تعیین برخی خصوصیات بیولوژیکی و مولکولی potato leafroll virus و potato virus a در استان اصفهان
چکیده سیب زمینی یکی از مهم ترین محصولات زراعی در جهان می باشد. ویروس های متعددی این گیاه را تحت تاثیر قرار می دهند و باعث خسارت اقتصادی قابل توجهی می شوند. ویروس پیچیدگی برگ سیب زمینی potato leafroll virus (plrv) عضو تیپ جنس polerovirus و خانواده luteoviridae و ویروس ای سیب زمینی potato virus a (pva) عضو تیپ جنس potyvirus از خانواده potyviridae شایع ترین ویروس های سیب زمینی می باشند که توسط ش...
15 صفحه اولEndosymbiotic bacteria associated with circulative transmission of potato leafroll virus by Myzus persicae.
In order to understand the molecular mechanisms underlying circulative transmission of potato leafroll virus (PLRV) by aphids, we screened Myzus persicae proteins as putative PLRV binding molecules using a virus overlay assay of protein blots. In this way, we found that purified PLRV particles exhibited affinity for five aphid proteins. The one most readily detected has an M(r) of 63K, and was ...
متن کاملThe passage of Potato leafroll virus through Myzus persicae gut membrane regulates transmission efficiency.
Potato leafroll virus (PLRV) is transmitted by aphids in a persistent manner. Although virus circulation within the aphid leading to transmission has been well characterized, the mechanisms involved in virus recognition at aphid membranes are still poorly understood. One isolate in our collection (PLRV-14.2) has been shown to be non- or only poorly transmitted by some clones of aphids belonging...
متن کاملPoint mutations in the potato leafroll virus major capsid protein alter virion stability and aphid transmission.
The coat protein (CP) of potato leafroll virus (PLRV) is the primary component of the capsid, and is a multifunctional protein known to be involved in vector transmission and virus movement within plant hosts, in addition to particle assembly. Thirteen mutations were generated in various regions of the CP and tested for their ability to affect virus-host and virus-vector interactions. Nine of t...
متن کاملFirst Complete Genome Sequence of Potato leafroll virus from Argentina
In this study, we determined for the first time the complete genomic sequence of an Argentinian isolate of Potato leafroll virus (PLRV), the type species of the genus Polerovirus The isolate sequenced came from a Solanum tuberosum plant that had been naturally infected with the virus. Isolate PLRV-AR had a nucleotide sequence identity between 94.4 and 97.3% with several known PLRV isolates worl...
