Root systems anchor plants to the substrate in addition to transporting water and nutrients, playing a fundamental role in plant survival. The gene mediates gravity signal transduction and participates in root and shoot development and auxin flow in many plants. In this study, a regulator, LsLAZY1, was identified from based on previous transcriptome data. The conserved domain and evolutionary relationship were further analyzed comprehensively. The role of in root development was investigated by genetic transformation and associated gravity response and phototropism assay. Subcellular localization showed that LsLAZY1 was localized in the nucleus. overexpression in () increased the length of the primary roots (PRs) and the number of lateral roots (LRs) compared to . Furthermore, : transgenic seedlings affected auxin transport and showed a stronger gravitational and phototropic responses. It also promoted auxin accumulation at the root tips. These results indicated that affects root development and auxin transport.
