Abstract:
... Phytomelatonin is an emerging new plant hormone. The identification of phytomelatonin receptor 1 (PMTR1) has been a turning point for understanding phytomelatonin functions, but many uncertainties remain. Here we highlight how PMTR1-mediated phytomelatonin signaling closes stomata, not just to avoid water loss but also to prevent bacterial invasion at night. ...

Abstract:
... Stomata play a central role in plant responses to abiotic and biotic stresses. Existing knowledge regarding the roles of stomata in plant stress is centered on abiotic stresses and plant–pathogen interactions, but how stomata influence plant–herbivore interactions remains largely unclear. Here, we summarize the functions of stomata in plant–insect interactions and highlight recent discoveries of h ...

Abstract:
... Green roofs can improve ecosystem services in cities; however, this depends on appropriate plant selection. For stormwater management, plants should have high water use to maximize retention and also survive dry periods. Plants adapted to wetter habitats develop “fast” traits for growth, whereas plants from drier habitats develop “slow” traits to conserve water use and survive drought. Therefore, ...

Abstract:
... The coordinated control of ion transport across the two major membranes of differentiated plant cells, the plasma and the vacuolar membranes, is fundamental in cell physiology. The stomata responses to the fluctuating environmental conditions are an illustrative example. Indeed, they rely on the coordination of ion fluxes between the different cell compartments. The cytosolic environment, which is ...

Abstract:
... Cotton (Gossypium hirsutum L.) has nectar containing modified stomates called nectaries that can be located on leaves, bracts or calyces. The nectar attracts some beneficial insects such as bees, but also predatory damaging insects such as heliothines and Lygus species. There is a naturally occurring mutation that eliminates the nectar containing nectaries and makes the cotton plants less attracti ...

Abstract:
... Plants continue to lose water from their leaves even after complete stomatal closure. Although this minimum conductance (gₗₑₐf‐ᵣₑₛ) has substantial impacts on strategies of water use and conservation, little is known about the potential drivers underlying the variability of this trait across species. We thus untangled the relative contribution of water leaks from the cuticle and stomata in order t ...
