Shoot apical meristems (SAM) are resistant to most plant viruses due to RNA silencing, which is restrained by viral suppressors of RNA silencing (VSRs) to facilitate transient viral invasion of the SAM. In many cases chronic symptoms and long-term virus recovery occur, but the underlying mechanisms are poorly understood. Here, we found that wild-type Cucumber mosaic virus (CMVWT) invaded the SA...
Gene silencing using RNAi (RNA interference), has recently been used as a successful laboratory technique in determining the function and control of gene expression and provides a wide range of applications in molecular biology and gene therapy. RNAi is a method of suppressing gene expression. In this direction, a single-stranded RNA molecule of about 21–23 nucleotides, called siRNA (small inte...
Recent studies have identified a conserved WG/GW-containing motif, known as the Argonaute (AGO) hook, which is involved in the recruitment of AGOs to distinct components of the eukaryotic RNA silencing pathways. By using this motif as a model to detect new components in plant RNA silencing pathways, we identified SPT5-like, a plant-specific AGO4-interacting member of the nuclear SPT5 (Suppresso...
The molecular basis for virus-induced disease in plants has been a long-standing mystery. Infection of Arabidopsis by Turnip mosaic virus (TuMV) induces a number of developmental defects in vegetative and reproductive organs. We found that these defects, many of which resemble those in miRNA-deficient dicer-like1 (dcl1) mutants, were due to the TuMV-encoded RNA-silencing suppressor, P1/HC-Pro. ...
گیاهان خانواده کدوئیان دارای اهمیت خوراکی و همچنین داروئی در سراسر جهان می باشند. ویروس زردی شته زاد کدوئیان (cucurbit aphid-born yellow polerovirus: cabyv) یکی از شایع ترین ویروس های آلوده کننده کدوئیان در جهان است. ویروس cabyv کاهش محصول قابل توجهی را در خانواده گیاهی کدوئیان به خصوص خربزه و خیار از طریق کاهش تعداد میوه ایجاد می کند. تنها راه کاهش خسارت این ویروس استفاده از ارقام مقاوم و مبار...
Gene silencing is an important regulatory and defense mechanism in plants. Plant viruses evolved some proteins that suppress cellular RNA interference mechanism. In this work identification of silencing suppressors of potato virus M (PVM) is reported. The cDNA sequences of different PVM open reading frames were cloned into the Gateway-compatible binary T-DNA destination vector pMDC32, harboring...
