He found that leaves grew asymmetrically when ... side contained epidermal cells that differed genetically from the mesophyll cells. When big-leaf epidermal cells surrounded small-leaf mesophyll ...

“When we applied mechanical pressure to the exposed site, we found that this was enough to downregulate ATML1 expression in the outermost mesophyll cells,” says Shinobu Takada, senior author.

This appears to be unlikely since we have found apparently identical structures in the mesophyll cells of wheat, Triticum dicoccum var. ‘Khapli’.

Spongy mesophyll close spongy mesophyllThe plant tissue in a leaf which has loosely packed cells and air spaces between them to allow gas exchange. tissue is packed loosely for efficient gas exchange.

We found that in order to improve overall mesophyll conductance by 20%, the amount of CO 2 that would need to cross the plant cell membrane would need to double." While improved photosynthesis was ...

Overexpression of SHR enhance mesophyll cell division, resulting in a substantial reduction in leaf vein density. However, exogenous auxin treatments led to an increase in leaf vein density.
