It was previously shown that plasma membrane (PM) H + ‐ATPases of active cluster roots are acclimated to phosphorus (P) deficiency. In the present study, we followed the question whether the qualitative acclimation of PM H + ‐ATPase is based on isoform‐specific expression. Therefore, three different PM H + ‐ATPase isoforms ( LHA1–LHA3 ) were investigated at the transcriptional level. Our data indicate that LHA1 may play a key role in the qualitative acclimation of PM H + ‐ATPase in cluster roots to P deficiency.
