Durable disease resistance genes such as the wheat gene Lr34 are valuable sources of for agricultural breeding programs. encodes an ATP-binding cassette transporter protein involved in transport phytohormone abscisic acid. from is functionally transferable to barley, maize, rice and sorghum. A pleiotropic effect induces development a senescence-like phenotype, referred leaf tip necrosis. We use...

been widely used to characterize foliar disease resistance (Jeger and Viljanen-Rollinson, 2001) because it Slow leaf-rusting resistance in wheat (Triticum aestivum L) is gainreflects both severity and rate of disease development ing acceptance as a breeding objective because of its durability in comparison with race-specific resistance. CI 13227 was previously (Wilcoxson et al., 1975). IR and I...

Leaf rust, caused by Puccinia triticina Eriks., is a common and widespread disease of wheat (Triticum aestivum L.) in Egypt. Host resistance is the most economical, effective, and ecologically sustainable method of controlling the disease. Molecular markers help to determine leaf rust resistance genes (Lr genes). The objective of this study was to identify Lr genes in fifteen wheat cultivars fr...

Background. Information on the races of Puccinia triticina Erikss. in Novosibirsk Province is needed to identify sources effective genes for leaf rust resistance. The goal hereof was monitoring genetic variability P. population Ob riverside forest-steppe, Province, and detecting resistance develop wheat cultivars resistant disease. Materials methods. In 2015–2019, affliction Thatcher lines (Tc)...

Recently we cloned and characterized the gene for the wheat transcription factor TaWRKY45 and showed that TaWRKY45 was upregulated in response to benzothiadiazole (BTH) and Fusarium head blight (FHB) and that its overexpression conferred enhanced resistance against F. graminearum. To characterize the functional role of TaWRKY45 in the disease resistance of wheat, in the present study we conduct...
