Protein Variants

EC Number Protein Variants Comment Organism
3.1.4.4 additional information PLDalpha3-knockout plants are less tolerant to salt stress than wild-type plants. In addition, under water deficit conditions, PLDalpha3-KO plants flower later, whereas PLDalpha3-overexpressing plants flower earlier than wild-type plants. PLDalpha3-KO seeds and seedlings are less sensitive to glucose, whereas overexpression of PLDalpha3 enhances glucose sensitivity compared to the wild-type Arabidopsis thaliana

General Information

EC Number General Information Comment Organism
3.1.4.4 physiological function isozyme PLDalpha3 plays a positive role in hyperosmotic stress through a mechanism different from that for PLDalpha1, which mediates the effect of abscisic acid on stomatal movements. PLDalpha3 enhances root growth and accelerates flowering time under hyperosmotic stress. Alterations of PLDalpha3 activity affect the level of phosphatidic acid, and of transcripts of TOR and AGC2.1, of ABA-responsive genes, and of phosphorylated S6K protein under hyperosmotic stress, overview. PLDalpha3 may be involved in the crosstalk among glucose sensing, abscisic acid response, and S6K activation to regulate growth and development Arabidopsis thaliana
