Plant secretory phospholipase A2 (sPLA2) is a family of lipolytic enzymes, producing free fatty acids and lysophospholipids. We have performed a comparative analysis of sPLA2 family across plants, focusing on gene distribution, phylogenetic analysis, tissue-specific expression, and homology modeling. As a surprise, we described a novel subfamily present in all plant lineages and lacking secretory peptide, which we termed PLA2-like.
