MIKC(C)-type MADS box genes encode transcription factors that play crucial roles in plant growth and development. Analysis of the grapevine (Vitis vinifera) genome revealed up to 38 MIKC(C)-type genes. We report here a complete analysis of this gene family regarding their phylogenetic relationships with homologous genes identified in other sequenced dicot genomes, their genome location, and gen...

Abstract The supply of water to a plant canopy is dependent on the xylem pathway connecting roots leaves. In some plants, sectored pathways can restrict resource distribution, resulting in variable quality organs shoots, yet little known about effects sectoring crop cultivars. this study, we combined sap flow measurements and infusion xylem-specific dyes document functional conductive area from...

Plasmopara viticola, the causal agent of grapevine downy mildew, is one of the most devastating grape pathogen in Europe and North America. Although phytochemicals are used to control pathogen infections, the appearance of resistant strains and the concern for possible adverse effects on environment and human health are increasing the search for alternative strategies. In the present investigat...

• A pixel-based classification of esca-affected grapevine leaves was achieved by HSI. Multiple pre-processing and variable selection methods were tested using PLS-DA. Feature wavelengths identified automatic interval PLS methods. Asymptomatic belonging to vines successfully identified. NIR-HSI could detect foliar symptoms Esca disease complex. Precise reliable identification specific plant dise...

Introduction Identification of vectors and potential vectors of Grapevine yellows (GY) diseases is crucial for epidemiology and control of these important diseases (Boudon-Padieu, 2005). Few information are reported in literature concerning the specificity of vector transmission of phytoplasmas. Some phytoplasma strains seem to be specifically transmitted, for example phytoplasmas in the Elm ye...

The impact of changing climatic conditions on viticulture is currently mainly discussed with respect to alterations in grape physiology, adaptation of cultivars and cultural practice. However, pests and diseases of grapevine are influenced by changing climate, too. They are affected either directly through impacts on their life history and epidemiology or indirectly by changes of grapevine phys...
