Fructose 1,6-biphosphate aldolase (FBA) is Aldolase superfamily protein. It is a key enzyme in plants, which is involved not only in glycolysis and gluconeogenesis in the cytoplasm, but also in the Calvin cycle in plastids. In the current study, eight FBA family genes (AtFBA1-8) were identified and analyzed in Arabidopsis thaliana: FBA1 (AT2G21330) , FBA2 (AT4G38970) , FBA3 (AT2G01140) , FBA4 (AT5G03690) , FBA5 (AT4G26530) , FBA6 (AT2G36460) , FBA7 (AT4G26520) , FBA8 (AT3G52930) .
