The SGT1 protein is essential for R protein-mediated and PAMPs-triggered resistance in many plant species. Here we reported the isolation and characterization of the Hv-SGT1 gene from Haynaldiavillosa (2n = 14, VV). Analysis of the subcellular location of Hv-SGT1 by transient expression of a fusion to GFP indicated its presence in the cytoplasm and nucleus.(More)
Wild relatives of wheat possess many agronomic traits important to wheat improvement. Wheat–alien translocation and deletion lines are important genetic stocks in wheat breeding or physical mapping of important alien genes. However, screening for chromosomal structural changes by conventional cytogenetic analyses is time-consuming work. It is necessary to(More)
Stripe rust, caused by Puccinia striiformis f. sp. tritici (Pst), is one of the most serious diseases of wheat; therefore, exploring effective resistance-related genes is critical for breeding and studying resistance mechanisms. However, only a few stripe rust resistance genes and defence-related genes have been cloned. Moreover, transgenic wheat with(More)
The powdery mildew resistance gene Pm21 was physically and comparatively mapped by newly developed markers. Seven candidate genes were verified to be required for Pm21 -mediated resistance to wheat powdery mildew. Pm21, a gene derived from wheat wild relative Dasypyrum villosum, has been transferred into common wheat and widely utilized in wheat resistance(More)
The stripe rust resistance gene, Yr26, is commonly used in wheat production. Identification of Yr26 resistance related genes is important for better understanding of the resistance mechanism. TaRab18, a putative small GTP-binding protein, was screened as a resistance regulated gene as it showed differential expression between the Yr26-containing resistant(More)

Wheat-Haynaldia villosa translocations T6V#2S.6AL and T6V#4S.6DL, carriers of Pm21 and PmV, respectively, continue to contribute powdery mildew resistance in wheat varieties in China. Based on colinearity between Brachypodium distachyon and Triticeae species, genomic sequences from gene intervals of B. distachyon physically linked to a homolog of Stpk-V, a(More)
