英文摘要Salt stress adversely affects plant growth and development. some plants reduce the damage of high-salt stress by expressing a series of salt-responsive genes. studies of the molecular mechanism of the salt-stress response have focused on the characterization of components involved in signal perception and transduction. in the present work, we cloned and characterized a basic helix-loop-helix (bhlh) encoding gene, orbhlh2, from wild rice (oryza rufipogon), which encodes a homologue protein of ice1 in arabidopsis. orbhlh2 protein localized in the nucleus. overexpression of orbhlh2 in arabidopsis conferred increased tolerance to salt and osmotic stress, and the stress-responsive genes dreblaicbf3, rd29a, cor15a and kin1 were upregulated in transgenic plants. abscisic acid (aba) treatment showed a similar effect on the seed germination or transcriptional expression of stress-responsive genes in both wild type and orbhlh2-overexpressed plants, which implies that orbhlh2 does not depend on aba in responding to salt stress. orbhlh2 may function as a transcription factor and positively regulate satt-stress signals independent of aba in arabidopsis, which provides some useful data for improving salt tolerance in crops.
