A cDNA clone corresponding to the gene (ZHA1) for a putative plasma
membrane H+-ATPase of a seagrass (Zostera marina L.) was isolated and
sequenced. Comparison of the amino acid predicted sequence from the
nucleotide sequence of ZHA1 with those encoded by known genes for plasma
membrane H+-ATPases from other plants indicated that ZHA1 is most similar
to the gene (PMA4) for a plasma membrane H+-ATPase in a tobacco (84.4%).
Northern hybridization indicated that ZHA1 was strongly expressed in mature
leaves, which are exposed to seawater and have the ability of tolerate
salinity; ZHA1 was weakly expressed in immature leaves, which are protected
from seawater by tightly enveloping sheaths and are sensitive to salinity.
In mature leaves, in situ hybridization revealed that ZHA1 was expressed
specifically in epidermal cells, the plasma membranes of which were highly
invaginated and morphologically similar to those of typical transfer cells.
Therefore, the differentiation cell-like structures, accompanied by the
high-level expression of ZHA1, in the epidermal cells of mature leaves in
particular may be important for the excretion of salt by these cells.
