Example Sentences

When there is a water shortage, plants act to conserve water by producing the drought stress hormone ABA to close their stomata.

From Science Daily

Coincidentally, the closure of stomata also obstructs the preferred entry points for nutrient-sucking pests like spider mites.

From Science Daily

Initially, it was noticed that stomata close when plants are attacked by nutrient-sucking pests, leading to various hypotheses, including that this closure could be a plant response to losing water due to the pests' feeding or even that the pests act to close stomata to prevent plants from sending distress volatiles to pest predators.

From Science Daily

The findings published in Plant Physiology found the peak closure of stomata is achieved within a time frame of 24 to 30 hours.

From Science Daily

"We were able to show mite infestation induced a rapid stomatal closure response, with the plant hormone ABA rising in the leaf tissues -- highest in stomatal and vascular cells, but also all other leaf cells measured. We showed through multiple different experiments that stomatal closure hinders mites. Plants that were pre-treated with ABA to induce stomatal closure and then infested with mites showed decreased mite damage, while ABA-deficient mutant plants where stomata cannot close well and plants that have a more stomata are more susceptible to mites."
