Biochemistry seminar: Greg Reeves, the New Zealand Institute for Plant and Food Research

Spanning the species barrier to allow hybridization of C3 and C4 cereal crops

The boundaries delineating successful hybridization between plant species are not fully understood. However, novel breeding methodologies are constantly expanding the limits to reproductive barriers between species. This talk will focus on the development of a new technology that may facilitate transfer of complex traits across species, as exemplified by transfer of aspects of C4 photosynthesis into C3 species.

Introgression of C4 photosynthesis into C3 crops could significantly enhance crop yield, by alleviating photorespiratory losses. However, this objective is challenging because the C4 photosynthetic pathway involves complex modifications to the biochemistry, cell biology, and anatomy of leaves. The primary results of this research have allowed asexual hybridization of C3 and C4 monocots, including important crops such as wheat, which may facilitate transfer of C4 photosynthesis into C3 species through breeding. More broadly, it may enable the incorporation of other complex traits between sexually incompatible species for crop improvement.
