摘要:
番茄花葉病毒(Tomato mosaic virus,ToMV)于1909年首次在美國(guó)報(bào)道,是一類(lèi)世界性分布的植物病毒, 能在多種作物上引起嚴(yán)重病害, 造成重大經(jīng)濟(jì)損失,ToMV的寄主范圍很廣,番茄是其主要寄主。本文利用分子生物學(xué)方法,從引起花葉的加工番茄病樣上,檢測(cè)到ToMV,在分子水平上證實(shí)ToMV存在;并且利用ToMV的單克隆抗體, 建立ELISA檢測(cè)系統(tǒng),對(duì)部分種植加工番茄地區(qū)ToMV進(jìn)行田間檢測(cè),以便弄清各加工番茄地區(qū),ToMV的發(fā)生情況,從而為加工番茄的生產(chǎn)、抗病育種和防治提供理論依據(jù)。
Abstract:
The PCR product of isolate XJ152-1 was cloned and sequenced. Sequence comparisons showed that it consisted of 690 nt, with a 480 nt open reading frame (ORF), had high sequence identities (more than 97%) with other reported ToMV and the ORF encoded CP protein. Field samples were detected by ELISA with monoclonal antibody to ToMV. The results showed that ToMV was distributed in Shihezi, Manas and Yanqi. 13 processing tomato cultivars were also detected by ELISA in field for Evaluation of disease resistance to ToMV. The results demonstrated that none of them was resistant to ToMV and 2 were susceptible.
Key words: processing tomato;molecular identification; serological test
