The Basic Leucine Zipper (bZIP) transcription factors (TFs) family is among of the largest and most diverse gene families found in plant species, members bZIP TFs perform important functions developmental processes stress response. To date, genes Platycodon grandiflorus have not been characterized. In this work, a number 47 PgbZIP were identified from genome P. , divided into 11 subfamilies. distribution these on chromosome replication events analyzed. motif, structure, cis -elements, collinearity relationships simultaneously addition, expression pattern analysis ten candidate involved process different tissue parts . Among them, Four ( PgbZIP5 PgbZIP21 PgbZIP25 PgbZIP28 ) responded to drought salt stress, which may potential biological roles development under stress. hub PgbZIP13 PgbZIP30 PgbZIP32 PgbZIP45 mined correlation network analysis, suggesting that form regulatory with other participate regulating growth This study provides new insights regarding understanding comprehensive characterization for further exploration regulation mechanisms coping abiotic
