Description
Lin Zhu and co-authors study leaf surface bumps in rice in a 2023 paper. Tiny bumps called papillae dot rice leaves and shape how light enters and water leaves. Their effect on photosynthesis was unclear, so the team bred a mutant line that lacks the bumps entirely.
A gene called SPD25 proved to control bump growth on both leaf faces. Mutant leaves held less silicon and wax, lost water faster, and kept less moisture. Their pores closed down to save water, but that also cut the carbon dioxide supply for photosynthesis. Surplus light energy was shed safely as heat, and the light-harvesting system stayed intact. The authors say the bumps strike the balance between food making and water loss.
