It’s not often you see a Barn Owl with its eyes open in daylight. This one was guarding its nest in the hollow tree - some bloke was pointing a camera at it - causing mild alarm.

Su et al. use the #OnGuard quantitative model to engineer #plants that overexpressed the main tonoplast Ca2+-ATPase gene, ACA11, promoting #stomatal opening and enhancing plant #growth.

Diagram of open (left) and closed (right) stomata complexes, illustrating the mechanism by which overexpression of ACA11 facilitates the accumulation of Ca2+ in the vacuole, influencing Ca2+ storage and leading to an enhanced Ca2+ elevation in response to ABA.  A computer screen is shown, indicating the role of the OnGuard quantitative model, which accurately represents the mechanics and coordination of ion transporters in guard cells.
