陕西省是我国苹果种植大省,苹果锈果病的发生严重影响其苹果产业,该病是由苹果锈果类病毒(Apple scar skin viroid,ASSVd)引起的,陈炜和田波(1985)首次在国内发现了ASSVd的RNA,Hashimoto&Koganezawa(1987)首次报道了ASSVd的全基因组序列。郭瑞等(2005)报道了我国ASSVd辽宁和新疆苹果分离物的序列,郝璐等(2015)发现ASS-
Shaanxi Province is a major apple-growing province in China. The occurrence of apple rust caused serious impact on the apple industry. The disease is caused by Apple scar skin viroid (ASSVd). Chen Wei and Tian Bo (1985) ASSVd RNA was discovered in China, and the genome-wide sequence of ASSVd was first reported by Hashimoto & Koganezawa (1987). Guo Rui et al (2005) reported the sequences of ASSVd apple isolates from Liaoning and Xinjiang. Hao et al. (2015) found that ASS-
