The gibberellin(GA)-stimulated transcript GASA proteins are important and widely distributed among different plant species.However,it is little known in genome of moso bamboo(Phyllostachys edulis)and their functional information are limit.In this study,a total of 8 GASA genes were first identified and clustered into three groups.Each clade was contained conserved intron/exon structures and motifs,indicating similar functions shared in the members of same subfamily.PheGASA genes underwent a duplication event approximately 50 million years ago(MYA),suggesting the whole gene duplication event was not the main reason for GASA family expansion.A variety of elements were detected in the promoter sequences of PheGASAs.Additionally.RNA-seq data of developmental flowers and shoots implying regulatory roles of PheGASA family in participating in floral meristem differentiation and shoot fast growing.Overall,it provides a new insight into the GASA gene family and pave a foundation for a further study in moso bamboo.
