Abstract

The use of dominant negative mutants in transient expression assays has produced evidence that the 4 Rabl-related GTPases in Arabidopsis can be subdivided into two families that act on membrane traffic by interaction with different molecules. We will use 2 loss-of-function approaches, insertional mutagenesis and chemically-inducible siRNA, to establish the redundancy relationship within the RabD branch. We will analyse diverse fluorescent protein markers of secretion to ask whether the two branches of the RabD group have different loss-of-function phenotypes and whether dominant-negative and loss-of-function phenotypes are similar. We will also use loss of function phenotypes to test conflicting hypotheses based on the analysis of dominant-negative mutants regarding the role of Rab2 homologues in plants.
