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.
