It is now established that G-proteins are involved in the transduction of a number of important processes in plants (Cell division, stomata control, defence, light perception, etc). Nevertheless the data accumulated to date is based on the study of one of the two subunits (alpha) of the G-proteins. Almost nothing is known about the role of the second (and independent) subunit: beta-gamma. We will study for the first time the role of the beta-gamma subunit in plants. We will use a comprehensive approach combining biochemical, physiological, phenotypic, genomic and proteomic studies.

现在已经确定G蛋白参与植物中许多重要过程的转导（细胞分裂、气孔控制、防御、光感知等）。然而，迄今为止积累的数据是基于对G蛋白两个亚基之一（α）的研究。关于第二个（也是独立的）亚基：β-γ的作用几乎一无所知。我们将首次研究β-γ亚基在植物中的作用。我们将使用一个综合的方法结合生物化学，生理学，表型，基因组和蛋白质组学研究。
