Abstract A new cation exchangers (CAXs) gene was cloned and characterized from Capsella bursapastoris by rapid amplification of cDNA ends (RACE). The full-length cDNA sequence of cax from C. bursa-pastoris (designated as Cbcax51) was 1754 bp containing a 1398 bp open reading frame encoding a polypeptide of 466 amino-acid residues with a calculated molecular mass of 50.5 kDa and an isoelectric point of 5.69. The predicted CbCAX51 contained an IMP dehydrogenase/GMP reductase domain, two Na+/Ca2+ exchanger protein domains. Comparative and bioinformatics analyses revealed that CbCAX51 showed extensive homology with CAX from other plant species. The expression analysis by different treatments indicated… More >
