"The present project evaluated the feasibility of producing shikimic acid (SA) and phenolic compounds (PC) in wounded carrots (Daucus carota) treated with glyphosate. The spray application of a concentrated glyphosate solution on wounded carrot tissue increased the concentrations of SA and chlorogenic acid by 1735 and 5700%, respectively."
"Cycles of whole genome duplication (WGD) and diploidization are hallmarks of eukaryotic genome evolution and speciation. Polyploid wheat (Triticum aestivum) has had a massive increase in genome size largely due to recent WGDs. How these processes may impact the dynamics of gene evolution was studied by comparing the patterns of gene structure changes, alternative splicing (AS), and codon substitution rates among wheat and the model grass genomes."
"The number of associations detected per trait varied, according to the way the structure was taken into account, with 0–41 associations detected per trait in the whole collection and a maximum of four associations in the S. lycopersicum var. cerasiforme accessions. A total of 40 associations (30 %) were co-localized with previously identified quantitative trait loci. This study thus showed the potential and limits of using association mapping in tomato populations."
"One of the central questions in the development of Mesoamerican civilization is how the alimentary, agronomic, and ecological complementarities were achieved within the milpa agroecosystem, which is one of its more important and distinctive cultural elements."
"Altmetrics may support finer-grained maps of science, broader and more equitable evaluations, and improvements to the peer-review system . On the other hand, the use and development of altmetrics should be pursued with appropriate scientific caution. Altmetrics may face attempts at manipulation similar to what Google must deal with in web search ranking. Addressing such manipulation may, in-turn, impact the transparency of altmetrics. New and complex measures may distort our picture of the science system if not rigorously assessed and correctly understood. Finally, altmetrics may promote an evaluation system for scholarship that many argue has become overly focused on metrics."
"Our study yielded a large number of single nucleotide polymorphisms as well as estimates of gene expression on transcriptome scale. In agreement with a recent study we find that the synonymous substitution rate per year (0.6 x 10-09 and 1.1 x 10-09) is an order of magnitude smaller than values reported for angiosperm herbs. However, if one takes generation time into account, most of this difference disappears. The estimates of the dN/dS ratio (non-synonymous over synonymous divergence) reported here are in general much lower than 1 and only a few genes showed a ratio larger than 1."
"Our results show that A. tumefaciens-mediated PITGS can be used as a reverse genetics tool to discover gene function in rust fungi. This proof-of-concept study indicates that the targeted fungal transcripts might be important in pathogenesis and could potentially be utilized as promising targets for developing RNA interference-based resistance against rust fungi."
"These results demonstrate that a few QTLs with major effects and several QTLs with medium to minor effects might contribute to the natural variation of tocopherols in maize grain. The high-density markers will help to fine map and identify the QTLs with major effects even in the preliminary segregating populations. Furthermore, this study provides a simple guide line for the breeders to improve traits that minimize the risk of malnutrition, especially in developing countries."
"We assessed the structure of the microbiome associated to the drought-sensitive pepper plant (Capsicum annuum L.) cultivated in a traditional Egyptian farm, focusing on microbe contribution to a crucial ecosystem service, i.e. plant growth under water deficit."
"Until now, the availability of vectors for transgenic research in cereal crops has been rather limited. We present a novel collection of Agrobacterium tumefaciens binary T-DNA vectors compatible with Gateway recombinational cloning that facilitate the modular assembly of genes of interest together with new regulatory sequences, such as strong constitutive or endosperm-specific Brachypodium distachyon promoters. This resource aims at streamlining the creation of vectors and transgenes designed to explore gene functions in vital monocotyledonous crops"
"High throughput assays were developed for SNPs that delimit the physical intervals of these mQTL. At most of the QTL, almost equal number of favorable alleles was donated by either of the parents within each cross, thereby demonstrating the potential of drought tolerant × drought tolerant crosses to identify QTL under contrasting water regimes."
"Gender-based violence (GBV) transcends borders, social status, wealth ranking, socio-cultural background, religion, level of education, and age. It exists in every society and in every country in the world. Many of us working in international development consider GBV to be solely a health issue. Unfortunately, this is a dangerous assumption."
"PhenoPhyte is a new cost-effective web-application for semi-automated quantification of two-dimensional traits from digital imagery using an easy imaging protocol. This tool's usefulness is demonstrated for a variety of traits in multiple species. We show that digital phenotyping can reduce human subjectivity in trait quantification, thereby increasing accuracy and improving precision, which are crucial for differentiating and quantifying subtle phenotypic variation and understanding gene function and/or treatment effects."
"We conclude that combining genetic modification with mixed cropping techniques could be a promising approach to increase sustainability and productivity in agricultural systems, as the fitness cost of stacking transgenes within individuals may thus be avoided.
"Results presented here indicate that allele r(2997) of yellow-flesh eliminates transcription of PSY1 in fruits. In a genetic background of tangerine, transcription of PSY1 is partially restored to a level sufficient for producing phytoene and downstream carotenoids. Our results revealed the molecular mechanism underlying the epistasis of t over r and suggest the involvement of cis-carotenoid metabolites in a feedback regulation of PSY1 gene expression."
"The glucosinolates in seeds were significantly higher than in sprouts, and day 8 of germination was considered the optimum for consumption. The sprouts with higher concentrations of glucosinolates in 8-day-old sprouts were white mustard, turnip, and kohlrabi (815, 766, and 653 mg 100 g–1 FW, respectively). Red cabbage and radish presented great total glucosinolates content (516 and 297 mg 100 g–1 FW, respectively, in 8-day-old sprouts) and also higher total phenolic contents, biomass, and antioxidant capacity. The selection of the best performers in terms of germination quality and phytochemical composition is the key to optimize new fresh foods enriched in health-bioactive compounds."
"The results obtained are consistent with previous findings in wheat and suggest that Ggpps1, Zds and Hyd3 on chromosome 2Hch may be considered candidate genes in wheat for further studies in YPC improvement. Considering the syntenic location of carotenoid genes in H. chilense, we have concluded that the Hch genome may constitute a valuable tool for YPC studies in the Triticeae."
