Some of the world\u2019s most important crops such as maize and sugar cane use C<sub>4<\/sub> photosynthesis, but so do many of the world\u2019s worst grass invaders such as buffel grass (<em>Cenchrus ciliaris<\/em>) and molasses grass (<em>Melinis minutiflora<\/em>).<\/p>\n<p>A recent paper by Colin Osborne (University of Sheffield) and colleagues, including C\u00b7I\u00b7B post doc Vernon Visser, is the first attempt to catalogue the type of photosynthesis used by every known grass species.
