Development of a Set of Wheat-Rye Derivative Lines from Hexaploid Triticale with Complex Chromosomal Rearrangements to Improve Disease Resistance, Agronomic and Quality Traits of Wheat [PDF]

Plants, 2023
An elite hexaploid triticale Yukuri from Australia was used as a bridge for transferring valuable genes from Secale cereale L. into common wheat for enriching the genetic variability of cultivated wheat. Non-denaturing-fluorescence in situ hybridization (

Molecular and cytogenetic dissection of stripe rust resistance gene Yr83 from rye 6R and generation of resistant germplasm in wheat breeding [PDF]

Frontiers in Plant Science, 2022
Rye 6R-derived stripe rust resistance gene Yr83 in wheat background was physically mapped to fraction length (FL) 0.87-1.00 on the long arm by non-denaturing-fluorescence in situ hybridization (ND-FISH), Oligo-FISH painting and 6R-specific PCR markers ...

Physical Mapping of a Powdery Mildew Resistance Gene in Chromosome 6St from Wheat-Thinopyrum intermedium Introgression Lines [PDF]

Plants
Powdery mildew, caused by Blumeria graminis f. sp. tritici, is a devastating disease threatening global wheat production. Thinopyrum intermedium, a wild relative of wheat, harbors valuable resistance genes for wheat improvement.

Cross-species chromosome painting offers new insights into the phylogenetic relationships among 16 representative species of Ipomoeeae [PDF]

Frontiers in Plant Science
IntroductionPrevious phylogenetic studies of Ipomoeeae species have shown inconsistent results, and latest molecular analyses have classified this tribe into two major clades (Argyreiinae and Astripomoeinae) comprising seven smaller clades.

Characterization of a New Stripe Rust Resistance Gene on Chromosome 2StS from Thinopyrum intermedium in Wheat [PDF]

Plants
Stripe rust, caused by Puccinia striiformis f. sp. tritici, is a highly destructive disease prevalent across most wheat-growing regions globally. The most effective strategy for combating this disease is through the exploitation of durable and robust ...

A universal karyotypic system for hexaploid and diploid Avena species brings oat cytogenetics into the genomics era

BMC Plant Biology, 2021
Background The identification of chromosomes among Avena species have been studied by C-banding and in situ hybridization. However, the complicated results from several cytogenetic nomenclatures for identifying oat chromosomes are often contradictory.
