The amount and distribution of genetic variation in Phytophthora infestans populations is one of the key factors influencing the occurrence and epidemic of potato late blight.
由链格孢菌(Alternaria alternata)引起的柑橘褐斑病(Alternaria brown spot,ABS)是一种严重的真菌病害,近年来在我国柑橘主产区迅速蔓延,造成巨大的经济损失。目前,国内外已经相继开展病原菌分离鉴定、生物学特性、侵染机制、品种抗性及病害流行发生规律等试验且取得一定成果。
The genetic diversity of ATP synthase F0 subunit 6 (ATP6) in Phytophthora infestans was analyzed by sequencing 139 isolates sampled from potato from seven groups of six parts of Chi-na.
In oomycete Phytophthora infestans,the causal agent of late blight disease of potato and tomato,four double-stranded RNAs (dsRNAs),namely P.infestans RNA virus 1 to 4 (PiRV-1 to PiRV-4) have been repo
The genetic basis of pathogen adaptation to hosts is a critical issue of molecular evolu-tion.β-glucosidases (BGLUs;EC 3.2.1.21) could hydrolyze cellobiose to two molecules of glucose monomers.
