Transient soil flooding limits cellular oxygen to roots and reduces crop yield. Plant response to oxygen deprivation involves increased expression of the
alcohol dehydrogenase
gene (ADH) and ethanolic fermentation. Disruption of the Arabidopsis gene that encodes Rop (RHO-like
small G protein
of plants) guanosine triphosphatase (GTPase) activating protein 4 (ROPGAP4), a Rop deactivator, elevates ADH expression in response to oxygen deprivation but decreases tolerance to stress. Rop-dependent production of hydrogen peroxide via a diphenylene iodonium chloride-sensitive calcium-dependent reduced nicotinamide adenine dinucleotide phosphate (NADPH) oxidase is necessary for induction of both ADH and RopGAP4 expression. Tolerance to oxygen deprivation requires Rop activation and RopGAP4-dependent negative feedback regulation. This Rop signal transduction rheostat balances the ability to increase ethanolic fermentation with survival.

NADPH oxidase AtrbohD plays very important roles in modulating many cellular processes through production of signal molecules reactive oxygen species in Arabidopsis. However, whether it regulates the response to waterlogging stress is unclear. In this report, we showed that expression of AtrbohD was markedly induced by waterlogging stress, and mutation in AtrbohD led to clear sensitivity of Arabidopsis plants to waterlogging stress. Moreover, waterlogging-promoted increases in

accumulation were significantly attenuated in two mutant lines of AtrbohD. These results indicate that AtrbohD is required for Arabidopsis tolerance to waterlogging stress. Besides, GUS staining experiments revealed that disruption of
small G protein
ROP2 encoding gene evidently suppressed the increase of AtrbohD expression while defect of AtrbohD did not prominently affect the abundance enhancements of ROP2 transcripts under waterlogged conditions. Together, these data suggest that AtrbohD functions downstream of ROP2 to positively regulate the response to waterlogging stress in Arabidopsis.
