Is botany a good course to take to enable you to genetically engineer plants?

Considering that botany is plant biology obviously, so knowing about how the plant works would help in genetically engineering it. Or am I off by a mile? F.Y.I. If you assume I'd G.E. food, no, I'd actually want to G.E. flowers, in order to...enhance fragrance or color, or to make it blossom longer etc..though I suppose that would take quite some time of study to understand those processes..anyway, so...yea.
