Bundle sheath chloroplast volume can house sufficient Rubisco to avoid limiting C4 photosynthesis during chilling (J Exp Bot)

It has long been thought that C4 species generally perform less well than C3 species in cold environments as a consequence of a physical space restriction.  C3 species tend to accumulate more rubisco under chilling stress to avoid limiting photosynthesis, but there is less capacity for this in C4 species…
