Taxonomic differences between Pinus sylvestris and P. uncinata revealed in the stomata and cuticle characters for use in the study of fossil material [PDF]

open access: yes, 2009
Taxonomic differences in the needle epidermis characteristics of Pinus sylvestris L. and Pinus uncinata Ramond ex DC. from two Iberian populations were sought; such information could help identify these species when pollen analysis and the inspection of ...

Rapid non-destructive method to phenotype stomatal traits

open access: yesPlant Methods, 2023
Background Stomata are tiny pores on the leaf surface that are central to gas exchange. Stomatal number, size and aperture are key determinants of plant transpiration and photosynthesis, and variation in these traits can affect plant growth and ...

Variability in Stomatal Adaptation to Drought among Grapevine Cultivars: Genotype-Dependent Responses

open access: yesAgriculture, 2023
Leaf stomata are the primary determinants of the plant water relations. Physiological adaptations of stomata in response to water stress have been extensively reported for grapevine.

Coronatine Facilitates Pseudomonas syringae Infection of Arabidopsis Leaves at Night. [PDF]

open access: yes, 2016
In many land plants, the stomatal pore opens during the day and closes during the night. Thus, periods of darkness could be effective in decreasing pathogen penetration into leaves through stomata, the primary sites for infection by many pathogens ...

The dynamics of embolism refilling in abscisic acid (ABA)-deficient tomato plants. [PDF]

open access: yes, 2012
Plants are in danger of embolism formation in xylem vessels when the balance between water transport capacity and transpirational demand is compromised.

Stomatal Size in Induced Polyploids in Cucurbita1

open access: yesHortScience, 1974
Abstract Increased stomatal size is a much used incidator to screen seedling populations for suspected polyploidy after treatment with colchicine. We have found this technique valid for distinguishing polyploidy in a number of species and interspecific hybrids of Cucurbita.

A Stomatal Model of Anatomical Tradeoffs Between Gas Exchange and Pathogen Colonization

open access: yesFrontiers in Plant Science, 2020
Stomatal pores control leaf gas exchange and are one route for infection of internal plant tissues by many foliar pathogens, setting up the potential for tradeoffs between photosynthesis and pathogen colonization.

Microtubule Associated Proteins affect stomatal aperture size

open access: yes, 2020
Climate change threatens the productivity of our agricultural plants. Increased heat and drought conditions challenge plants and reduce crop yield. Stomata are epidermal structures on the surface of plant leaves that mediate multiple physiological processes including photosynthesis, thermoregulation and water homeostasis.

A cell size threshold triggers commitment to stomatal fate in Arabidopsis

open access: yesScience Advances, 2022
How flexible developmental programs integrate information from internal and external factors to modulate stem cell behavior is a fundamental question in developmental biology. Cells of the Arabidopsis stomatal lineage modify the balance of stem cell proliferation and differentiation to adjust the size and cell type ...

Effect of Different Ratios of Red and Blue Light on Maximum Stomatal Conductance and Response Rate of Cucumber Seedling Leaves

open access: yesAgronomy, 2023
Light can regulate leaf stomatal development and movement, but the effects of different red-to-blue light mass ratios on leaf stomatal morphology and openness are not fully understood.
