Fourteen isolates of Rice yellow mottle virus (RYMV) were selected as representative of the genetic variability of the virus in Africa from a total set of 320 isolates serologically typed or partially sequenced. The 14 isolates were fully sequenced and analyzed together with two previously reported sequences. RYMV had a genomic organization similar to that of Cocksfoot mottle sobemovirus. The a...
Biological invasions are the main causes of emerging viral diseases and they favour the co-occurrence of multiple species or strains in the same environment. Depending on the nature of the interaction, co-occurrence can lead to competitive exclusion or coexistence. The successive fortuitous introductions of two strains of Tomato yellow leaf curl virus (TYLCV-Mld and TYLCV-IL) in Réunion Island ...
Early diagnosis of plant virus infections before the disease symptoms appearance may represent a significant benefit in limiting disease spread by a prompt application of appropriate containment steps. We propose a label-free procedure applied on a device structure where the electrical signal transduction is evaluated via impedance spectroscopy techniques. The device consists of a droplet suspe...
در بهار سال 1390 طی بازدیدی از مراکز تولید گیاهان زینتی در شهرستان های کرج و تنکابن، تعدادی بوته هوستا (hosta sieboldiana.) با علائم موزائیک، پیسک و بدشکلی برگ ها مشاهده شد. تعداد 17 بوته علائم دار انتخاب شد و احتمال آلودگی آنها به ویروس های موزائیک آرابیس (arabis mosaic virus-armv)، موزائیک خیار (cucumber mosaic virus-cmv)، پژمردگی لکه ای گوجه فرنگی (tomato spotted wilt virus-tswv)، لکه نکروز ...
Persistent circulative transmission of plant viruses involves complex interactions between the transmitted virus and its insect vector. Several studies have shown that insect vector proteins are involved in the passage and the transmission of the virus. Interestingly, proteins expressed by bacterial endosymbionts that reside in the insect vector, were also shown to influence the transmission of...
