The phytohormone brassinosteroid (BR) promotes early seedling development via auxin signaling pathway in rapeseed.

ABSTRACT: The phytohormone brassinosteroid (BR) regulate various developmental and physiological processes in plants. However, the function of BR during early seedling development stage in rapeseed is largely unknown. To understand the effects of exogenous BR during early seedling development, the ZS11 and BR-INSENSITIVE (bin2) mutants were treated with BR before seed sowing and seed germination stage under 16/8 hours light/dark cycle. The phenotype results indicated that BR promotes only seedling establishment but not seed germination stage in ZS11, while no function in bin2 mutants. Since BRs play a crucial role in regulation of developmental transition between growth in the dark (skotomorphogenesis) and growth in the light (photomorphogenesis), the ZS11 and bin2 mutants were treated with BR under
