Abstract： β -amylase（BAM）familygene iswidely present in variousplantsand playsasignificantrole inplant growth and responses to abiotic stressTo further explore the information of the BAM familymembers in pepper and analyze theirexpresionpatternsandgenefunctions，bioinformatics methods wereemployedtoconduct genome-wideidentification，gene structure，phylogeneticanalysis，and expressonpattrnanalysisofthe CaBAMgenefamilyin pepper.Theresultsindicatedthatthere were10CaBAMgenes inpepper，allofwhichwerehydrophilicproteinsanddistributedin the nucleus，cytoplasm，mitochondria，chloroplasts，and plasmamembrane.Phylogeneticanalysis dividedthe CaBAMgene familyinto6groups，andtheconservationofcatalyticresidues Glu-186and Glu-380was higherthan thatoftheflexible loop andinerloop.The promoterregions ofCaBAM genes contained multiple cis-acting elements related to stressand development.TranscriptomeandqRT-PCR analysis showed that CaBAMgeneshaddiferential expression in diferent tissues and under abiotic stres，and CaBAM4， CaBAM5，and CaBAM6 might play roles in the growthand developmentof pepper andresponses toabiotic stres.Theresearchresults provideareference forfurther in-depth studieson thefunctionof the CaBAM gene family in pepper.
