Abstract:
Taking kiwifruit as the experimental material，bioinformatics analyses of the kiwifruit FBA gene family members were conducted using software such as TBtools and HMMER to study the response of kiwifruit FBA genes under drought stress,in order to provide reference for the breeding of drought-resistant new varieties of kiwifrunt.The results showed that a total of 9 AcFBA genes were identified，and phylogenetic analysis was performed on these genes.This species was divided into 2 subfamilies，with the 9 genes unevenly distributed across 8 chromosomes.Gene structure analysis revealed that these AcFBA genes had relatively few introns，suggesting that their gene structures were relatively conserved.In addition，the cis-acting elements in the AcFBA genes could be mainly classified into two categories,one associated with hormone responses and the other with environmental stress responses.Under drought stress，a total of 5 AcFBA genes showed significant responses，with 3 being upregulated and 2 downregulated.Among them，the AcFBA4 and AcFBA6 genes might positively regulate the response to drought stress，reducing the damage of drought to kiwi plants.Enrichment analysis indicated that 8 AcFBA genes were enriched in 8 KEGG pathways，and in each KEGG pathway，5 AcFBA genes were regarded as differentially expressed genes (DEGs).This demonstrated that AcFBA genes can participate in photosynthesis and metabolic processes to enhance plant tolerance to drought stress.
