Identification and characterization of a second plasma membrane H(+)-ATPase gene subfamily in Nicotiana plumbaginifolia

A cDNA clone was isolated for a fourth pma gene encoding a putative plasma membrane H(+)-ATPase of Nicotiana plumbaginifolia. The sequence of the predicted 952 residue PMA4 polypeptide was compared with those of other known plant PMAs, revealing a higher identity with the Arabidopsis thaliana protei...
