|a Abscisic acid (ABA) is the key hormone that regulating plant responses to abiotic stresses. Several basic helix-loop-helix (bHLH) transcription factors have been reported to regulate ABA signaling in Arabidopsis. Paclobutrazol Resistances (PREs) are non-DNA binding bHLH transcription factors involved in the regulation of plant response to several different plant hormones including gibberellin, brassinosteroid and auxin. Here, we show that PREs are involved in the regulation of ABA and salt responses in Arabidopsis. Quantitative RT-PCR results showed that the expression levels of PRE6 as well as several other PRE genes were reduced in response to ABA treatment, but increased to salt treatment. Seed germination assays indicated that ABA sensitivity is reduced in the pre6 mutants, but increased in transgenic plants overexpressing PRE6. On the other hand, the 35S:PRE6 transgenic plants showed enhanced tolerance to salt, whereas little, if any changes were observed in the pre6 mutants. Similar responses to ABA and salt treatments were observed in the pre2 mutants and the transgenic plants overexpressing PRE2, and a slight increased resistance to ABA in seed germination was observed in the pre2 pre6 double mutants. Taken together, our results suggest that at least some of the PRE genes are ABA responsive genes, and PREs may function redundantly to regulate ABA and salt responses in Arabidopsis
