Increase (%) of sterol composition in tobacco HMGS-OE seedlings and leaves in comparison to vector (pSa13)-transformed control and elevation of OE-S359A over OE-wtBjHMGS1.

Two independent lines for each OE genotype were analysed. For tobacco OE-wtBjHMGS1, transformants “401” and “402” were tested. For tobacco OE-S359A, transformants “603” and “606” were tested. Values = [(meanOEs - meanpSa13)/meanpSa13]*100. The data presented for OE-S359A in comparison to OE-wtBjHMGS1 was calculated from an average of two transformants (average of “603” and “606” for OE-S359A in comparison to average of “401” and “402” for OE-wtBjHMGS1). Bold font indicates % increase value in OE-S359A which was higher than the corresponding OE-wtBjHMGS1.
