|a Membrane lipid remodeling helps in the efficient utilization of phosphorus (P) by replacing phospholipids with galactolipids during P deficiency. Previous studies have shown lipid remodeling in rice under P deficiency; however, main lipid classes did not show association with superior P-use-efficiency in rice genotypes. Here, diverse rice genotypes were extensively phenotyped in normal (NP) and low P (LP) conditions. Based on the phenotypic response to P deficiency, genotypes were identified as tolerant and sensitive. Further, bulks were generated differing in their physiological P-use-efficiency (PPUE) during LP condition. Shoot lipidome profiling of genotypes was performed and used to correlate the abundance of various lipid classes and their constituent species with the PPUE of the genotypes. Lipid remodeling was observed as a P-starvation-induced response in all the genotypes. However, neither total galacto- and phospholipids nor the lipid classes correlated with PPUE during P deficiency. However, the difference in PPUE in the two bulks correlated with specific lipid species of galactolipids (DGDG, MGDG). Further, DGDG34:3 had the highest Mol% among the differentially accumulated lipid species between the two bulks. Our study reveals the importance of specific galactolipids species in rice adaptation to P deficient soils and thus opens new targets for future research
