The subtilisin-like proteases (SBTs) are a large family of serine peptidases that unique to plants. Previous studies have shown SBTs associated with developmental processes and environmental responses. However, comprehensive identification systematic analysis the SBT not been conducted in cotton. We used bioinformatics methods analyze structural characteristics, phylogenetic relationships, gene structures, expression modes, evolutionary selection pressures stress responses members upland In this study, we identified 120 112 tetraploid cotton species G. hirsutum barbadense, while 67 69 were diploid arboreum raimondii, respectively; these divided into five distinct subfamilies. GhSBT27A, explore its function through virus-induced silencing transmission electron microscopy. These results suggested GhSBT27A was involved response drought stress. lay foundation for further study on mechanism
