UniProtKB accession:  Q9SGH6

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Alpha-dioxygenase that catalyzes the primary oxygenation step of a variety of 14-20 carbon fatty acids, containing up to three unsaturated bonds, into their corresponding 2R-hydroperoxides (PubMed:12060227, PubMed:10455113). Involved in the production of oxylipins that function in cell signaling, wound healing, and protection from infection (PubMed:12060227, PubMed:10455113). Mediates protection against oxidative stress and cell death, probably by generating some lipid-derived molecules (PubMed:12060227). Promotes local and systemic plant defense in a salicylic acid (SA)-dependent manner, including the establishment of systemic acquired resistance (SAR) in response to incompatible interaction (PubMed:22199234). Involved in a negative regulation of abscisic acid (ABA)-mediated signaling pathway (PubMed:22199234).
