New Phytologist, Volume 248, Issue 4, Page 2092-2110, November 2025.Summary With over 60 parallel origins representing evolutionary replicates, C4 photosynthesis is well‐suited for studying complex trait evolution. However, lineages with diverse C3–C4 intermediate species are scarce, leaving uncertainty in models of C4 evolution.

Unlocking grass leaf development: foundations for tunable cereal design
New Phytologist, Volume 248, Issue 4, Page 1655-1676, November 2025.Summary The grass leaf plays a critical role in global food security, generating the carbon stores in cereal grains, which provide > 50% of global calories. As the global population grows, there is an urgent need to increase food production using fewer resources and to develop more resilient agricultural systems to withstand variable climate conditions

New Phytologist, Volume 248, Issue 3, Page 1205-1224, November 2025.Summary Our understanding of how photosynthetic capacity varies among C4 species and across growth and measurement conditions remains limited. We collated 1696 CO2 response curves of net CO2 assimilation rate (A/Ci curves) from C4 species grown and measured at various environmental conditions and used these data to estimate the apparent maximum ...
