Comparisons in genetic diversity suggested that continental lineages display higher levels of genetic diversity and differentiation from their island relatives, and the low degree of genetic diversity and differentiation within an island suffered from bottlenecks related to founder effects.

Wheat leaf rust caused by Puccinia triticina is one of the important diseases of wheat in China.It can cause a pandemic in a short time and cause yield losses of 5% to 45% or more on susceptible wheat
Yangmai 18, a new soft wheat variety with high powdery mildew resistance, was developed following the rolling convergent backcross procedure with the resistant donor as T6VS.6AL translocation that con
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
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

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.
