high temperature is the most important limiting factor for plant growth in many regions. this problem is very serious because of a heading global warming phenomenon. so study of high temperature effects on different cultivars and species and finding out solution to improve plant tolerance is necessary. in this research, effect of mycorrhizalarboscular fungus on some physiological traits of grap...

The past fifty years important advances have been made in the field of grapevine virus research, including characterization of pathogens and control measurements. Still the occurrence of Grapevine fanleaf virus (GFLV), Arabis mosaic virus (ArMV), Tomato black ring virus (TBRV), Grapevine chrome mosaic virus (GCMV), Alfalfa mosaic virus (AMV), Grapevine Bulgarian latent virus (GBLV), Grapevine f...

The full-length coat protein gene of Grapevine fanleaf virus (GFLV) isolates from Iran was characterized byreverse transcription polymerase chain reaction (RTPCR) and sequencing. The expected 1515 bp coatprotein (CP) gene amplicon was obtained for 16 isolates out of 89 that were identified by double antibodysandwich enzyme-linked immunesorbent assay (DASELISA) in a population ...

In grapevine, serine peptidases from the subtilase family were recently associated to Plasmopara viticola resistance. This family in grapevine, first characterized in 2014, was re-analyzed last year and 82 subtilase genes were identified. However, in November of 2016, the National Center for Biotechnology Information database (NCBI) made a new public release of the grapevine genome annotation b...

the incidence of grapevine virus a (gva) is reported from almost all of the major grapevine growing regions in iran. grapevine is vegetatively propagated by rooting of cuttings or grafting. in such plants, viral diseases are transmitted from stock plants to the progeny. therefore, the control of grapevine viruses can be achieved primarily through production of healthy stock plants. in the p...

BACKGROUND Alignment analysis of the Vv-miRNAs identified from various grapevine cultivars indicates that over 30% orthologous Vv-miRNAs exhibit a 1-3 nucleotide discrepancy only at their ends, suggesting that this sequence discrepancy is not a random event, but might mainly derive from divergence of cultivars. With advantages of miR-RACE technology in determining precise sequences of potential...

Miniature inverted-repeat transposable elements (MITEs) are a particular type of defective class II transposons present in genomes as highly homogeneous populations of small elements. Their high copy number and close association to genes make their potential impact on gene evolution particularly relevant. Here, we present a detailed analysis of the MITE families directly related to grapevine "c...

Grapevine (Vitis vinifera) is susceptible to many pathogens which cause significant losses to viticulture worldwide. Chemical control is available, but agro-ecological concerns have raised interest in alternative methods, especially in triggering plant immunity by elicitor treatments. The β-glucan laminarin (Lam) and its sulfated derivative (PS3) have been previously demonstrated to induce resi...

A graft-transmissible disease displaying red veins, red blotches and total reddening of leaves in red-berried wine grape (Vitis vinifera L.) cultivars was observed in commercial vineyards. Next-generation sequencing technology was used to identify etiological agent(s) associated with this emerging disease, designated as grapevine redleaf disease (GRD). High quality RNA extracted from leaves of ...
