Sterol profiles of tobacco HMGS-OE seedlings and leaves ( µg/mg dry weight).

<p>Two independent lines for each OE genotype were analysed. For OE-wtBjHMGS1, transformants “401” and “402” were tested. For OE-S359A, transformants “603” and “606” were tested. a indicates significant difference between HMGS-OE and the vector (pSa13)-transformed control; b indicates significant difference between OE-wtBjHMGS1 and OE-S359A. Bold font indicates significant higher sterol content than vector (pSa13)-transformed control and/or the OE-wtBjHMGS1 (<i>P</i><0.01 by the Student's <i>t</i>-test). Values are mean ±SD, n = 5.
