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 ...

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 ...

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.

Image-based plant stornata phenotyping
2014 13th International Conference on Control Automation Robotics & Vision (ICARCV), 2014We propose in this paper a fully automatic approach for image-based plant stornata phenotyping. Given a microscopic image of a plant leaf surface, our goal is to automatically detect stornata cells and measure their morphological and structural features, such as stornata opening length and width, and size of the guard cells.

Stomata dimorphism in dicotyledonous plants of temperate climate
Feddes Repertorium, 2010AbstractThe leaves of many tropical trees have besides the normal stomata abnormally large stomata long described as “giant stomata.” They reflect an additional early phase of stomata initiation during leaf ontogeny. In epidermal replicas from more than 200 dicotyledonous species of temperate climate we also found well defined giant stomata or solitary

Liverwort bHLH transcription factors and the origin of stomata in plants
Current Biology, 2023Stomata are distributed in nearly all major groups of land plants, with the only exception being liverworts. Instead of having stomata on sporophytes, many complex thalloid liverworts possess air pores in their gametophytes. At present, whether stomata in land plants are derived from a common origin remains under debate.1,2,3 In Arabidopsis thaliana, a
