A Lipidomic Analysis Reveals Dynamic Changes of Polar Lipids for Oil Biosynthesis During Cotyledon Development in <i>Perilla frutescens</i>.

ABSTRACT: Perilla (Perilla frutescens) is an important oilseed crop valued for its rich content of nutraceutical compounds and polyunsaturated fatty acids. While triacylglycerol biosynthesis has been studied, the role of polar lipids during seed development remains poorly characterized. Here, we performed a comprehensive lipidomic analysis of polar lipids in developing perilla seeds across three key stages. A total of 147 molecular species from 10 polar lipid classes were identified. Phosphatidylcholine and phosphatidylethanolamine were the predominant phospholipids, and both decreased markedly during development, with phosphatidylcholine showing the most significant reduction. In contrast, lysophosphatidic acid increased substantially by 62.4%. Conversely, the galactolipids monolactodiacylgl
