摘要
山药(Dioscorea oppositifolia),又名薯蓣、山薯、大薯,属薯蓣科(Dioscoreaceae)薯蓣属(Dioscorea)藤本植物,其块茎富含蛋白质、淀粉、多糖、矿物质等营养元素,可作为药用或食用材料。大多数山药块茎为一年生,部分山药的块茎逐年增大并木质化形成地下茎。贵州安顺山药种植已有300年的历史,已获全国农产品地理标志。随着安顺山药种植规模的扩大,长期留种出现病毒累积、品种退化的现象。
Anshun is the main producing area of yam(Dioscorea oppositifolia)in Guizhou Province.Recently,field investigations found that yam in Anshun area was suspected to be infected with cucurbit chlorotic yellows virus(CCYV),which caused huge economic losses to local farmers.The leaves suspected of being infected with CCYV were collected.RT-PCR detection was performed on the suspected diseased leaf samples,and CCYV was determined in combination with the sequencing results.Phylogenetic analysis was performed by CCYV coat protein(CP)sequence.The results showed that the isolates detected by Anshun in Guizhou had small regional differences with the isolates in USA and Saudi Arabia and other countries,and the relatives were relatively close,while the isolates in Iran was relatively distant.The findings will facilitate further research and help develop strategies for the prevention and control of CCYV in yam.
