- Phospholipase Dalpha3 is involved in the hyperosmotic response in Arabidopsis (2008), Plant Cell, 20, 803-816.
Application
| Application | Comment | Organism |
|---|---|---|
| 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 |
