The role of actin cytoskeleton reorganisation in mediating Arabidopsis stomatal movement has been established for a decade. However, the signalling machinery facilitating actin reorganisation in response to environmental stimuli remains largely unknown. This study demonstrates that the actin-related protein-2/3 (ARP2/3) complex plays a pivotal role in coupling external signal perception to downstream actin dynamics. A mutation in HSR3, which is allelic to the gene encoding the lRPC2 subunit of the ARP2/3 complex, confers stomatal insensitivity to a range of external stimuli such as light/dark transition, abscisic acid and CaCl2. RT-PCR malysis of guard cell-enriched RNA suggests that HSR3 is expressed in guard cells.
