Scholarcy highlights

  • Gibberellins, as one of the important hormones in regulating the growth and development of higher plants, can significantly promote cell elongation and expansion
  • Our results showed that GA3 treatment promoted the growth of celery leaves and caused lignification of celery leaf tissue
  • The transcript levels of genes associated with gibberellins, auxin, cytokinins, ethylene, jasmonic acid, abscisic acid, and brassinolide were altered in response to increased or decreased exogenous gibberellins or inhibitor
  • This study provided a reference for further study of the regulation mechanism of gibberellins metabolism, and exerted effects on understanding the role of gibberellins in the growth and development of celery
