Phenotypic landscape inference reveals multiple evolutionary paths to C4 photosynthesis [PDF]
eLife, 2013 C4 photosynthesis has independently evolved from the ancestral C3 pathway in at least 60 plant lineages, but, as with other complex traits, how it evolved is unclear.

Current Biology, 2013 SummaryThe number of humans on earth is increasing, generating concerns about food security and spurring efforts throughout the world to increase the productivity of crops. If a way could be found to increase the yield of crops by, say, 20%, it would have immense impact on global food supplies.

Why is C4 photosynthesis so rare in trees? [PDF]
J Exp Bot, 2020 Since C4 photosynthesis was first discovered >50 years ago, researchers have sought to understand how this complex trait evolved from the ancestral C3 photosynthetic machinery on >60 occasions.

Biochemical and diffusional limitations of C4 photosynthesis [PDF]
, 2020 For increasing yield and productivity of C4 food and biofuel crops there is a need to identify biochemical and diffusional limitations of C4 photosynthesis under different environmental conditions.

Exaptation of ancestral cell-identity networks enables C<sub>4</sub> photosynthesis. [PDF]
NatureC4 photosynthesis is used by the most productive plants on the planet, and compared with the ancestral C3 pathway, it confers a 50% increase in efficiency1. In more than 60 C4 lineages, CO2 fixation is compartmentalized between tissues, and bundle-sheath

BMC Genomics, 2023 Background C4 photosynthesis is a mechanism that plants have evolved to reduce the rate of photorespiration during the carbon fixation process. The C4 pathway allows plants to adapt to high temperatures and light while more efficiently using resources ...

Oxygen Requirement and Inhibition of C4 Photosynthesis . An Analysis of C4 Plants Deficient in the C3 and C4 Cycles [PDF]
, 1998 The basis for O2 sensitivity of C4 photosynthesis was evaluated using a C4-cycle-limited mutant of Amaranthus edulis (a phosphoenolpyruvate carboxylase-deficient mutant), and a C3-cycle-limited transformant of Flaveria bidentis (an antisense ribulose-1,5-

Strategies for improving C4 photosynthesis [PDF]
Current Opinion in Plant Biology, 2016 Recent activities to improve photosynthetic performance in crop plants has focused mainly on C3 photosynthesis where there are clear identified targets such as improving Rubisco kinetics, installation of a CO2 concentrating mechanism and alleviating limitations in chloroplast electron transport.

Modeling the Evolution of C4 Photosynthesis [PDF]
Cell, 2013 The prediction and verification of adaptive trajectories on macroevolutionary timescales have rarely been achieved for complex biological systems. Employing a model linking biological information at multiple scales, Heckmann et al. simulate likely sequences of evolutionary changes from C3 to C4 photosynthesis biochemistry.

C4 photosynthesis in Paulownia? A case of inaccurate citations
Plants, People, Planet, 2023 Societal Impact Statement C4 photosynthesis is an ultra‐efficient mode of photosynthesis found in some of our most productive crop species yet is notably rare in trees.
