Researchers showed that stomatal orientation in developing leaves is guided primarily by cell geometry but can be redirected by mechanical stress generated during growth. Using live imaging and modeling, they found tensile forces across the leaf influence how guard cells divide, revealing a dual control system that links tissue mechanics to pore patterning. https://www.cell.com/cell-reports/fulltext/S2211-1247(26)00444-4
