Identification of a protein regulating water transport in Grapevine

28.02.2014

Aquaporins are proteins that form pores in the membrane of biological cells. During the first months of the project, researches conducted in the WP1 have allowed to identify VvSIP1 as a aquaporin regulating water transport in Vitis vinifera. This major intrinsic protein was expressed in leaves and berries from field-grown vines. While its expression accessed by gene transcription was not impacted by water stress and sun exposure in field, in cultured cells, the protein was up-regulated by heat. These findings are essential for the rest of the project as they will allow us to better understand mechanisms governing water transport and regulation in Grapevine.
