INTRODUCTION
Signal-transducing GTPases in plants include small G proteins, heterotrimeric G proteins, and, potentially, several unique types of GTP binding proteins that are not members of either of the aforementioned classes. This review will focus on recent discoveries concerning the roles of heterotrimeric and "unconventional" G proteins in plant cell signaling. Small G proteins are reviewed elsewhere in this issue (Yang, 2002). Plant heterotrimeric G proteins have been the subject of several other recent reviews to which the reader is also referred (Ma, 1994; Assmann, 1996; Hooley, 1998; Bischoff et al., 1999; Fujisawa et al., 2001). Ma's review (1994) does a particularly good job of ...
