The transcription factors VaERF16 and VaMYB306 interact to enhance resistance of grapevine to Botrytis cinerea infection.

Botrytis cinerea is a fungus that infects cultivated grape (Vitis vinifera); the identification and characterization of resistance mechanisms in the host is of great importance for the grape industry. Here, we report that a transcription factor in the ethylene-responsive factor (ERF) family (VaERF16) from Chinese wild grape (Vitis amurensis 'Shuang You') is expressed during B. cinerea infection and in response to treatments with the hormones ethylene and methyl jasmonate.

Comparative transcriptomic analysis highlights contrasting levels of resistance of Vitis vinifera and Vitis amurensis to Botrytis cinerea.

Botrytis cinerea is a major grapevine (Vitis spp.) pathogen, but some genotypes differ in their degree of resistance. For example, the Vitis vinifera cultivar Red Globe (RG) is highly susceptible, but V.

Genome-wide identification and expression analysis of the B-box transcription factor gene family in grapevine (Vitis vinifera L.).

Background: B-box (BBX) zinc-finger transcription factors play important roles in plant growth, development, and stress response. Although these proteins have been studied in model plants such as Arabidopsis thaliana or Oryza sativa, little is known about the evolutionary history or expression patterns of BBX proteins in grapevine (Vitis vinifera L.).

Transcriptome Analysis of the Grape- Pathosystem Reveals Novel Effectors and a Robust Defense Response.

is an ascomycetous fungus that causes grape anthracnose, a potentially devastating disease worldwide. In this study, a dual RNA-seq analysis was used to simultaneously monitor the fungal genes related to pathogenesis and grape genes related to defense during the interaction at 2, 3, 4, and 5 days postinoculation. Consistent with their potential roles in pathogenicity, genes for carbohydrate-active enzymes, secondary metabolite synthesis, pathogen-host interaction, and those encoding secreted proteins are upregulated during infection.

Genomic Organization of the B3-Domain Transcription Factor Family in Grapevine ( L.) and Expression during Seed Development in Seedless and Seeded Cultivars.

Members of the plant-specific B3-domain transcription factor family have important and varied functions, especially with respect to vegetative and reproductive growth. Although B3 genes have been studied in many other plants, there is limited information on the genomic organization and expression of B3 genes in grapevine ( L.).

The jasmonate-ZIM domain gene VqJAZ4 from the Chinese wild grape Vitis quinquangularis improves resistance to powdery mildew in Arabidopsis thaliana.

Grape (Vitis vinifera L.) is one of the most widely cultivated and economically important fruits. Most cultivated varieties of grape are highly susceptible to fungal diseases, and one of the most pervasive is powdery mildew, caused by Uncinula necator.

VlbZIP30 of grapevine functions in dehydration tolerance via the abscisic acid core signaling pathway.

Drought stress limits the growth and development of grapevines, thereby reducing productivity, but the mechanisms by which grapevines respond to drought stress remain largely uncharacterized. Here, we characterized a group A bZIP gene from "Kyoho" grapevine, , which was shown to be induced by abscisic acid (ABA) and dehydration stress. Overexpression of in transgenic enhanced dehydration tolerance.

Expression of Vitis amurensis VaERF20 in Arabidopsis thaliana Improves Resistance to Botrytis cinerea and Pseudomonas syringae pv. Tomato DC3000.

Ethylene response factor (ERF) transcription factors play important roles in regulating immune responses in plants. In our study, we characterized a member of the ERF transcription factor family, , from the Chinese wild genotype, Rupr "Shuangyou". Phylogenetic analysis indicated that belongs to group IXc of the ERF family, in which many members are known to contribute to fighting pathogen infection.

Genome-wide identification and expression analyses of the homeobox transcription factor family during ovule development in seedless and seeded grapes.

Seedless grapes are of considerable importance for the raisin and table grape industries. Previous transcriptome analyses of seed development in grape revealed that genes encoding homeobox transcription factors were differentially regulated in seedless compared with seeded grape during seed development. In the present study, we identified a total of 73 homeobox-like genes in the grapevine genome and analyzed the genomic content and expression profiles of these genes.
