At3g55610: P5CS2 (DELTA 1-PYRROLINE-5-CARBOXYLATE SYNTHASE 2)

encodes delta 1-pyrroline-5-carboxylate synthetase B. Gene expression is induced by dehydration, high salt and ABA. Knock-out mutations in P5CS2 are embryo-lethal. P5CS2 appears to be present in different cells and/or different subcellular locations from P5CS1 in a tissue-dependent manner.
