TranscriptomicsTemperature stress differentially modulates transcription in meiotic anthers of tolerant and sensitive tomato plants
We have used cDNA-AFLP and microarray analyses to profile the response of the tomato meiotic anther transcriptome to moderate heat stress condition in Moneymaker or Falcorosso and HeatSet1 tomato genotype. Combimatrix microarray technology were applied to obtain a general overview of the gene expres...

TranscriptomicsSelective defoliation affects plant growth, fruit transcriptional ripening program and flavonoid metabolism in grapevine.
The purpose of this study was to quantify the effects of basal leaf removal applied in Sangiovese cultivar at two different phonological stages, pre-bloom and veraison, on berry composition. As very few papers were published about the regulation of gene expression induced by vineyard management tech...

MetabolomicsThe plasticity of the grapevine berry transcriptome
Vitis vinifera cultivar Corvina clone 48 berries were harvested from different vineyards, each located in one of the three most important wine production macro-areas of the Verona region: Bardolino, Valpolicella and Soave, on the basis of the site geographical coordinates. For each of the selected v...

TranscriptomicsGenome-wide analysis of the grapevine stilbene synthase multigenic family: genomic organization and expression profiles upon biotic and abiotic stresses
In this study a complete characterization of the STS multigenic family in grapevine has been performed, commencing with the identification, annotation and phylogenetic analysis of all members and integration of this information with a comprehensive set of gene expression analyses including healthy t...

TranscriptomicsA grapevine anthocyanin acyltransferase, transcriptionally regulated by VvMYBA, can produce most acylated anthocyanins present in grape skins
Anthocyanins are flavonoid compounds responsible for red/purple colours in the leaves, fruit and flowers of many plant species. They are produced through a multistep pathway which is controlled by MYB transcription factors. VvMYBA1 and VvMYBA2 activate anthocyanin biosynthesis in grapevine (Vitis vi...

TranscriptomicsExploring the function of the grape regulators VvMYB5a and MYB5b by heterologous expression in anthocyanin petunia mutants
To obtain insights about the roles of VvMYB5a and VvMYB5b, here we perform complementation analyses using petunia regulatory mutants impaired in pigment accumulation in flower epidermis, proven to be a valid tool for gene functional studies. We created three transgenic petunia lines overexpressing V...

TranscriptomicsExpression profiling in grapevine berry during development and withering processes
Grapevine is a commercially important fruit crop that provides berries for direct consumption, juice pressing, drying (raisins), and fermentation to produce wine. The economic value of the crop has encouraged many researchers to study the physiological and molecular basis of berry development, parti...

TranscriptomicsThe grapevine expression atlas reveals a deep transcriptome shift driving the entire plant into a maturation program
The first genome-wide transcriptomic atlas of grapevine (Vitis vinifera) is based on 54 diverse samples expressing ~93% of predicted grapevine genes. Pollen and senescent leaves have unique transcriptomes but microarray analysis grouped all other samples into vegetative/green or mature/woody categor...

TranscriptomicsTranscriptomic analysis of the late stages of grapevine (Vitis vinifera cv. Cabernet Sauvignon) berry ripening indicates significant induction of ethylene signaling and flavor pathways in the skin.
Background: Grapevine berry, a nonclimacteric fruit, goes through three developmental stages, the last one called the ripening stage, when the berry changes color and dramatically increases in sugar. Flavors derived from terpenoid and fatty acid metabolism develop at the very end of this ripening st...

TranscriptomicsThe plasticity of the grapevine berry transcriptome
Background: Phenotypic plasticity refers to the range of phenotypes a single genotype can express as a function of its environment. These phenotypic variations are attributable to the effect of the environment on the expression and function of genes influencing plastic traits. We investigated phenot...
