Plant heterotrimeric G proteins: New roles in defence, stomatal control and ABA perception (2010–2012)
- Abstract:
- We will study the role of heterotrimeric G proteins in important plant processes such as defence, control of stomatal opening and ABA signalling. We have recently discovered a unique class of G gamma subunits with structural characteristics never before observed in animals or plants. We have evidence that this new subunit is involved in ABA signalling through the recently discovered ABA receptors and hypothesize that they might provide a physical link with the receptor and/or ion channels. We will also study for the first time the role of G proteins in crop species and explore their biotechnological applications. This project will provide a better understanding of plant defence and stomatal aperture mechanisms and ABA signalling.
