[EN] Phosphoregulation is one of the most important postranslational mechanisms in plants. Among plant protein phosphatases (PPs) the largest family is formed by PP type-2C (PP2Cs), that dephosphorylates target proteins usually contributing to their deactivation and playing a role both in hormone signalling and plant development. PP2Cs best characterized clade, cluster A, has been related with abscisic acid (ABA) signalling pathway acting as negative regulators. FsPP2C2, from Fagus sylvatica, belongs to cluster D PP2Cs, a less characterized clade, and was isolated by our research group as responsive to ABA during beechnuts germination. In order to determine its interacting partners, a Y2H screening was carried out with FsPP2C2 as bait and an Arabidopsis cDNA library as prey. These thesis comprehends the characterization of 3 of these interactions during germination and early development.
