摘要
Objectives:The basic helix-loop-helix(bHLH)transcription factors(TFs)regulate fruit growth in many plants.However,there is no available study on the bHLH gene family in the haplotype-resolved genome of cultivated strawberry(Fragaria×ananassa).Materials and Methods:The 131 FabHLH genes identifed in the strawberry cultivar‘Yanli’haplotype-resolved genome were classifed into 24 subfamilies according to their phylogenetic relationships.Gene structure,conserved motifs,and chromosomal locations were investigated using bioinformatics.Results:In total,15 FabHLH genes potentially involved in fruit development were screened based on transcriptome analysis of different stages of fruit development.We also identifed the cis-regulatory elements of these 15 FabHLH genes,predicted upstream transcription factors,and identifed protein-protein interactions.Conclusions:The fndings of this study improve our understanding of the regulation mediated by bHLH TFs during strawberry fruit growth and maturation.
