Abstract
Peanut seedlings develop from seeds by hypocotyl elongation and differentiation. However, the intricate gene regulatory networks and molecular crosstalk underlying hypocotyl growth in peanuts remain largely unknown. Here, a single-cell gene expression landscape in peanut seedlings was initially developed from diverse tissues, including stems, roots, leaves, and hypocotyls. Core transcription factor interaction networks driving developmental trajectories were identified to decipher hypocotyl cell heterogeneity. Jasmonic acid and cytokinin regulate peanut hypocotyl expansion and differentiation based on the number and size of cortex cells and hormone levels between the hypocotyl at 3 and 7 d after germination. We further demonstrated that AhBHLH143 potentially represses hypocotyl elongation by promoting the JA pathway and inhibiting the cytokinin pathway. The single-nucleus transcriptomic atlas of peanut seedlings reveals new insights into hypocotyl development and provides a valuable resource for future investigations of seedling development.
