Summary of "Identification, Characterization, and Evaluation of Novel Stripe Rust-Resistant Wheat- Chromosome Translocation Lines."

Stripe rust is an important disease in wheat, and development of genetic resistance in cultivars is an effective approach to control the disease. Wild species of wheat, such as , are an excellent gene source for wheat improvement. In this study, two stripe rust-resistant wheat- chromosome translocation lines, CH4131 and CH4132, were characterized by cytogenetic and pathological methods. The introgressed chromosome fragment was tagged using amplified fragment-length polymorphism-derived sequence-characterized amplified region (SCAR) markers and intron targeting markers, indicating that CH4131 and CH4132 both possess a homologous group 3 chromatin of . Genomic in situ hybridization results suggested that a very small chromosome segment was translocated to the terminal region of wheat 1BS for both lines, forming a configuration of T3Ai-1BS.1BL. The two translocation lines were resistant to stripe rust, and the resistance gene, temporarily designated , was likely derived from . The translocated chromosome fragments have no genetic linkage drag to agronomic performance. The grain quality indexes of these two translocations were higher than local wheat varieties. Therefore, CH4131 and CH4132 could be used as potential gene sources in wheat improvement programs. The SCAR markers are useful to select stripe rust resistance from .

Medical and Biotech [MESH] Definitions

Allergic reaction to wheat that is triggered by the immune system.

A plant genus of the family POACEAE that is the source of wheat grain. A hybrid with rye (SECALE CEREALE) is called TRITICALE. The seed is ground into FLOUR and used to make BREAD, and is the source of WHEAT GERM AGGLUTININS.

Lectins purified from the germinating seeds of common wheat (Triticum vulgare); these bind to certain carbohydrate moieties on cell surface glycoproteins and are used to identify certain cell populations and inhibit or promote some immunological or physiological activities. There are at least two isoforms of this lectin.

A diet which is devoid of GLUTENS from WHEAT; BARLEY; RYE; and other wheat-related varieties. The diet is designed to reduce exposure to those proteins in gluten that trigger INFLAMMATION of the small intestinal mucosa in patients with CELIAC DISEASE.

Strains of the genus Enterococcus that are resistant to the antibiotic VANCOMYCIN. The enterococci become resistant by acquiring plasmids carrying genes for VANCOMYCIN RESISTANCE.
