*4.5. Gene Structure Analysis*

To analyze gene structure, the exon, and intron structures of *SlUGlcAE* and *AtUGlcAE* genes were generated using the Gene Structure Display Server 2.0 (available online: http://gsds.cbi.pku.edu. cn) [48] by aligning the CDS sequences with the corresponding genomic DNA sequences from the SGN (available online: http://solgenomics.net/) [37].
