Zebularine is a cytidine analogue which has an ability to cause DNA demethylation in plants and many other organisms which resulted in gene reactivation and chromosome structural variations.
Oligodeoxynucleotides (oligos hereafter) are short (20～50 nt) and single stand DNA molecules which are widely used in genetic research.The use of specific oligos as probes makes FISH more rapidly and
QTL analysis of flour falling number using recombinant inbred lines derived from strong gluten wheat
Flour falling number (FN) is an important trait because of not only relating with pre-harvest sprouting (PHS) tolerance but processing quality.Waxy wheat usually has low flour falling number (FN) with

小麦穗部性状是与产量关系密切的重要农艺性状.本研究以Batavia和Erine为亲本构建的DH群体为材料,利用SSR标记和DArT标记对穗长进行数量性状进行QTL分析.构建的遗传连锁图谱由77个SSR标记和711个DArT标记组成,图谱全长1813.3 cM,标记间的平均遗传距离为2.301 cM.

High molecular weight glutenin subunits (HMW-GSs) are significant in the determination of grain processing quality.However, the diversity and variations of HMW-GSs are relatively low in bread wheat.
Chromosome translocation is an important driving force in the evolutionary process and crop breeding that can immediately change gene linkages and gene expression.

Elytrigia Desv.is one of the important perennial genera in the tribe Triticeae (Poaceae).Desvaux first established it based on Triticum repense L.in 1810 because of the strongly rhizimaous chracter, a
