Abstract

(TSWV) is one of the plant viruses transmitted by thrips and causes severe economic damage to various crops. From 2008 to 2011, to identify natural host species of TSWV in South Korea, weeds and crops were collected from 5 regions (Seosan, Yesan, Yeonggwang, Naju, and Suncheon) where TSWV occurred and were identified as 1,104 samples that belong to 144 species from 40 families. According to reverse transcription-polymerase chain reaction, TSWV was detected from 73 samples from 23 crop species, 5 of which belonged to family Solanaceae. Additionally, 42 weed species were confirmed as natural hosts of TSWV with three different life cycles, indicating that these weed species could play an important role as virus reservoirs during no cultivation periods of crops. This study provides up-to-date comprehensive information for TSWV natural hosts in South Korea.

摘要

番茄斑萎病毒（TSWV）是由蓟马传播的植物病毒之一，会给多种作物造成严重的经济损失。2008年至2011年期间，为了确定韩国番茄斑萎病毒的天然寄主物种，从番茄斑萎病毒发生的5个地区（瑞山、礼山、灵光、罗州和顺天）采集了杂草和作物，并将其鉴定为来自40个科144个物种的1104个样本。根据逆转录-聚合酶链反应，在来自23种作物的73个样本中检测到了番茄斑萎病毒，其中5种属于茄科。此外，42种杂草被确认为具有三种不同生命周期的番茄斑萎病毒天然寄主，这表明这些杂草物种在作物非种植期可能作为病毒库发挥重要作用。本研究为韩国番茄斑萎病毒的天然寄主提供了最新的综合信息。
