Over the last decade, the significance of yellow rust caused by () has substantially increased worldwide, including in Russia. The development and cultivation of resistant genotypes is the most efficient control method. The present study was conducted to explore the yellow rust resistance potential of modern common winter wheat cultivars included in the Russian Register of Breeding Achievements in 2019-2022 using the seedling tests with an array of races and molecular markers linked with resistance genes. Seventy-two winter wheat cultivars were inoculated with five isolates differing in virulence and origin. Molecular markers were used to identify genes , , , , , , , , , and . Thirteen cultivars were resistant to all isolates. The genes , , and that are effective against all Russian races in resistant cultivars were not found. Using molecular methods, gene located in translocation 1BL.1RS was detected in 12 cultivars, gene in 24, gene in 3 and 1AL.1RS translocation with unknown gene in 2. While these genes have lost effectiveness individually, they can still enhance genetic diversity and overall yellow rust resistance, whether used in combination with each other or alongside other genes.

High-quality genome information is essential for efficiently deciphering and improving crop traits. Here we report a highly contiguous and accurate hexaploid genome assembly for the key wheat breeding parent Zhou8425B, an elite 1BL/1RS translocation line with durable adult plant resistance (APR) against yellow rust (YR) disease. By integrating HiFi and Hi-C sequencing reads, a 14.

Following an episode of sudden lethargy, an 18-month-old female black-capped parrot (Pionites melanocephalus) died while being examined. On gross examination, there was fluid within the coelom, hepatomegaly with yellow colouration and the heart appeared enlarged with pallor throughout the myocardium. On histological examination, cardiomyocytes were swollen with loss of cross striations and contained 6-12-μm diameter intrasarcoplasmic pale grey inclusions of storage material.

Triticale (× Triticosecale), was initially produced by crossing wheat (Triticum) with rye (Secale). Although still a minor crop in Canada, triticale grain is used both as human food (in bread, pastry products, and the brewing industry) and as livestock feed (Larter 2015). In September 2023 typical leaf rust samples were observed and collected in winter Triticale at Lacombe, Alberta.

Background: Yellow (stripe) rust of wheat, caused by Puccinia striiformis, is a serious disease that results in great economic losses. This study aimed to investigate the variation in plant responses in three wheat cultivars with different resistance levels against yellow rust.
Results: The highest disease severity was recorded for cv.
