Abstract:
... Wheat stripe rust, caused by Puccinia striiformis tritici (Pst), is a widespread disease of wheat, and causing significant losses in yield. Twenty-five races were identified from 160 samples in greenhouse tests. Samples were collected from wheat fields in governorates; Kafrelsheikh, Al-Sharqia, Dakahlia and Gharbia were tested. The most important commercial wheat cultivars, i.e. Misr1, Misr2, Giza ...

Abstract:
... Fungal pathogens secrete effector molecules into host plant cells to suppress host immunity to colonize plants. Ongoing efforts are being made to identify and characterize effector proteins in many fungal plant pathogens. Nevertheless, the precise biological and biochemical functions of many effectors, such as their trafficking from the pathogen to the host, have yet to be fully understood. In thi ...
