Transgenesis and yield: what are our targets?
Plant metabolic engineering has been used to generate a wide range of transgenic lines in which specific metabolic steps have been targeted. Attempts to increase yield of some agronomically important crops using this approach have highlighted the inherent complexities of modulating plant metabolism. In light of the recent findings by Regierer et al. this article addresses the major challenges faced with respect to enhancing yield through transgenesis.
