Abstract

Abstract: The YABBY gene family, as a subfamily of zinc finger super-family, plays a vital role in regulating the development of plant leaf and floral organs. 23 YABBY genes with different subcellular localizations were identified from the genome of upland cotton(Gossypium hirsutum L. acc. TM-1). These 23 YABBY genes distributed on 16 chromosomes and 1 Scaffold, and 9 pairs of them were syntenic genes. The cotton YABBY gene family could be divided into four subfamily groups, and there were homologous genes of Arabidopsis thaliana L. in each group. Furthermore, there were similar motif type and arrangement in each group. The tissue expression analysis showed that the expression pattern of the 23 YABBY genes from TM-1 genome varied among different tissues, and all the YABBY gene family members were expressed in the flower, bud and shoot apical meristem.

Key words: YABBY gene family, upland cotton, genome
