Journal ArticleDOI
A novel Robertsonian translocation event leads to transfer of a stem rust resistance gene (Sr52) effective against race Ug99 from Dasypyrum villosum into bread wheat
L. L. Qi,Michael O. Pumphrey,Bernd Friebe,Peng Zhang,C. Qian,Robert L. Bowden,Matthew N. Rouse,Yue Jin,Bikram S. Gill +8 more
TL;DR: The T6AS·6V#3L stock is a new source of resistance to Ug99, is cytogenetically stable, and may be useful in wheat improvement.
Journal ArticleDOI
An innovative SNP genotyping method adapting to multiple platforms and throughputs
TL;DR: A novel SNP genotyping method designated as semi-thermal asymmetric reverse PCR (STARP), which endowed STARP with all the major advantages of high accuracy, flexible throughputs, simple assay design, low operational costs, and platform compatibility.
Journal ArticleDOI
De novo sequencing of sunflower genome for SNP discovery using RAD (Restriction site Associated DNA) approach.
TL;DR: This report reports on the process of SNP discovery through reductive genome sequencing and local assembly of six diverse sunflower inbred lines that represent oil as well as confection types, offering an attractive tool for molecular breeding purposes in sunflower.
Journal ArticleDOI
A high-density SNP Map of sunflower derived from RAD-sequencing facilitating fine-mapping of the rust resistance gene R12.
Zahirul I. Talukder,Li Gong,Brent S. Hulke,Venkatramana Pegadaraju,Qijian Song,Quentin Schultz,L. L. Qi +6 more
TL;DR: A high-resolution genetic map of sunflower was constructed by integrating SNP data from three F2 mapping populations, providing closely linked SNP markers for marker-assisted selection of the rust resistance gene R12 and showing high levels of collinearity among individual maps.
Journal ArticleDOI
Molecular cytogenetic analysis of Leymus racemosus chromosomes added to wheat
TL;DR: The study presented here provides the first evidence of homoeology of the added L. racemosus chromosomes with wheat chromosomes using DNA markers and provides the basis for further directed chromosome engineering aimed at producing compensating wheat-L.
