Abstract

Spinach is a vegetable crop which is widely grown over a large area especially in Punjab province of Pakistan. Leaf curling and enations on spinach plant collected shown to be associated with the begomovirus (PeLCV) and Shahdadpur strain of Cotton leaf curl Multan betasatellite (CLCuMB). Defective molecules of half and quarter size derived from monopartite begomoviruses are usually generated by the deletion of virion-sense sequences. Characterization of defective molecules of PeLCV from spinach revealed that the molecules of half the size are derived from the deletion of complementary-sense genes while quarter size molecule appears to have evolved by further deletion. This is the first report of the begomovirus-betasatellite complex on spinach and unusual defective molecules derived from deletion of complementary-sense genes in Pakistan.

摘要

菠菜是一种蔬菜作物，在大面积地区广泛种植，尤其是在巴基斯坦的旁遮普省。对采集到的菠菜植株上的叶片卷曲和耳突进行检测，发现其与双生病毒（辣椒曲叶病毒，PeLCV）以及棉花曲叶木尔坦病毒沙赫达德布尔株系的β卫星（CLCuMB）有关。单分体双生病毒产生的半大小和四分之一大小的缺陷分子通常是由于病毒链序列的缺失所致。对来自菠菜的PeLCV缺陷分子进行表征发现，半大小的分子源自互补链基因的缺失，而四分之一大小的分子似乎是通过进一步缺失而进化而来。这是巴基斯坦关于菠菜上双生病毒-卫星病毒复合体以及源自互补链基因缺失的异常缺陷分子的首次报道。
