additional information	-	transgenic plants show 5 to 6fold increase in SPDS activity and 1.3 to 2fold increase in the free spermidine content in leaves over the wild type. Significant increase in activity upon chilling in wild type and transgenics. Slightly higher chill-induced increase in SPDS activity in transgenics. pH 8.0, 37°C	Cucurbita ficifolia
