions in face wash products for women are related to ideal physical characteristics of female skin. As for men’s products, the dictions are related to general characteristics of being an active man.

Published: June 2021

Cohesion has become a crucial component of academic writing that promotes the semantic connection within phrases and sentences. The objectives of this literature review research are to identify different forms of cohesions and the most common form of cohesion in articles on EFL academic writing. This study extracted records from Google Scholar and Scopus databases and selected 20 studies in the last five years out of 700 on the use of cohesions in the writing of EFL students. The data was gathered by sorting similar messages, finding cohesions, clarifying cohesions, and counting the cohesions with the highest percentage. The research results show that the published articles containing cohesions represent the reference (35%), paired conjunctions (15%), reiteration (40%), and collocation (10%). The most common type of cohesion is reiteration, which is essential for comprehending what the authors mean in their published works. Cohesions in theoretical and practical grounds contribute to the explicitness of semantic components of words or phrases to generate the messages conveyed to readers.
Student Seating Position and Their Academic Performance in Computer Science Major
Authors: Kurniawati Gisela , Karnalim Oscar , Budi Setia
Published: June 2021

A number of studies regarding the correlation between student seating position and their academic performance have been conducted. However, only a few of them focusing on computer science major, which is argued to be unique in terms of teaching style and classroom layout; as the discipline puts more emphasise on hands on activity like programming, system and network configuration. Further, among those works focusing on that major, none of them specifically address undergraduate students. This paper presents an observational study involving 426 computer science undergraduate students. The study covers student activity over one academic semester. A questionnaire survey measuring student awareness about that correlation in their seating preference was also performed, with 126 students as the respondents. In general, the correlation only exists on some circumstances like student major and lecture time. Further, the seating preference can be driven by the awareness of that correlation with some motivating factors like friends, whiteboard position, and personal habit. Per occasion, it is suggested to analyse the class circumstances and the student motivating factors prior performing further actions.

Published: June 2021

Depression and social anxiety are the two main negative impacts of cyberbullying. Unfortunately, a survey conducted by UNICEF on 3rd September 2019 showed that 1 in 3 young people in 30 countries had been victims of cyberbullying. Sentiment analysis research will be conducted to detect a comment that contains cyberbullying. Dataset of cyberbullying is obtained from the Kaggle website, named, Toxic Comment Classification Challenge. The pre-processing process consists of 4 stages, namely comment generalization (convert text into lowercase and remove punctuation), tokenization, stop words removal, and lemmatization. Word Embedding will be used to conduct sentiment analysis by implementing Word2Vec. After that, One-Against-All (OAA) method with the Support Vector Machine (SVM) model will be used to make predictions in the form of multi labelling. The SVM model will go through a hyperparameter tuning process using Randomized Search CV. Then, evaluation will be carried out using Micro Averaged F1 Score to assess the prediction accuracy and Hamming Loss to assess the numbers of pairs of sample and label that are incorrectly classified. Implementation result of Word2Vec and OAA SVM model provide the best result for the data undergoing the process of pre-processing using comment generalization, tokenization, stop words removal, and lemmatization which is stored into 100 features in Word2Vec model. Micro Averaged F1 and Hamming Loss percentage that is produced by the tuned model is 83.40% and 15.13% respectively.

Published: June 2021

Background: Aberrant cell cycle re-entry is a well-documented process occurring early in Alzheimer’s disease (AD). This is an early feature of the disease and may contribute to disease pathogenesis. Objective: To assess the effect of forced neuronal cell cycle re-entry in mice expressing humanized Aβ, we crossed our neuronal cell cycle re-entry mouse model with AppNLF knock-in (KI) mice. Methods: Our neuronal cell cycle re-entry (NCCR) mouse model is bitransgenic mice heterozygous for both Camk2a-tTA and TRE-SV40T. The NCCR mice were crossed with AppNLF KI mice to generate NCCR-AppNLF animals. Using this tet-off system, we triggered NCCR in our animals via neuronal expression of SV40T starting at 1 month of age. The animals were examined at the following time points: 9, 12, and 18 months of age. Various neuropathological features in our mice were evaluated by image analysis and stereology on brain sections stained using either immunofluorescence or immunohistochemistry. Results: We show that neuronal cell cycle re-entry in humanized Aβ plaque producing AppNLF KI mice results in the development of additional AD-related pathologies, namely, pathological tau, neuroinflammation, brain leukocyte infiltration, DNA damage response, and neurodegeneration. Conclusion: Our findings show that neuronal cell cycle re-entry enhances AD-related neuropathological features in AppNLF mice and highlight our unique AD mouse model for studying the pathogenic role of aberrant cell cycle re-entry in AD.

Published: June 2021

Background: Ample evidence from clinical and pre-clinical studies suggests mid-life hypercholesterolemia as a risk factor for developing Alzheimer’s disease (AD) at a later age. Hypercholesterolemia induced by dietary habits can lead to vascular perturbations that increase the risk of developing sporadic AD. Objective: To investigate the effects of a high fat/cholesterol diet (HFCD) as a risk factor for AD by using a rodent model of AD and its correspondent control (healthy animals). Methods: We compared the effect of a HFCD in normal mice (non-transgenic mice, NTg) and the triple transgenic mouse model of AD (3xTgAD). We evaluated cognitive performance in relation to changes in oxidative metabolism and neuron-derived nitric oxide (•NO) concentration dynamics in hippocampal slices as well as histochemical staining of markers of the neurovascular unit. Results: In NTg, the HFCD produced only moderate hypercholesterolemia but significant decline in spatial memory was observed. A tendency for decrease in •NO production was accompanied by compromised mitochondrial function with decrease in spare respiratory capacity. In 3xTgAD mice, a robust increase in plasma cholesterol levels with the HFCD did not worsen cognitive performance but did induce compromise of mitochondrial function and significantly decreased •NO production. We found increased staining of biomarkers for astrocyte endfeet and endothelial cells in 3xTgAD hippocampi, which was further increased by the HFCD. Conclusion: A short term (8 weeks) intervention with HFCD can produce an AD-like phenotype even in the absence of overt systemic hypercholesterolemia and highlights mitochondrial dysfunction as a link between hypercholesterolemia and sporadic AD.

Background: Phospholipid transfer protein (PLTP) belongs to the lipid transfer glycoprotein family. Studies have shown that it is closely related to Alzheimer’s disease (AD); however, the exact effect and mechanism remain unknown. Objective: To observe the effect of PLTP overexpression on behavioral dysfunction and the related mechanisms in APP/PS1/Tau triple transgenic (3×Tg-AD) mice. Methods: AAV-PLTP-EGFP was injected into the lateral ventricle to induce PLTP overexpression. The memory of 3×Tg-AD mice and wild type (WT) mice aged 10 months were assessed using Morris water maze (MWM) and shuttle-box passive avoidance test (PAT). Western blotting and ELISA assays were used to quantify the protein contents. Hematoxylin and eosin, Nissl, and immunochemistry staining were utilized in observing the pathological changes in the brain. Results: 3×Tg-AD mice displayed cognitive impairment in WMW and PAT, which was ameliorated by PLTP overexpression. The histopathological hallmarks of AD, senile plaques and neurofibrillary tangles, were observed in 3×Tg-AD mice and were improved by PLTP overexpression. Besides, the increase of amyloid-β42 (Aβ42) and Aβ40 were found in the cerebral cortex and hippocampus of 3×Tg-AD mice and reversed by PLTP overexpression through inhibiting APP and PS1. PLTP overexpression also reversed tau phosphorylation at the Ser404, Thr231 and Ser199 of the hippocampus in 3×Tg-AD mice. Furthermore, PLTP overexpression induced the glycogen synthase kinase 3β (GSK3β) inactivation via upregulating GSK3β (pSer9). Conclusion: These results suggest that PLTP overexpression has neuroprotective effects. These effects are possibly achieved through the inhibition of the Aβ production and tau phosphorylation, which is related to GSK3β inactivation.

The uncapacitated transportation problem (UTP) deals with minimizing the transportation costs related to the delivery of a homogeneous product from multi-suppliers to multi-consumers. The application of the UTP can be extended to other areas of operations research, including inventory control, personnel assignment, signature matching, product distribution with uncertainty, multi-period production and inventory planning, employment scheduling, and cash management. Such a UTP with interval-defined demands and suppliers capacities (UTPIDS) is investigated in this paper. In UTPIDS, the demands and suppliers capacities may not be known exactly but vary within an interval due to variation in the economic conditions of the global economy. Following the variation, the minimal total cost of the transportation can also be varied within an interval and thus, the cost bounds can be obtained. Here, although the lower bound solution can be attained methodologically, the correct estimation of the worst case realization (the exact upper bound) on the minimal total transportation cost of the UTPIDS is an NP-hard problem. So, the decision-makers seek for minimizing the transportation costs and they are interested in the estimation of the worst case realization on these minimal costs for better decision making especially, for proper investment and return. In literature very few approaches are available to find this estimation of the worst case realization with some shortcomings. First, we demonstrate that the available heuristic methods fail to obtain the correct estimation of the worst case realization always. In this situation, development of a better heuristic method to find the better near optimal estimation of the worst case realization on the minimal total costs of the UTPIDS is desirable. Then this paper provides a new polynomial time algorithm that runs in O (N2) time (N, higher of the numbers of source and destination nodes) for better estimation. A comparative assessment on solutions of available benchmark instances, some randomly generated numerical example problems and a real-world application shows promising performance of the current technique. So, our new finding would definitely be benefited to practitioners, academics and decision makers who deal with such type of decision making instances.
