Isolation and characterization of a Vitis vinifera transcription factor, VvWRKY1, and its effect on responses to fungal pathogens in transgenic tobac…

2007

International audience; Pathogen attack represents a major problem for viticulture and for agriculture in general. At present, the use of phytochemicals is more and more restrictive, and therefore it is becoming essential to control disease by having a thorough knowledge of resistance mechanisms. The present work focused on the trans-regulatory proteins potentially involved in the control of the plant defence response, the WRKY proteins. A full-length cDNA, designated VvWRKY1, was isolated from a grape berry library (Vitis vinifera L. cv. Cabernet Sauvignon). It encodes a polypeptide of 151 amino acids whose structure is characteristic of group IIc WRKY proteins. VvWRKY1 gene expression in …

Services écosystémiques rendus par la symbiose mycorhizienne à arbuscule au vignoble

2021

National audience; Qu’appelle-t-on symbiose mycorhizienne ?Le sol est un milieu vivant puisque dans quelques grammes de terre fine se trouvent environ 200 milliards de bactéries, 100 km de filaments de champignons et 200 000 insectes, vers et protozoaires (figure 1). Cette vie souterraine va partager son habitat (le sol) avec les ceps de vigne. Ce fameux « vivre ensemble » est alors défini par le terme « symbiose » (du grec syn : ensemble ; et bios : vivre). Cette définition ne fait pas de distinction vis-à-vis des modalités d’interaction qui peuvent s’établir entre les deux organismes impliqués. Ainsi, des interactions neutres, ou encore du véritable parasitisme, pour lequel un partenaire …
