Stomatal Density and Bio‐water Saving
Journal of Integrative Plant Biology, 2007Abstract Bio‐water saving is to increase water use efficiency of crops or crop yield per unit of water input. Plant water use efficiency is determined by photosynthesis and transpiration, for both of which stomata are crucial. Stomata are pores on leaf epidermis for both water and carbon dioxide fluxes that are controlled by two major factors: stomatal

As atmospheric CO 2 concentration increases, the density of stomatal pores on the leaf surface decreases to prevent loss of water during transpiration. An analysis of mutants by Gray et al. reveals that a gene in the plant Arabidposis thaliana called high ...

Differences in stomatal density (SD) and stomatal index (SI) are associated with the conditions of the environment in which they are distributed. Mimosa species are important elements in different plant communities, yet knowledge of the ecological implications of its stomatal characteristics is scarce.

THE INFLUENCE OF LIGHT ON STOMATAL DENSITY IN THE TOMATO
New Phytologist, 1975SUMMARYStomatal densities (stomatal number per unit leaf area) were determined on tomato plants grown at ‘high’ (100 W m−2) and ‘low’ (20 W m−2) light in a growth cabinet. The upper epidermis of a fully expanded leaf in low light had fewer than one stoma mm−2, whilst that in high light had thirty stomata mm−2.

Stomatal density and stomatal index as indicators of paleoatmospheric CO2 concentration
Review of Palaeobotany and Palynology, 2001A growing number of studies use the plant species-specific inverse relationship between atmospheric CO(2) concentration and stomatal density (SD) or stomatal index (SI) as a proxy for paleo-CO(2) levels. A total of 285 previously published SD and 145 SI responses to variable CO(2) concentrations from a pool of 176 C(3) plant species are analyzed here ...

Positive and negative peptide signals control stomatal density
Cellular and Molecular Life Sciences, 2011The stoma is a micro valve found on aerial plant organs that promotes gas exchange between the atmosphere and the plant body. Each stoma is formed by a strict cell lineage during the early stages of leaf development. Molecular genetics research using the model plant Arabidopsis has revealed the genes involved in stomatal differentiation.

Effect of Culture Conditions on Stomatal Density and Stomatal Index in Four Cactus Species
Haseltonia, 2015Abstract: We evaluated type of stomata, as well as differences in stomatal frequency in three areas of the plant (apical, middle and basal) under two culture conditions (in vitro and ex vitro), in four cactus species (Opuntia ficus-indica, Hylocereus undatus, Escontria chiotilla and Mammillaria petterssonii).

Stomatal density of transgenic Arabidopsis thaliana plants over-expressing the SDD1 (stomatal density and distribution) gene was reduced to 40% and in the sdd1-1 mutant increased to 300% of the wild type. CO2 assimilation rate and stomatal conductance of over-expressers and the sdd1-1 mutant were unchanged compared with wild types when measured under ...

Australian Journal of Grape and Wine Research, 2011 Background and Aims: Leaf stomatal density, i.e. number of stomata per unit area of leaf, is a primary determinant of the carbon and water relations of plants.
