Summary Seed vigour is an imperative trait for the direct seeding of rice. Isopropylmalate synthase ( IPMS ) catalyses the committed step of leucine (Leu) biosynthesis, but its effect on seed vigour remains unclear. In this study, rice Os IPMS 1 and Os IPMS 2 was cloned, and the roles of Os IPMS 1 in seed vigour were mainly investigated. Os IPMS 1 and Os IPMS 2 catalyse Leu biosynthesis, and Leu feedback inhibits their IPMS activities. Disruption of Os IPMS 1 resulted in low seed vigour under various conditions, which might be tightly associated with the reduction of amino acids in germinating seeds. Eleven amino acids that associated with stress tolerance, GA biosynthesis and tricarboxylic acid ( TCA ) cycle were significantly reduced in osipms1 mutants compared with those in wide type ( WT ) during seed germination. Transcriptome analysis indicated that a total of 1209 differentially expressed genes ( DEG s) were altered in osipms1a mutant compared with WT at the early germination stage, wherein most of the genes were involved in glycolysis/gluconeogenesis, protein processing, pyruvate, carbon, fructose and mannose metabolism. Further analysis confirmed that the regulation of Os IPMS 1 in seed vigour involved in starch hydrolysis, glycolytic activity and energy levels in germinating seeds. The effects of seed priming were tightly associated with the mRNA levels of Os IPMS 1 in priming seeds. The Os IPMS 1 might be used as a biomarker to determine the best stop time‐point of seed priming in rice. This study provides novel insights into the function of Os IPMS 1 on seed vigour and should have practical applications in seed priming of rice.
