Bridge Plant tropic responses (phototropism, gravitropism, thigmotropism) are driven by lateral auxin gradients that emerge from an activator-inhibitor reaction-diffusion mechanism identical in mathematical structure to Turing's morphogenetic model, with PIN-mediated polar auxin transport playing the role of the fast-diffusing inhibitor

Lateral redistribution of the phytohormone auxin (IAA) during gravitropism follows a Turing-class reaction-diffusion system: auxin acts as a slowly diffusing activator of its own polar transport while...

Bridge Stomatal aperture regulation solves an optimal control problem: maximise carbon assimilation per unit water lost while operating under uncertain atmospheric conditions — a dynamic optimisation identical in structure to the Lagrangian dual formulation in economics, making plant physiology a natural laboratory for testing optimal resource allocation theory.

Stomata regulate CO2 uptake and water vapor efflux through guard cell movements. A leaf faces a fundamental trade-off: open stomata maximise photosynthesis but lose water; closed stomata conserve wate...
