Wild grapevine, Vitis vinifera subsp. sylvestris is considered as a rare species in Europe and Iran and possesses restricted distribution due to threatening factors. Natural populations of wild grapevine in the north of Iran were evaluated in three wild areas of coastal and plains areas of Miankaleh, submontane areas of Amol and the forest patches of Kojour and a cultivated sample of crop grape...

Résumé — Détection par Elisa du virus de la marbrure de la vigne (GFkV = grapevine fleck virus). L’association du Grapevine fleck virus (GFkV) avec les symptômes de la marbrure de la vigne a été établie par Elisa. La détection par Elisa du GFkV dans les plants de vigne n’est pas possible pendant la totalité du cycle végétatif : dans nos conditions, en Alsace, les mois de juin et juillet c...
Bud dormancy in grapevine is an adaptive strategy for the survival of drought, high and low temperatures and freeze dehydration stress that limit the range of cultivar adaptation. Therefore, development of a comprehensive understanding of the biological mechanisms involved in bud dormancy is needed to promote advances in selection and breeding, and to develop improved cultural practices for exi...
European grapevine populations quickly disappeared from most of their range, massively killed by the spread of North American grapevine pests and diseases. Nowadays taxonomic pollution represents a new threat. A large Vitis complex involves escaped cultivars, rootstocks, and wild grapevines. The study aimed to provide insight into the Vitis complex in the Danube region through field and genetic...
We evaluate copper tolerance and accumulation in Vitis vinifera ssp. sylvestris in populations from a copper contaminated site and an uncontaminated site, and in the grapevine rootstock "41B", investigating the effects of copper (0-23 mM) on growth, photosynthetic performance and mineral nutrient content. The highest Cu treatment induced nutrient imbalances and inhibited photosynthetic function...
Here, we report the surprising and, to our knowledge, unique example of horizontal interkingdom transfer of a human opportunistic pathogen (Propionibacterium acnes) to a crop plant (the domesticated grapevine Vitis vinifera L.). Humans, like most organisms, have established a long-lasting cohabitation with a variety of microbes, including pathogens and gut-associated bacteria. Studies which hav...
Eutypa lata is the causal fungal agent of Eutypa dieback, a serious grapevine necrotic disease. The erratic and delayed (1 to 2 months) appearance of characteristic conidia on culture media and the presence of numerous microorganisms in decaying wood make it difficult either to identify or to detect E. lata in grapevine wood samples. We designed six pairs of PCR primers for diagnosis of E. lata...
Th e infl uence of partial defoliation performed at diff erent grapevine growth stages on yield components, vegetative growth and fruit composition of ‘Istrian Malvasia’ (‘Malvazija istarska’) vines was investigated. During two consecutive seasons partial defoliation was performed manually at three grapevine growth stages; before bloom (BB), aft er bloom (AB), and at the beginning of bunch clos...
Coordinated transcriptional and metabolic reprogramming ensures a plant's continued growth and survival under adverse environmental conditions. Transcription factors (TFs) act to modulate gene expression through complex cis-regulatory element (CRE) interactions. Genome-wide analysis of known plant CREs was performed for all currently predicted protein-coding gene promoters in grapevine (Vitis v...
