✦ Synopsis
Gene SUC4 produced about four fold more invertase activity than did gene SUC5. However, these genes differ in only three positions located in the 5' non-coding region. The difference in gene expression between SUC4 and SUC5 must be due to the G to A transition (position-497) and/or the C to T transition (position -460) in the upstream activator sequences. The sequence TACAAA present in SUC5 can play the same role than the TATAAA box of SUC4.
