Cucurbit chlorotic yellows virus (CCYV) and cucurbit yellow stunting disorder (CYSDV) are two closely related criniviruses that often coinfect cucurbits associated with disease. Both viruses distributed worldwide transmitted in a semipersistent manner by the whitefly vectors Bemisia tabaci MED or MEAM1. The major goal of this study was to provide insight into interaction CCYV CYSDV cucumber eff...
A fluorescent viral clone of the polerovirus Turnip yellows virus (TuYV) was engineered by introducing the Enhanced Green Fluorescent Protein (EGFP) sequence into the non-structural domain sequence of the readthrough protein, a minor capsid protein. The resulting recombinant virus, referred to as TuYV-RTGFP, was infectious in several plant species when delivered by agroinoculation and invaded e...
تعداد زیادی از ویروس‌های گیاهی قابل انتقال توسط سفید بالک‌ها همراه و یا دخیل در نشانه‌های زردی از مزارع و یا گلـخانه‌های خیار در دنیا گزارش شده‌اند. در سال‌های اخیر، نشانه‌های زردی و جمعیت‌های زیادی از سفید بالک‌ها در بسیاری از گلخـانه‌های خیار در ایران مشاهده گردیده است. در این تحقیق در سال‌های 90 و 91، تعداد 287 نمونه برگ خیار با نشانه‌های زردی و تردی برگ‌ها از گلخانه‌های خیار در استان‌های ته...
The cucurbits belong to the family Cucurbitaceous (gourd family) under order Cucurbit ales which include many economically important vegetable and fruit species. Among various factors, viruses are one of factors reducing in quantity as well quality cucurbits. These crops severely affected by cucurbit mosaic disease worldwide, is major viral Considering importance disease, present investigation ...
Cucurbit chlorotic yellows virus (CCYV) (genus Crinivirus, family Closteroviridae) is an emerging plant virus, and is now spreading and causing severe economic losses to cucurbit crops in many Asian countries. CCYV is believed to be transmitted specifically by the sweetpotato whitefly, Bemisia tabaci, in a semipersistent manner. In the present study, we provide direct evidence for the semipersi...
