Project description:Arbuscular mycorrhizal symbiosis improves water and nutrient uptake by plants and provides them other ecosystem services. Grapevine is one of the major crops in the world. V. vinifera scions are generally grafted onto a variety of rootstocks that confer different levels of resistance against different pests, tolerance to environmental stress, and influence the physiology of the scions. Arbuscular mycorrhizal fungi are involved in the root architecture and in the immune response to soil-borne pathogens. However, the fine-tuned regulation and the transcriptomic plasticity of rootstocks in response to mycorrhization are still unknown. We compared the responses of 10 different grapevine rootstocks to arbuscular mycorrhizal symbiosis (AMS) formed with Rhizophagus irregularis DAOM197198 using RNA sequencing-based transcriptome profiling. We have highlighted a few shared regulation mechanisms, but also specific rootstock responses to R. irregularis colonization. A set of 353 genes was regulated by AMS in all ten rootstocks. We also compared the expression level of this set of genes to more than 2,000 transcriptome profiles from various grapevine varieties and tissues to identify a class of transcripts related to mycorrhizal associations in these 10 rootstocks. Then, we compared the response of the 351 genes upregulated by mycorrhiza in grapevine to their Medicago truncatula homologs in response to mycorrhizal colonization based on available transcriptomic studies. More than 97% of these homologs were expressed in at least one transcriptome profile, and 64% in all profiles. At the intra-specific level, we described for the first time shared and specific grapevine rootstock genes in response to R. irregularis symbiosis. At the inter-specific level, we defined a shared subset of mycorrhiza-responsive genes

Project description:Since the roots of grapevine rootstocks have a direct contact with drying soil and has an important role in abiotic stimuli, any plasticity on the architecture of the rootstocks would enable grapevine varieties to a better respond to drought stress. However, genomics evidences behind the physiological responses of rootstocks under prolonged drought stress are poorly documented in the literature. In the current study, eight widely used hybrid grapevine rootstocks in viticulture were firstly grafted with sultana seedless and subjected to drought stress to test their physiological and biochemical responses. The results of experiment indicated that the roots of V.rupestris X V.berlandieri (110 R, 1103P, 140 Ru) rootstocks possessed much higher water content as well as non-structural carbohydrate and nitrogen concentrations compared to V.riparia X V.berlandieri (SO4, 5BB, 420A, 8B) and V.vinifera X V.berlandieri (41B) hybrids under drought. V.rupestris X V.berlandieri hybrids were also performed much higher root elongation performance under drought compared to other rootstock hybrids. Three rootstock varieties (110R, 5BB and 41B) having different pedigrees and root architectural responses to drought were also investigated at transcriptome level to find out gene regulation network behind differential physiological responses to drought. Transcriptome analysis revealed 2795, 1196 and 1612 differentially expressed transcripts for the roots of 110R, 5BB and 41B, respectively. The highest expression increases in 110R compared to other rootstocks were recorded for the transcripts functional in carbohydrate (SWEET14, CWINV) and nitrate/peptide (NRT1/ PTR FAMILY) transportation as well as osmoregulation (dehydrins, osmotins, LEAs and proline-glycine rich proteins) during drought. Higher induction of these genes in the roots of tolerant 110R genotype indicated importance of efficient uptake of carbohydrate and nitrogen source released from canopy under drought and preservation of water with osmotic regulation on the root elongation and drought tolerance of grapevines. Expression increases in several other pathogenesis related proteins, regulation of cell wall modification enzymes and activity of several secondary metabolites have been also associated to altered root architecture and drought tolerance in the grapevine rootstocks for the first time with the current study.

Project description:The transcriptional response in the shoot apex to hetero-grafting Cabernet Sauvignon (CS) with the rootstocks 1103 Paulsen (CS/1103P) and Riparia Gloire de Montpellier (CS/RG) compared to the auto-grafted control (CS/CS) four months after grafting. Gene expression profiling was done using the Nimblegen whole genome array with 4 biological replicates of 5 pooled shoot apices.

Project description:Genotype, climate, soil qualities, and rootstocks are among the main factors that influence grape development as well as fruit and wine composition. In this work, the rootstock/scion interactions were studied using transcriptomic and metabolic approaches on leaves of Gaglioppo variety, grafted onto thirteen different rootstocks growing in the same locations. The experiments were performed in a vineyard in the south of Italy, characterized by the Mediterranean climate with warm and dry summers. Whole leaf transcriptome of ‘Gaglioppo’ grafted on five selected rootstocks showed high variability in gene expression. In particular, significant modulation of transcripts linked to primary (e.g. carbohydrate and transport) and secondary metabolism (e.g. phenylpropanoids pathways and response to stress) was observed. Interestingly, genes involved in the priming defense responses (e.g stilbenes and defense genes) were strongly activated in some graft combinations. These results were further confirmed by the quantification of stilbene contents. According with these observations, the leaves of ‘Gaglioppo’ grafted on 1103 Paulsen showing the lowest levels of stilbene synthase transcripts and stilbene metabolites, reveal the greater sensitivity to downy mildew in in vitro assay. This study carrying out an extensive analysis of rootstock effects to scion leaves open a useful way to unravel this complex interaction

Project description:Several pathogens infect grapevine, including viruses and viroids. Considering that there are no effective plant protection treatments against these pathogens and vineyards are cultivated through decades usage of high quality and pathogen-free propagation material (rootstocks and scions) is essential. Although presence of regulated pests is routinely checked using ELISA or rarely RT-PCR, these diagnostics methods can detect only particular pathogens moreover can fail to detect variant strains. High-throughput sequencing of small RNAs can be an effective, alternative method to avoid these disadvantages. Since for production of grafts, pathogen free cultivars and rootstocks must be used, 17 grapevine rootstock plantations and 2 rootstock variety collections were selected for characterisation of their virom by high throughput sequencing of virus derived small RNAs.
