Brief Note: Natural infection of Viola cornuta (Violaceae) with Cucumber mosaic virus, subgroup I

Natural infection of Viola cornuta (Violaceae) with Cucumber mosaic virus, subgroup I.

Plants of Viola cornuta displaying typical virus symptoms were observed during spring 2003 in a plant nursery in Córdoba, central Argentina. Electron microscopic examinations of symptomatic leaf samples revealed the presence of isometric virus-like particles about 30 nm in diameter. Subsequent serological analysis allowed the identification of the pathogen as a subgroup I strain of Cucumber mos...

حذف ویروس موزاییک خیار (cucumber mosaic virus, cmv) از گلایل

ویروس موزاییک خیار از رایج‎ترین ویروس‎های گلایل در سراسر جهان است. تکثیر گلایل از طریق اندام رویشی پداژه است بنابراین بیماری‎های ویروسی در آن از نسلی به نسل بعد منتقل و سبب افزایش بیماری و کاهش کیفیت آن می‎شود. بنابراین تولید پداژه‎های سالم از اهمیت زیادی برخوردار است. در این تحقیق درصد آلودگی پداژه‎های گلایل موجود در بازار به ویروس موزاییک خیار در دو استان تهران و البرز تعیین شد و روش گرمادرما...

Infection of tobacco mesophyll protoplasts by cucumber mosaic virus.

Protoplasts isolated from tobacco leaves were inoculated with cucumber mosaic virus (CMV) using a method slightly modified from that developed for inoculating tobacco mosaic virus. Multiplication of CMV was demonstrated by staining the protoplasm with fluorescent CMV-antibody, by the electron microscopy of ultrathin sections, and by assaying the infectivity in protoplasts. Seventy to 90% of pro...
