Drought is one of the major environmental constraints for wheat production world-wide. As progenitor and genetic reservoir common wheat, emmer considered as an invaluable gene pool breeding drought-tolerant wheat. Combining GWAS eGWAS analysis 107 accessions, we identified 86 QTLs, 105 462 eQTLs well 68 eQTL hotspots associating with drought tolerance (DT) in A complex regulatory network composed 185 upstream regulator 2432 downstream drought-responsive candidates was developed, which TtOTS1...
Thinopyrum ponticum (2n = 10x 70, EeEeEbEbExExStStStSt), a wild relative of common wheat (Triticum aestivum L., 2n 6x 42), possesses extensive genetic diversity. The primary objective this study was to develop and evaluate alien derivatives carrying the St-chromosome from Th. ponticum, aiming improve disease resistance agronomic traits. In study, set developed ponticum. Chromosomal compositions, karyotypes homoeologous group affiliations seven were characterized using genomic in situ...
Abstract Background Developing novel germplasm by using wheat wild related species is an effective way to rebuild the resource bank. The Psathyrostachys huashanica Keng ( P. , 2 n = x 14, NsNs) regarded as a superior improve breeding because of its multi-resistance, early maturation and numerous tiller traits. Introducing genetic components into common background most important step in achieving use. Therefore, cytogenetic characterization influence introgressed large segment chromosomes...
Wheat (Triticum aestivum L.) is one of the most important cereal crops worldwide, and its production challenged by global climate change a shortage resources. The root system plays vital role in uptaking water nutrients sensing soil environmental signals, it has great potential to improve final yield stress tolerance wheat. In order further explore genes regulating development, this study focused on qRS-6D, located chromosome 6D spanning from 462,701,391 465,068,943, which was significantly...
Alternative splicing (AS) is a gene regulatory mechanism that generates multiple transcripts of the same precursor by spliceosome complex, promoting messenger RNA complexity, and proteome diversity. Although AS extensively studied in response to environmental stresses, whether it mediates age-dependent development how adjusted growth transitions are largely unknown. Here, we comprehensively explored landscape at different developmental stages grass model plant Brachypodium (Brachypodium...

Selenium rich bread is a good carrier of selenium, but the inorganic selenium used in actual production process toxic. It necessary to develop new green technology. The extraction and utilization humic acid chelated from selenium-rich soil beneficial for reducing resource waste pollution without destroying ecosystem selenium-deficient areas. Sodium selenite nanoselenium were selected as controls because they are commonly agronomic enhancers production.Humic can be absorbed accumulated by...
Abstract Thinopyrum species are an important source for new genetic variation wheat improvement because they carry many agronomically traits, such as abiotic/biotic resistances. Accurate identification of exogenous chromosome(s) or chromosome segments genes is very after alien material has been successfully introduced into wheat, but remains challenging. Here, we report the development a high-resolution wheat-Thinopyrum elongatum array, named GenoBaits®WheatplusEE, to trace information...
SNARE (Soluble N - ethylmaleimide sensitive factor attachment protein receptor) proteins are mainly mediated eukaryotic cell membrane fusion of vesicles transportation, also play an important role in plant resistance to fungal infection. In this study, 1342 were identified 18 plants. According the reported research, it was splited into 5 subfamilies (Qa, Qb, Qc, Qb+Qc and R) 21 classes. The number SYP1 small classes Qa is largest (227), smallest (67). Secondly, through analysis phylogenetic...
