AtCAX4 is a member of the Ca 2+ /H + exchangers (CAX) family was cloned from cDNA library of Arabidopsis thaliana . AtCAX4 was expressed in all Arabidopsis plant organs, with the highest level in root under normal conditions by quantitative real-time PCR analysis. The expression of AtCAX4 gene is response to Na + , Ca 2+ and Ba 2+ in both the leaves and roots of Arabidopsis . In addition, the pYES2- AtCAX4 transformants confers tolerance to Na + , Ca 2+ and Ba 2+ ions in yeast. These results suggest that AtCAX4 play important role in increasing the Na + , Ca 2+ or Ba 2+ tolerance of yeast. |
