A family of sequences resembling Gypsy retroelements was identified and shown to be widely distributed throughout the genus Phytophthora, a member of the algallike oomycete fungi. Polymerase chain reaction (PCR) using specific and degenerate primers detected the family in 29 of 37 species tested. DNA hybridization also failed to detect the sequences in the eight species that were negative in PC...

The late blight caused by Phytophthora infestans (P. infestans) has been a major constraint for worldwide sustainable potato production. Chinese cultivar Qingshu 9 shown excellent field performance against blight. To understand the mechanism underlying its resistance, transcriptomic dynamics of infected with P. was systematically investigated to identify resistance-related genes. In total, 2027...

In vitro dose responses of several calcium and potassium salts were determined on some commercially significant plant pathogens, including: Helminthosporium solani, Fusarium oxysporum f. sp. pisi race 2, Colletotricum coccodes, Phytophthora cactorum, Phytophthora cinnamomi, Phytophthora erythroseptica, Phytophthora infestans, Phytophthora megasperma, Pythium ultimum, and Venturia inaequalis. My...
