Celery is a vital vegetable belonging to the Apiaceae family.The leaves of celery are its main edible part with high nutritional value.Hormone signaling plays diverse and critical roles in controlling plant growth and development.However,the molecular mechanism of hormone regulating growth and development in celery leaves has not been investigated.Here,we aimed to understand the molecular functions of genes related to hormone metabolism in celery leaf growth and development.A total of 77 hormone-related differentially expressed genes (DEGs) were identified from the transcriptome of celery leaves at three development stages.The roles and interactions of DEGs in the growth and development of celery leaves were discussed.The contents of multiple hormones (IAA,ZR,ABA,BR,GA3,and MeJA) in celery leaf development were also detected.The changes of endogenous hormone level during the development of celery leaves could be regulated by the expressions of hormone-related genes.Our results indicated that the plant hormones had a complex regulatory mechanism for the growth of celery leaves.Our current findings will provide potential valuable references for the future research on celery leaf development.
