During photosynthesis, leaves take in atmospheric CO 2 and release O 2 through stomata, microscopic pore structures in the leaf epidermis (singular = stoma). A pair of guard cells surrounds each ...

The guard cells can therefore count to six,' says Rainer Hedrich. 'When we doubled the stimulation frequency, stoma closure was not accelerated. When we halved it, stoma movement was delayed.' ...

In Arabidopsis, as in nearly all plants, stomata form from precursor cells known as guard mother cells, or GMCs. To form a working stoma -- singular for stomata -- a GMC divides once to yield to ...

Plants grow from something unexpected—carbon drawn in through tiny pores called stomata. At Stanford, researchers are ...

Guard cells control the size of the stomata so that the leaf does not lose too much water in hot, windy or dry conditions. The lower part of the leaf is a spongy layer with loose-fitting cells.

The efflux of osmotically active salts causes water to flow out of the guard cells. They shrink and the stoma closes (right). view more . Credit: Heike Mueller & Peter Ache / University of Wuerzburg.

The researchers engineered guard cells with an increased level of arabinan polymer and showed that this led to cells which were more flexible, so that the stomata opened more widely. “Under ...
