Abstract

Potato spindle tuber viroid (PSTVd; genus Pospiviroid) was detected from pepper (Capsicum annuum) seeds produced in Vietnam during an export inspection. The PSTVd isolate (PSTVd-VN) maintained its viability. The phylogenetic relationship between PSTVd-VN and other PSTVd variants that were isolated from other plants and was classified into lethal and severe strains. PSTVd-VN in tomatoes (cv. Rutgers) caused severe stunting and necrosis of the stems and leaf veins, but no symptoms in inoculated pepper plants except that the fruits were smaller than the control peppers. To our knowledge, this is the first report of PSTVd from pepper seeds produced in Vietnam.

首次报告从越南生产的辣椒种子中分离出马铃薯纺锤形块茎病毒
摘要 在一次出口检查中,从越南生产的辣椒(Capsicum annuum)种子中检测到了马铃薯纺锤形块茎病毒(PSTVd;Pospiviroid 属)。PSTVd 分离物(PSTVd-VN)保持了其活力。PSTVd-VN 与从其他植物中分离出的其他 PSTVd 变种之间存在系统发育关系,并被分为致死株和严重株。PSTVd-VN 在西红柿(cv. Rutgers)中会导致茎和叶脉严重发育不良和坏死,但在接种的辣椒植株中除果实比对照辣椒小外没有其他症状。据我们所知,这是越南生产的辣椒种子首次报告 PSTVd。
