Transposon-induced gene activation as a mechanism generating cluster shape somatic variation in grapevine.

Fernandez Lucie L Torregrosa Laurent L Segura Vincent V Bouquet Alain A Martinez-Zapater José M JM

The Plant journal : for cell and molecular biology 20091126 4

We have characterized the genetic and molecular origin of the reiterated reproductive meristem (RRM) somatic variant phenotype of grapevine cultivar Carignan. Here, we show that the extreme cluster proliferation and delayed anthesis observed in this somatic variant is caused by a single dominant mutation. Transcriptional profiling of Carignan and RRM plants during early stages of inflorescence development demonstrated the overexpression of a few regulatory genes, including VvTFL1A, a close TFL1 ...[more]

Transcription profiling of Vitis vinifera cv. Cabernet-Sauvignon leaves obtained from plants grown in different enviroments and infected with vascular ascomycete fungus Eutypa lata.

Project description:Eutypa dieback is a vascular disease that may severely affect vineyards throughout the world. In the present work, microarrays analysis were made in order (i) to improve our knowledge of grapevine (Vitis vinifera cv. Cabernet-Sauvignon) responses to Eutypa lata, the causal agent of Eutypa dieback and (ii) to identify genes that may prevent symptom development. Qiagen/Operon grapevine microarrays bearing 14,500 probes were used to compare between three experimental conditions (in vitro, greenhouse, vineyard), foliar material of infected symptomatic plants (S+R+), infected asymptomatic plants (S-R+), and healthy plants (S-R-). These plants were characterized by symptoms notation after natural (vineyard) or experimental (in vitro, greenhouse) infection, re-isolation of the fungus located in the lignified parts, and the formal identification of E. lata mycelium by PCR. Semi-quantitative RT-PCR experiments were run to confirm the expression of some genes of interest in response to E. lata. Their expression profiles were also studied in response to other grapevine pathogens (E. necator, P. viticola, B. cinerea). (i) Five functional categories including metabolism, defense reactions, interaction with environment, transport and transcription were up-regulated in S+R+ plants compared to S-R- plants. These genes, which cannot prevent infection and symptom development, are not specific since they were also upregulated after infection by powdery mildew, downy mildew and black rot. (ii) Most of the genes that may prevent symptom development are associated with the light phase of photosynthesis. This finding is discussed in the context of previous data on the mode of action of eutypin and Eutypa secreted polypeptide fraction.

RNAs expression profiling in a resistant and a susceptible grapevine cultivar to Plasmopara viticola

Project description:Plasmopara viticola (Berk. and Curt.) Berl. and de Toni is the agent of the destructive disease known as grapevine downy mildew, for the control of which intensive fungicide treatments are required. Natural sources of resistance are available in several wild Vitis species, which are being used in traditional breeding approaches. However, molecular switches, signals and effectors involved in resistance are poorly understood. In this paper we report a microarray analysis of early transcriptional changes associated to P. viticola infection in both susceptible Vitis vinifera and resistant Vitis riparia plants (12 and 24 h post inoculation). To provide a biological basis to the choice of time points for transcriptome analyses, we performed microscopic examinations of infected tissues at 12, 24, 48 and 96 hpi. Data suggest that resistance in V. riparia is mainly a post-infectional event and involves a large reprogramming of host metabolism. Transcripts of signal transduction-related genes are specifically and often strongly accumulated in response to infection. Well known defence genes also show marked transcript increases, especially pathogenesis-related proteins PR-10 and stylbene synthases, and genes related to an hypersensitive reaction. On the other hand, V. vinifera mounts a much weaker transcriptional response, involving mainly defence genes, not effective enough in preventing pathogen infection. Leaves from one resistant (V. riparia cv. Gloire de Montpellier) and one susceptible (V.vinifera cv. Pinot Noir) grapevine cultivars grown in vitro were infected with the oomycete Plasmopara viticola, and transcriptome changes were investigated at 12h and 24h after infection. Three biological replicates were considered and each hybridization was performed twice. One color labeling was performed

Proteome responses of Grapevine to Downy mildew

Project description:A comparative proteomic analysis of grapevine leaves from the resistant genotype V. davidii ‘LiuBa-8’ (LB) and susceptible genotype V. vinifera ‘Pinot Noir’ (PN) at 12 hpi was conducted to understand the complex relationship between grapevine and P. viticola and the molecular mechanisms between difference resistant vitis genotypes at the early stage of infection. A total of 444 and 349 differentially expressed proteins (DEPs) were identified in LB and PN respectively at 12 hpi by iTRAQ. MapMan analysis showed that the majority of these DEPs were related to photosynthesis, metabolism, stress and redox. More up-expressed DEPs involved in photosynthesis and less down-expressed DEPs involved in metabolism contribute to the resistance in LB. PR10.2, PR10.3, HSF70.2 and HSP90.6 are proposed to be key proteins in both compatible and incompatible interactions. Accumulation H2O2 established the ROS signaling in incompatible interaction and APXs, GSTs maybe associated with the resistance of grapevine against downy mildew. Moreover, we verified four proteins to ensure the accuracy of proteome data using PRM. Overall, these data provide new insights into molecular events and provide valuable candidate proteins that could be used to illuminate molecular mechanisms underlying the incompatible and compatible interaction in early stage and eventually to be exploited to develop new protection strategy against downy mildew in grapevine.
