Chickpea (Cicer arietinum L.) is one of the most cultivating pulse crops globally and in India, its productivity is limited blisteringly by Gram pod borer insect (Helicoverpa armigera) and Fusarium wilt disease. Pyramiding of these two biotic stress resistance in a single genotype is expected to increase crop productivity and reduces the usage of pesticides/fungicides by farmers, which boost economic viability in the cultivation of this crop. Hence, we planned to transfer the cry1Ac gene, which imparts pod borer resistance from BS 100B event, to Super Annigeri-1(SA-1), the wilt resistant variety bred through marker-assisted backcrossing.The F1 plants developed by SA-1 X BS 100B crosses were confirmed with cry1Ac gene-specific marker and polymorphic SSR marker (ICCM0299).The expression of the cry1Ac gene at the transcriptional level through reverse transcription polymerase chain reaction and at the protein level through enzyme-linked immuno sorbent assay was confirmed in F1. The presence of a single copy of a gene integration, stably, was confirmed through the inheritance of the cry1Ac gene and 3:1 segregation ratio in F2 using Chi-square test. BS 100B (donor parent), F1 and F2 plants, respectively recorded 21.47 µg, 20.43 µg and 15.31-21.17µg of Cry1Ac protein/g of leaf tissue in quantitative ELISA test that is enough to record pest resistance. This is the first study to combine resistance to both pod-borer and Fusarium wilt by intercrossing of one cry1Acevent (BS 100B) together with SA-1 developed through molecular breeding and developed progenies have shown resistance to both biotic stresses.

Tomato cultivation in Côte d'Ivoire is facing problems related to soil depletion. However, mineral fertilization of these soils remains expensive and almost inaccessible to many farmers in rural areas and contributes to environmental pollution. The aims of this work is to improve the growth and production of tomato by using the mycelium of Pleurotus ostreatus. Trials were carried out on plants from two tomato varieties F1 cobra 26 and Petomech. Four types of treatments were applied in this study; they are 10g of Pleurotus ostreatus mycelium; 5gof Pleurotus ostreatus mycelium; NPK and a control. The different treatments were done one week before transplanting and one week after transplanting. At the end of this work, all the treated plants had a significant effect on the different growth parameters studied compared to the control. The plants treated with 10g of Pleurotus ostreatus mycelium, one week before transplanting to Cobra 26, gave the best results of collar diameter, plant height and number of leaves. For the treatment one week after transplanting, only the plants treated with 10 g of Pleurotus ostreatus mycelium improved the diameter at the collar, the height of the stems and the number of leaves.
Tannase Enzyme for Microbial Degradation of Industrial Effluents: A Review
Authors: Mohamed Farhaan Makba , C. Patil Rajesh
Published: March 2023

Pollution is a pervasive phenomenon and inconvenient truth. Effluents from domestic and industrial sources are being released into the water bodies. They not only pollute the water bodies but also disturb the normal biological cycles of associated organisms. Industrial effluents are more polluting in nature as compared to domestic effluents. Industries utilize humongous quantities of water for cooling, cleaning, transportation and other tasks. In the process the water interacts with different chemicals, some are toxic while some may be neutral. It forms a harmful effluent and when it is disposed of in water bodies, causes water pollution. Wastewater from the brewery, tannery, paper pulp industries, food industries and textile industries are rich in organic contaminants. Removal of degradation of these contaminants is quite important before their disposal into water bodies. Various methods are available for effective removal of these contaminants from the effluents namely physical, chemical & biological. Biological treatment involves both aerobic & anaerobic treatment as well as degradation with microbes. Microbes contain several enzymes that can effectively degrade different organic compounds. Tannase isolated from some fungal and bacterial strains is effective in the degradation of tannin present in the effluent from the leather industry.

The main means of controlling Fusarium wilt of oil palm is the use of tolerant hybrids. The objective of this study was to show the pathogenic, morphological and molecular differences of Fusarium oxysporum f sp elaeidis (Foe) isolates from Ivory Coast. A total of 13 Fusarium oxysporum (Fo) strains were isolated from fusarium-damaged oil palm organs from Héania, La Mé, Anguédedou, Dabou and Grand-Bereby(SOGB) localities. Fo isolates were subjected to pathogenicity tests, morphological, and morphometric characterization, molecular diversity (PCR-ITS-RFLP) and DNA sequencing. Results showed that six strains are pathogenic to oil palm. Isolates from Anguededou (A10), Dabou (D2-6) and La Mé (L60) were more aggressive, with incubation time ranging from five to six weeks, while those from Héania (E69), SOGB (So-19) and Mono 179 strains recorded from 8 to 20 weeks incubation time and showed less aggressive. Morphometric characterization showed that length of microconidia and macroconidia (two partitions) of Foe are shorter than Fo. For molecular level, electrophoretic profiles were different from one enzyme to another and identical for the same enzyme. The high aggressive strains obtained in this study can be use to screen hybrids varieties.

Genomic Selection and Genetic Tools to Improve Fertility Traits
Authors: P. Nadri H. Asadollahi , Bagheri M.
Published: March 2023

Improving dairy cow fertility by means of genetic selection is likely to become increasingly important, since it is now well established that declining fertility cannot only be arrested by improved management. Fertility is a major concern in the dairy cattle industry and has been the subject of numerous studies over the past 20 years. Surprisingly, most of these studies focused on rough female phenotypes and, despite their important role in reproductive success, male- and embryo-related traits have been poorly investigated. In recent years, the rapid and important evolution of technologies in genetic research has led to the development of genomic selection. genomic selection (GS) is a form of marker-assisted selection in which genetic markers covering the whole genome are used so that all quantitative trait loci (QTL) are in linkage disequilibrium with at least one marker. GS can increase the accuracy of selection, shorten the generation interval by selecting individuals at the early stage of life, and accelerate genetic progress. With the availability of high density whole genome SNP (single nucleotide polymorphism) chips for livestock, GS is reshaping the conventional animal breeding systems. In many countries, GS is becoming the major genetic evaluation method for bull selection in dairy cattle and GS may soon completely replace the traditional genetic evaluation system. In recent years, GS has become an important research topic in animal, plant and aquiculture breeding and many exciting results have been reported.
