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 ...

The European grapevine moth Lobesia botrana relies on a female produced sex pheromone for long-distance mate finding. Grapevine moth males compete heavily during limited time windows for females. The aim of this study was to investigate the perception of host plant volatiles by grapevine moth males and whether such compounds elicit upwind oriented flights. We compared five host plant headspace ...

BACKGROUND The grapevine is a widely cultivated crop and a high number of different varieties have been selected since its domestication in the Neolithic period. Although sexual crossing has been a major driver of grapevine evolution, its vegetative propagation enhanced the impact of somatic mutations and has been important for grapevine diversity. Transposable elements are known to be major co...

Subtilisin-like proteases, also known as subtilases, are a very diverse family of serine peptidases present in many organisms. In grapevine, there are hints of the involvement of subtilases in defense mechanisms, but their role is not yet understood. The first characterization of the subtilase gene family was performed in 2014. However, simultaneously, the grapevine genome was re-annotated and ...

Grapevine decline, a major global viticulture issue, is defined as multi-year decrease in vine productivity and/or increase mortality. Although grapevine trunk diseases are one of the most-studied causes, decline multifactorial and associated with more than 70 factors, including abiotic biotic hazards. With so many factors to consider, phenomenon difficult understand, especially for winegrowers...

Botryosphaeria dieback is one of the most prevalent grapevine trunk diseases (GTDs), and caused by fungi in Botryosphaeriaceae. Fungi invade vascular systems mainly through pruning wounds, cause cankers necrotic lesions, which lead to decline death. Lasiodiplodia theobromae has been reported as a highly virulent pathogen grapevine, was previously Mexican vineyards. The taxonomy recently revised...

Grapevine yellow speckle viroid 1 (GYSVd1), which is a member of the genus Apscaviroid, causes yellow speckle disease in grapevines. Here, we report the complete de novo genome assembly of GYSVd1 from the grapevine transcriptome and identified 10 single nucleotide polymorphisms of GYSVd1 across the grapevine populations.
