Identification and characterization of fructose 1,6-bisphosphate aldolase genes in Arabidopsis reveal a gene family with diverse responses to abiotic stresses

► The evolution of AtFBA genes was investigated. ► AtFBA genes showed different expression in tissues, sugars and abiotic responses. ► AtFBAs showed different functions in development and salt and drought stresses. ► These provide strong evidence for AtFBAs in multiple signaling pathways. ► Insight into their further analysis in Arabidopsis is also conferred.
