Organism | Comment | Expression |
---|---|---|
Arabidopsis thaliana | the expression of isoforms AHA2 and AHA7 in roots is enhanced under low-phosphorus stress conditions | up |
General Information | Comment | Organism |
---|---|---|
malfunction | isoform AHA2-deficient plants exhibit reduced primary root elongation and lower H+ efflux in the root elongation zone. Isoform AHA7-deficient plants exhibit reduced root hair density and lower H+ efflux in the root hair zone | Arabidopsis thaliana |
physiological function | under low-phosphorus conditions, isoform AHA2 acts mainly to modulate primary root elongation by mediating H+ efflux in the root elongation zone, whereas isoform AHA7 plays an important role in root hair formation by mediating H+ efflux in the root hair zone | Arabidopsis thaliana |
