Host resistance responses against Puccinia striiformis f. sp. tritici in wheat cultivars with different resistance levels: molecular, biochemical, and ultrastructural studies.

ABSTRACT:

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. Gemmieza-11 (95%), followed by cv. Shandweel 1 (60%), while the lowest was recorded for cv. Misr-3 (3%). qPCR results of the yellow rust-resistance genes Yr5, Yr10, Yr15, and Yr18 showed that the infection did not affect the expression of Yr5 and Yr15 in the infected Gemmieza-11 plants when compared to the non-infected control. In contrast, the infection significantly overexpressed Yr5 and Yr15 in cvs. Shandweel 1 and Misr-3. However, Misr-3 was
