Conserved spatial patterning of gene expression in independent lineages of C4 plants

New Phytologist, Volume 249, Issue 1, Page 24-38, January 2026.
Summary C4 photosynthesis enhances carbon fixation efficiency by reducing photorespiration through the use of an oxygen‐insensitive carboxylase and spatial separation of photosynthesis between mesophyll and bundle sheath cells. The C4 pathway has evolved independently in > 60 plant lineages, but molecular mechanisms underpinning this convergence remain
