Gene stacking

Abstract

A small but increasing proportion of genetically modified crops harbour two or more novel traits due to 'stacked' transgenes. A variety of methods can be used to achieve stacking, albeit with limitations. Transgene stacking can potentially widen the scope of current plant genetic manipulation to allow whole new biochemical pathways to be introduced into plants, or to overcome a range of different factors that limit crop yield. Developing and improving methods for multi-gene stacking in plants is an expanding and exciting field of current research. © 2009 Springer Science+Business Media B.V.
