Fast dehydration reduces bundle sheath conductance in C4 maize and sorghum
New Phytologist, Volume 244, Issue 6, Page 2197-2209, December 2024.Summary In the face of anthropogenic warming, drought poses an escalating threat to food production. C4 plants offer promise in addressing this threat. C4 leaves operate a biochemical CO2 concentrating mechanism that exchanges metabolites between two partially isolated compartments (mesophyll and bundle sheath), which confers high‐productivity ...

H218O vapour labelling reveals evidence of radial Péclet effects, but in not all leaves
New Phytologist, Volume 244, Issue 4, Page 1263-1274, November 2024.Summary Contradictory evidence exists regarding the relevance of Péclet‐like gradients in leaf water isotopes, making it difficult to accurately predict variation in isotope composition. Here, we use H218O vapour labelling to directly test whether leaf water isotopes diffuse back into the xylem to be carried forward to more distal leaf portions ...

Plasmodesmata and intercellular molecular traffic control
New Phytologist, Volume 243, Issue 1, Page 32-47, July 2024.Summary Plasmodesmata are plasma membrane‐lined connections that join plant cells to their neighbours, establishing an intercellular cytoplasmic continuum through which molecules can travel between cells, tissues, and organs. As plasmodesmata connect almost all cells in plants, their molecular traffic carries information and resources across a range of
