Application

EC Number Application Comment Organism
3.1.4.4 molecular biology knockout and overexpression of PLDalpha3 alter plant response to salinity and water deficit. Alterations of PLDalpha3 result in changes in phosphatidic acid level and membrane lipid composition. PLDalpha3-knockout plants display increased sensitivities to salinity and water deficiency and also tend to induce abscisic acid-responsive genes more readily than wild-type plants, whereas PLDalpha3-overexpressed plants have decreased sensitivities. PLDalpha3-knockout plants flower later than wild-type plants in slightly dry conditions, whereas PLDalpha3-overexpressed plants flower earlier Arabidopsis thaliana
