Transcriptional profiling of Vitis vinifera during grapevine-downy mildew interaction using cDNA microarrays

Project description:Study of gene expression during Plasmopara viticola infection in the resistant Vitis vinifera cultivar 'Regent'. The oomycete fungus Plasmopara viticola (Berk. et Curt.) Berl. et de Toni is responsible for grapevine downy mildew disease. Most of the cultivated grapevines are sensitive to this pathogen, thus requiring intensive fungicide treatments. The molecular basis of resistance to this pathogen is poorly understood. We have carried out a cDNA microarray transcriptome analysis to identify grapevine genes associated with resistance traits. Early transcriptional changes associated with downy mildew infection in the resistant Vitis vinifera cultivar ‘Regent’, when compared to the susceptible cultivar ‘Trincadeira’, were analyzed. Transcript levels were measured at three time-points: 0, 6 and 12 hours post inoculation (hpi). Our data indicate that resistance in V. vinifera ‘Regent’ is induced after infection. This study provides the identification of several candidate genes that may be related to ‘Regent’ defense mechanisms, allowing a better understanding of this cultivar's resistance traits.

Transcriptomic analysis during heat stress and after the following recovery in grapevine (Vitis vinifera L.) leaves

Project description:To elucidate the effect of heat stress and the following recovery on grapevines and identify some regulated genes representing the classical heat stress response and thermotolerance mechanisms, transcript abundance of grapevine (Vitis vinifera L.) were quantified using the Affymetrix Grape Genome oligonucleotide microarray (15,700 transcripts), followed by quantitive Real-Time PCR validation for some transcript profiles. The treatment: heat stress(5h) and the following recovery (18.5h), sampling were conducted at two time respectively. ****[PLEXdb(http://www.plexdb.org) has submitted this series at GEO on behalf of the original contributor, Lijun Wang. The equivalent experiment is VV40 at PLEXdb.]

The molecular basis of resistance to this pathogen is poorly understood. We have carried out a cDNA microarray transcriptome analysis to identify grapevine genes associated with resistance traits. Early transcriptional changes associated with downy mildew infection in the resistant Vitis vinifera cultivar M-bM-^@M-^XRegentM-bM-^@M-^Y, when compared to the susceptible cultivar M-bM-^@M-^XTrincadeiraM-bM-^@M-^Y, were analyzed. Transcript levels were measured at three time-points: 0, 6 and 12 hours post inoculation (hpi).

Two cultivars: control (Trinacedira) and test (Regent). Two biological replicates were performed at 0 hpi, and 3 biological replicates at 6 and 12hpi. At 12hpi, three technical replicates also were performed.

Vitis vinifera rhizosphere characterization: a metaproteome approach

Project description:Rhizosphere is a complex system of interactions between plant roots, bacteria, fungi and animals, where the release of plant root exudates stimulates bacterial density and diversity. However, the majority of the bacteria in soil results to be unculturable but active. The aim of the present work was to characterize the microbial community associated to the root of V. vinifera cv. Pinot Noir not only under a taxonomic perspective, but also under a functional point of view, using a metaproteome approach. Our results underlined the difference between the metagenomic and metaproteomic approach and the large potentiality of proteomics in describing the environmental bacterial community and its activity. In fact, by this approach, that allows to investigate the mechanisms occurring in the rhizosphere, we showed that bacteria belonging to Streptomyces, Bacillus and Pseudomonas genera are the most active in protein expression. In the rhizosphere, the identified genera were involved mainly in phosphorus and nitrogen soil metabolism.
