[Objective]To identify and analyze members of MADS-box gene family in loquat,and to ex-plore the expression patterns of MADS-box gene in flower bud development of loquat.[Method]MADS-box genes in loquat were identified by bioinformatics based on the genome database of'Dawuxing'loquat.Conserved motifs,phylogenetic trees and cis-acting elements of the family members were analyzed,and their expression patterns in flower bud development of the'Chunhua 1'and'Guozhenhao3'varieties were analyzed.[Result]A total of 63 MIKCC of EjMADS-box genes were identified in'Chunhua 1'and'Guo-zhenhao3'loquat,which are divided into 13 subfamilies and unevenly distributed on 14 chromosomes.Cis-acting elements related to plant growth and development,stress response,light response and hor-mone response were found in the upstream promoter region of gene family.MADS-box genes correspond-ing to'Chunhua 1'and'Guozhenhao3'loquat showed the same trend,and the trend was mainly divided into continuous increase and continuous decrease,which speculated that MADS-box gene played an im-portant role in the development of flower buds.[Conclusion]The MIKCC of MADS-box gene members and their expression patterns during flower bud development in loquat were preliminarily identified and analyzed.The results provided some reference for the study of MADS-box gene involved in loquat flower bud development.
