The mesocotyl, a structure located between the basal part of the seminal root and the coleoptile node of seedlings, contributes to pushing the shoot tip through the soil surface, a function that is essential for the uniform emergence of direct-seeded rice. Its elongation is inhibited by light and induced in darkness. This investigation of an indica rice（P25） with vigorous mesocotyl elongation was aimed at identifying the "omics" basis of its lightinduced growth inhibition. A transcriptomic compa...
