Journal ArticleDOI
Ectopic Expression of VvMybPA2 Promotes Proanthocyanidin Biosynthesis in Grapevine and Suggests Additional Targets in the Pathway
Nancy Terrier,Laurent Torregrosa,Agnès Ageorges,Sandrine Vialet,Clotilde Verries,Véronique Cheynier,Charles Romieu +6 more
TL;DR: High-throughput transcriptomic analyses of transformed grapevine organs identified a large set of putative targets of the Vv mybPA1 and VvMybPA2 transcription factors, putative new actors of the proanthocyanidin pathway, such as glucosyltransferases and transporters.
Journal ArticleDOI
Grapevine MATE-Type Proteins Act as Vacuolar H+-Dependent Acylated Anthocyanin Transporters
Camila Gomez,Nancy Terrier,Laurent Torregrosa,Sandrine Vialet,Alexandre Fournier-Level,Clotilde Verries,Jean-Marc Souquet,Jean-Paul Mazauric,Markus Klein,Véronique Cheynier,Agnès Ageorges +10 more
TL;DR: In vitrohibitor studies demonstrated that AM1 and AM3 proteins act in vitro as vacuolar H+-dependent acylated anthocyanin transporters, suggesting that the acyl conjugation was essential for the uptake.
Journal ArticleDOI
In vivo grapevine anthocyanin transport involves vesicle-mediated trafficking and the contribution of anthoMATE transporters and GST
Camila Gomez,Geneviève Conejero,Laurent Torregrosa,Véronique Cheynier,Nancy Terrier,Agnès Ageorges +5 more
TL;DR: In Vitis vinifera (grapevine), two kinds of molecular actors are putatively associated with the vacuolar sequestration of anthocyanins: a glutathione-S-transferase (GST) and two MATE-type transporters, named anthoMATEs.
Journal ArticleDOI
Ectopic expression of VlmybA1 in grapevine activates a narrow set of genes involved in anthocyanin synthesis and transport.
Maria-Cruz Cutanda-Perez,Agnès Ageorges,Camila Gomez,Sandrine Vialet,Nancy Terrier,Charles Romieu,Laurent Torregrosa +6 more
TL;DR: Results suggest that MybA1 activates the last steps of anthocyanin synthesis and transport through the regulation of a narrow, specific spectrum of genes regulated as a cluster.
Journal ArticleDOI
Temperature desynchronizes sugar and organic acid metabolism in ripening grapevine fruits and remodels their transcriptome.
Markus Rienth,Markus Rienth,Laurent Torregrosa,Gautier Sarah,Morgane Ardisson,Jean Marc Brillouet,Charles Romieu +6 more
TL;DR: A careful stage selection and a rigorous control of environmental conditions are needed to address the long-term plasticity of berry development with respect to temperature, as revealed in the first abiotic stress study performed on a fleshy fruits model using RNA-seq for transcriptomic analysis.
