With Over 60 Independent Losses, Stomata Are Expendable in Mosses

Frontiers in Plant Science, 2020
Because stomata in bryophytes are uniquely located on sporangia, the physiological and evolutionary constraints placed on bryophyte stomata are fundamentally different from those on leaves of tracheophytes. Although losses of stomata have been documented

Automatic segmentation and measurement methods of living stomata of plants based on the CV model

Plant Methods, 2019
Background The stomata of plants mainly regulate gas exchange and water dispersion between the interior and external environments of plants and play a major role in the plants’ health.

A Permeable Cuticle, Not Open Stomata, Is the Primary Source of Water Loss From Expanding Leaves

Frontiers in Plant Science, 2020
High rates of water loss in young, expanding leaves have previously been attributed to open stomata that only develop a capacity to close once exposed to low humidity and high abscisic acid (ABA) levels.

Effects of Heavy Metals on Stomata in Plants: A Review

International Journal of Molecular Sciences, 2023
Stomata are one of the important structures for plants to alleviate metal stress and improve plant resistance. Therefore, a study on the effects and mechanisms of heavy metal toxicity to stomata is indispensable in clarifying the adaptation mechanism of ...

Plant Stomata: An Unrealized Possibility in Plant Defense against Invading Pathogens and Stress Tolerance

Plants, 2023
Stomata are crucial structures in plants that play a primary role in the infection process during a pathogen’s attack, as they act as points of access for invading pathogens to enter host tissues. Recent evidence has revealed that stomata are integral to

Stomata on the abaxial and adaxial leaf surfaces contribute differently to leaf gas exchange and photosynthesis in wheat

New Phytologist, 2022
Summary Although stomata are typically found in greater numbers on the abaxial surface, wheat flag leaves have greater densities on the adaxial surface.

Do stomata optimize turgor‐driven growth? A new framework for integrating stomata response with whole‐plant hydraulics and carbon balance

New Phytologist, 2022
Every existing optimal stomatal model uses photosynthetic carbon assimilation as a proxy for plant evolutionary fitness. However, assimilation and growth are often decoupled, making assimilation less ideal for representing fitness when optimizing ...

Stomata at the crossroad of molecular interaction between biotic and abiotic stress responses in plants

Frontiers in Plant Science, 2022
Increasing global food production is threatened by harsh environmental conditions along with biotic stresses, requiring massive new research into integrated stress resistance in plants.

The why and how of sunken stomata: Does the behavior of encrypted stomata and the leaf cuticle matter?

Annals of Botany, 2022
BACKGROUND Stomatal pores in many species are separated from the free atmosphere by different anatomical obstacles produced by leaf epidermal cells, especially by sunken stomatal crypts, stomatal antechambers and/or hairs (trichomes).
