Western blot analysis with the antiserum ATP95 revealed a significant increase of protein amounts of the V-H〓-ATPase subunits B and c of S. slasa under 100 and 400 mmol/L NaCl treatment, which gave another evidence for a salt-induced coordinate up-regulation of V-H〓-ATPase subunits at transcription and translation levels. The coordinated salt-induced increase of subunit B, H and c of V-H〓-ATPase from S. salsa at transcription and translation levels indicated an increase of V-H〓-ATPase holoenzyme amounts, which might be the reason for the increase of V-H〓-ATPase activity of S. salsa under salt stress.
