CRISPR--a widespread system that provides acquired resistance against phages in bacteria and archaea.

CRISPR – a widespread system that provides acquired resistance against phages in bacteria and archaea Rotem Sorek*, Victor Kunin and Philip Hugenholtz Joint Genome Institute, 2800 Mitchell Drive, Walnut Creek, CA 94598 * Corresponding author: rsorek@lbl.gov Abstract Arrays of clustered, regularly spaced short palindromic repeats (CRISPR) are widespread in the genomes of many bacteria and almost all archaea. These arrays are composed of direct repeats sized 24-47 bp separated by similarly sized non-repetitive sequences (spacers). It was recently experimentally shown that CRISPR arrays, along with a group of associated proteins, confer resistance to phage. Following exposure to phage, bacteria integrate new spacer sequences that are derived from the phage genome. Acquisition of these spacers enables the bacterial cell to shutdown the phage attack, presumably by an RNA-interference-like mechanism. This Progress discusses the structure and function of CRISPRs and the implications of this new antiviral mechanism in bacteria.
Characterization of Transgenic Tall Fescue Plants Overexpressing NDP Kinase Gene in Response to Cold Stress

Sang-HoonLee *,** ,Ki-WonLee*,** ,KyungHeeKim *,Dae-JinYun *,Sang-SooKwak***andByung-HyunLee *ABSTRACTOxidative stress is the main limiting factor in crop productivity. To solve global environmental problemsusing the plant biotechnology, we have developed on the oxidative stress-tolerant transgenic tall fescueplants via Agrobacterium -mediated genetic transformation method. In order to develop transgenic tall fescue(Festucaarundinacea Schreb.) plants with enhanced tolerance to multiple environmental stresses, nucleotidediphosphate kinase gene under the control of CaMV35S promoter were introduced into genome of tallfescue plants. Proteomic analysis revealed that transgenic tall fescue not only accumulated NDP kinase 2protein in their cells, but also induced several other antioxindative enzyme-related proteins. When leaf discsof transgenic plants were subjected to cold stress, they showed approximately 30% less damage thanwild-type plants. In addition, transgenic tall fescue plants showed normal growth when transgenic plantswere subjected to 4 for 3 days treatments. These results suggest that transgene is important in ROSscavenging by induction of antioxidative proteins, and could improve abiotic stress tolerance in transgenictall fescue plants.

Studies of i n vitro Adventitious Root Induction and Flavonoid Profiles in Rumex crispus

Flavonoids are the principal bioactive components of the medicinal plant Rumex crispus, to which various diverse pharmacological properties are attributed. Adventitious root culture of leaf explants of R. crispus was established using different MS media supplemented by different concentrations of Auxins and a combination of Naphthalene Acetic Acid (NAA) and Kinetin (Kn) for growth and flavonoids production. NAA was more effective than Indole Acetic Acid (IAA) to induce adventitious roots. 5 µM NAA treatments had the most number of roots. Maximum root length and root fresh weight were obtained in 0.5 µM Kn. 0.5 µM Kn using in combination with NAA in culture medium increased root fresh weight. Results of 2-dimensional paper and thin layer chromatography of the samples extracts showed that hormons are influenced flavonoids in culture medium. The combination of NAA and Kinetin in culture medium reduced or suppressed Myricetin and Naringenin production and increased number of aglycones. Quercetin was not found in root on medium containing 0.5 µM Kn. Isorhamnetin, Kaempferol, Rhamnetin and Rutin were found in all of treatments that had produced roots. It is believed that root flavonoids are related to root growth, development and differentiation in R. Crispus species.
The Composition of Essential Oil from Nepeta cataria and Its Effect on Microorganism

We analyzed the total yields and composition of essential oils in leaf extracts of Nepeta cataria by Gas Chromatography Mass Spectrometry (GC-MS). Thirty-six compounds representing 97.0% of total oil were detected. The major constituents of essential oils in Nepeta cataria were nepetalactone (90.9%), unidentified compound (Retention time 17.35; 1.82%), 1,8-cineol (1.49%), (1.12%), and (1.078%). The volatile compounds in leaf extracts of N. cataria concentrated to nepetalactone () remarkably. In the essential oil of N. cataria cis,trans-nepetalactone () and cis,cis-nepetalactone () were found as the main constituents. The effects of essential oil of N. cataria on the growth of six microorganisms (Bacillus cereus, B. subtilis, B. amyloliquefaciens, Escherichia coli, Staphylococcus aureus subsp. aureus, and Pseudomonas aeruginosa) were investigated. The essential oil of N. cataria had strong inhibitory effect on the growth of three fungal species (Bacillus cereus, B. subtilis, and B. amyloliquefaciens). The essential oil from N. cataria was found to have a low antimicrobial activity against Staphylococcus aureus subsp. aureus, while no activity were found against Escherichia coli and Pseudomonas aeruginosa. Results indicate the significant antimicrobial effect, which may be depended on the yield of nepetalactone.

OLEUM project. Analysis of volatile compounds of extra virgin and virgin olive oil with a different geographical origin by flash gas chromatography

This data set contains the underlying data of the scientific publication: Palagano R. et al., 2019. Discrimination of virgin olive oils with different geographical origin: a rapid untargeted chromatographic approach based on volatile compounds. This publication will be submitted to a scientific journal. To ensure that consumers are not misled, European Regulation n. 29/2012 establishes specific rules to report the geographical origin of extra virgin and virgin olive oils on the product label, but an analytical procedure to verify this information has not been yet defined. A flash gas chromatography and untargeted chemometric data elaborations for the rapid screening of 210 extra virgin and virgin olive oils with different geographical provenance was applied. The analysis of volatile compounds was carried out by the Flash Gas Chromatography Electronic Nose Heracles II (Alpha MOS, Toulouse, France). The instrument was equipped with two metal capillary columns (MXT-5 and MXT-1701) working in parallel mode. At the end of each column, a FID detector was placed and the acquired signal was digitalized every 0.01 sec. This data set contains the raw data (intensity values for each point of the chromatogram considering that the signal was digitalized every 0.01 sec) obtained from the analysis of all the sample by flash gas chromatography. Only data obtained from the column MXT-5 are reported since this column showed a higher discriminating power.
An Empirical Effect of the Belief Variables on Recommendation Intention for Using Kiosk Service

The purpose of this study is to identify belief variables of kiosk that affect satisfaction and recommendation intention by applying vertically extended technology acceptance model (TAM). As results of this study are as follows. Firstly, the perceived usefulness and perceived ease of use have an impact on satisfaction statistically. Second, the perceived usefulness and perceived enjoyment of the kiosk showed a positive(+) influence on the recommendation intention. Third, users who satisfied with kiosk service have strong recommendation intention to their friends, family and colleagues so on. These findings support that the usefulness and usability of the new information technology identified in the existing technology acceptance model is a key variable affecting user reactions (satisfaction and recommendation intention). Additionally, the perceived enjoyment is an important factor as new belief variable for explaining the formation of recommendation intention through satisfaction of kiosk service. The results of this study contribute to verifying the empirical model between the belief variables(perceived usefulness, perceived ease of use, perceived enjoyment) and the recommendation intention.
SRAP markers for population genetic structure and genetic diversity in Malus sieversii from Xinjiang, China.

TitleSRAP Markers for Population Genetic Structure and Genetic Diversity in Malus sieversii from Xinjiang,China AuthorZHANG Chun-yu1,2,CHEN Xue-sen1,LIN Qun1,YUAN Zhao-he3,Zhang Hong1,ZHANG Xiao-yan1,LIU Chong-qi1,and WU Chuan-jin1(1State Key Laboratory of Crop Biology,Shandong Agricultural University,Tai'an,Shandong 271018,China;2College of Plant Science,Jilin University,Changchun 130062,China;3Shandong Institute of Pomology,Tai'an,Shandong 271000,China) The genetic diversity and genetic structure of four Malus sieversii eco-geographical populations from Xinjiang,China were studied by SRAP marker.The results showed that 209 bands were amplified totally by ten pair SRAP primers,of which 206 bands(98.56%)were polymorphic in the species level and the number of polymorphic bands were 180,169,178 and 165,respectively,at Gongliu,Xinyuan,Huocheng,and Yumin populations.The average panmictic heterozygosity(hs=0.3037±0.0058)in the Gongliu population was the highest,followed by the Huocheng population.UPGMA cluster analysis and genetic differentiation among populations showed that there had been closer genetic relationship between Gongliu and Xinyuan populations and between Huocheng and Yumin populations and lower genetic variation between the populations.For M.sieversii,genetic variation within population,which was higher than that between the populations,accounted for 87.9% of total variation.The principal coordinates analysis showed that the four populations were relatively independent populations,in which between the Gongliu and Xinyuan populations and that between Huocheng and Yumin populations had higher gene exchange.On the basis of the study of population genetic structure and genetic diversity,Gongliu population should be given a high priority consideration in Malus sieversii germplasm conservation both in situ and ex situ.

Biology of floral scent

As with nearly all living creatures, humans have always been attracted and intrigued by floral scents. Yet, while we have been manufacturing perfumes for at least 5000 years to serve a myriad of religious, sexual, and medicinal purposes, until very recently, the limitation of our olfactory faculty has greatly hindered our capacity to clearly and objectively measure scent. Today, thanks to advances in practical methodologies and affordable instrumentation, we are now able to collect, separate, and identify volatile compounds with aromatic impact. These advances are leading to much intensive investigation that has already resulted in many highly insightful and useful discoveries.Biology of Floral Scent provides the first comprehensive treatment of the biology of floral scents. It reviews the impressive research being done across several disciplines, incorporating molecular biology, enzymology, chemistry, entomology, genetic engineering, and functional genomics. Organized into a single volume for the first time, this landmark work covers every major aspect of floral scent research .
The Mexican Asteroid Photometry Campaigns: Aiming for Asteroids’ Rotation Periods

Abstract Thousands of new asteroids are discovered every year and the rate of discovery is by far larger than the determination rate of their physical properties. In 2015 a group of researchers and students of several Mexican institutions have established an observational program to study asteroids photometrically. The program, named Mexican Asteroid Photometry Campaign, is aiming to derive rotation periods of asteroids based on optical photometric observations. Since then four campaigns have been carried out. The results obtained throughout these campaigns, as well as future work, are presented.

Membrane Lipids of Yeast: Biochemical and Genetic Studies

INTRODUCTION Saccharomyces cerevisiae is a fairly typical eukaryotic organism with respect to the membranous organelles it contains, as well as the lipids that comprise its membranes. Like other eukaryotes, it synthesizes and incorporates sterol into its membranes. In addition, its membranes contain a typically eukaryotic mixture of phospholipids, including sphingolipids, cardiolipin, phosphatidylserine, phosphatidylethanolamine, phosphatidylcholine, and phosphatidylinositol (see Fig. 5). The pathways for the synthesis of yeast membrane lipids are increasingly well characterized. In addition, a number of mutations affecting these pathways have been characterized, and reliable methodologies for isolation of some subcellular membrane fractions are being developed. As a result, S. cerevisiae is an attractive organism in which to conduct studies on the roles of specific lipids in membrane biogenesis and membrane-mediated processes. In bacteria (for reviews, see Silbert et al. 1974; Silbert 1975; Raetz 1978), lipid mutants have been used to study the role of lipid synthesis on membrane biogenesis and to manipulate membrane lipid composition. Such experiments permit assessment of the role(s) of various lipids in membrane function and allow the physical properties of the membrane lipid bilayer to be experimentally manipulated in vivo. Since S. cerevisiae is a eukaryotic organism, yeast lipid mutants can be used for probing the role of lipids in the biogenesis and functioning of a variety of membranous organelles. In this paper studies of this kind are reviewed together with genetic and biochemical studies on the pathways involved in lipid synthesis in yeast.

Microbial activities of faeces from unweaned and adult pigs, in relation to selected fermentable carbohydrates

A comparison of in vitro microbial activity was made between inocula from faeces of adult and unweaned pigs, using a range of carbohydrate-rich substrates. The substrates tested were classified into groups (fibre-rich, grains, gums, pectin, saccharides, storage carbohydrates, and miscellaneous). Proximate and fibre analyses were determined for all substrates tested. Fermentation kinetics were measured according to the cumulative gas production technique. End-point products such as gas, volatile fatty acids and ammonia were also determined. The faeces from the adult pigs (ATF) were collected from four castrated finisher pigs (Dutch Landrace × Great Yorkshire). These were offered a diet based on highly digestible maize starch and fish meal, so as to be as free as possible of fermentable carbohydrates. The unweaned piglet faeces were collected from 19 unweaned piglets (male and female) which were 27 to 30 days old. The parameters were tested for significance by an analysis of variance using the Tukey's studentized range test of multiple comparisons. There were significant differences in the fermentation patterns both due to source of substrate and inoculum. It would appear that the metabolic activity of the microflora does differ significantly between adult and weanling pigs, though this varied for the different carbohydrates tested. Suggestions are made as to how to select potential carbohydrate ingredients for an in vivo experiment, based on their in vitro fermentation characteristics.
Mycorrhizal inoculation of micropropagated strawberry - case studies on mineral soil and a mined peat bog

The effects of inoculation of micropropagated strawberries `Senga Sengana' and `Jonsok with arbuscular mycorrhizal fungi at the beginning of weaning were studied in an experiment on mineral soil and mined peat soil, respectively. Despite the same sizes of inoculated and uninoculated plants at the end of weaning, AMF inoculation increased fruit yields especially on mineral soil. The experiment conducted on a mined peat bog showed less pronounced positive effects of AMF. The peat substrate caused slower spread of AMF colonization to newly formed roots. It is concluded that AMF has the potential of being included as a natural part of the micropropagation system.
Science and News: A Study of Students' Judgments of Online Scientific News Information.

This paper explores how students judge scientific news resources, as they might find through a Google search. The data were collected as part of an Institute of Museum and Library Services (IMLS) funded project. Students used a simulated search engine that ensured study participants found the same search results while seeking information for a science-related school project. The 116 students from high school, community college, undergraduate, and graduate communities evaluated three online news resources for their helpfulness, citability, credibility, and container. Analysis of quantitative data from the study indicated that students may find news resources helpful for a science project, but do not always consider them citable. Students appeared to focus on the organization that produced the news resource (i.e., source) when judging its credibility. Not all students identified the resources’ containers as news, even when the source was widely known. The researchers note differences in judgment between educational stages. Differences were especially pronounced between high school and higher education students, with high school students more likely to find news sources worthy of citing for school projects.
Genetic parameters in a Swine Population

The estimation of the variance-covariance components is a very important step in animal breeding because these components are necessary for: estimation of the genetic parameters, prediction of the breeding value and design of animal breeding programs. The estimation of genetic parameters is the first step in the development of a swine breeding program, using artificial insemination. Various procedures exist for estimation of heritability. There are three major procedures used for estimating heritability: analysis of variance (ANOVA), parents-offspring regression and restricted maximum likelihood (REML). By using ANOVA methodology or regression method it is possible to obtain aberrant values of genetic parameters (negative or over unit value of heritability coefficient, for example) which can not be interpreting because is out of biological limits.
