*2.1. The Identification of UGlcAE Gene Family in Tomato*

To identify the *UGlcAE* genes in the tomato, we searched for sequences that contained the particular domain in the tomato protein database using the hidden Markov model (HMM) model of PF01370, and we found nine potential genes (Table 1). The open reading frame (ORF) lengths of *UGlcAE* that were identified in this study ranged from 1221 bp to 1359 bp, encoding peptides varied from 406 to 452 amino acids (aa). All nine *UGlcAE* genes had a single exon.
