Characterization and functional analysis of the differentially expressed genes in the Bgt-inoculated
Differential gene expression after Blumeria graminis f.sp Tritici(Bgt) was compared in wheat near-isogenic line (NILs) differing powdery mildew resistance gene.
CEL Ⅰ-based TILLING (Targeting Induced Local Lesions IN Genomes) platform is very useful for high throughput identification of point mutations within targeted genes and improvement of mutation-detecte
Abiotic stresses such as drought, salinity, and cold have significantly influence on plant growth and development.Protein phosphorylation/dephosphorylation are major events that mediating acclimation
Ionizing irradiation (IR) can produce clustered DNA damages, particularly double-strand DNA breaks (DSBs) in the organism.Ku protein is of central importance to DNA damage-repair and responses to IR i
In this study, a wheat mutant library with EMS was constructed for laying a foundation for wheat drought resistance research.EMS was used as chemical mutagen to build the mutant library with wheat cul
Rapid advances in next-generation sequencing technology have provided new opportunities to the field of RNA sequencing (RNA-Seq).The unprecedented sequencing depth provided by RNA-Seq makes it a power
A wheat bZIP transcription factor, TabZIP1-D, confers drought and salt tolerances in transgenic Arab
The bZIP proteins are involved in various processes of plant growth, development and stress.In this study, we cloned a TabZIP1-D transcription factor and isolated its genome sequence of TabZIP1-D from
Brachypodium distachyon is a member of the Poaceae subfamily Pooideae and has emerged as a model species for the study of cool season cereal crops (barley, wheat, oats and rye).
It is crucial in discovering genes associated with wheat yield and quality traits by studying the grain developmental process and resolving the regulatory mechanism of grain development.
详细了解我国目前不同地区大面积种植及新培育小麦品种的遗传多样性,对于认识小麦优良基因、指导小麦亲本选配具有重要意义,在小麦杂交育种有着重要参考价值.本研究利用均匀分布于21条染色体的80对SSR标记,对266份近年来不同地区大面积推广种植的优良小麦品种以及杂交后代进行遗传多样性分析.
