Phytocytokine SCREWs increase plant immunity through actively reopening stomata
Journal of Plant Physiology, 2022Plants secreted phytocytokine SMALL PHYTOCYTOKINES REGULATING DEFENSE AND WATER LOSS (SCREWs) and its receptor PLANT SCREW UNRESPONSIVE RECEPTOR (NUT) to counter abscisic acid (ABA)- and pathogen-induced stomatal closure (Liu et al.). This novel signaling process provides plants with a new strategy to increase immunity through disrupting an aqueous ...

Phytocytokine signalling reopens stomata in plant immunity and water loss
Nature, 2022Stomata exert considerable effects on global carbon and water cycles by mediating gas exchange and water vapour1,2. Stomatal closure prevents water loss in response to dehydration and limits pathogen entry3,4. However, prolonged stomatal closure reduces photosynthesis and transpiration and creates aqueous apoplasts that promote colonization by ...

Stomata and sterome in early land plants
Nature, 1986Recognition of pioneering land plants in the fossil record is highly contentious. Because vascular plants possess numerous structural modifications which maintain an internally hydrated environment, attempts to demonstrate the vascular status of megafossils have traditionally dominated research, although more recently evidence from microfossils ...

High-throughput microscopy image analysis of plant stomata
2022High-oil tobacco varieties have been recently engineered to produce increased leaf oil content for future food and fuel needs. An engineered variety of Nicotiana tabacum produces ~30 percent of leaf dry weight in lipids in the form of triacylglycerol (TAG), a significant increase relative to the less than 1 percent storage oil normally found in wild ...

Do plants really need stomata?
Journal of Experimental Botany, 1998There are lower and higher plants, such as lichens, the gametophytes of bryophytes and some species of the isoetid life form which are astomatous. However, these species are small and often restricted to a narrow range of biotic and abiotic environments.
