  1. aAverage GUS activity was measured in culm top, middle and bottom sections of 1-year-old sugarcane transgenic for SCBV21:GUS. The number of independent SCBV21:GUS transgenic lines tested was five (The range of copy number of GUS in these lines is 8–14). GUS activity represents six technical repetitions and is reported with the standard error
