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

Frontiers 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.

Leaf Gas-exchange Characteristics of Sixteen Cycad Species [PDF]

Journal of the American Society for Horticultural Science, 1997
Leaf gas exchange characteristics for 16 species of cycad were determined under field conditions in Miami, Fla. Net CO 2 assimilation (A CO2 ) ranged from 4.9 μmol·m -2 ·s -1

Photosynthetic parameters and stomatal conductance in attached and detached balsam fir foliage

Plant-Environment Interactions, 2021
Leaf level gas‐exchange measurements can be made on detached foliage to address the challenge of access to the crown of tall trees. However, detachment may impact leaf gas exchange.

Ecophysiology of Mesosphaerum suaveolens (L.) Kuntze (Lamiaceae) under saline stress and salicylic acid

Ciência Rural, 2022
: Mesosphaerum suaveolens (L.) Kuntze is a species widely used in folk medicine and has a high aromatic and therapeutic potential. However, its cultivation in semi-arid regions can be limited by salts in the irrigation water.

Effect of fruit load of the first coffee harvests on leaf gas exchange

Pesquisa Agropecuária Tropical, 2021
Coffee production between the first and second harvest presents a difference in the fruit load with the plant age that could affect the leaf gas exchange.

Stomatal clustering in Begonia associates with the kinetics of leaf gaseous exchange and influences water use efficiency [PDF]

, 2017
Stomata are microscopic pores formed by specialized cells in the leaf epidermis and permit gaseous exchange between the interior of the leaf and the atmosphere.

Assimilate transport in phloem sets conditions for leaf gas exchange [PDF]

Plant, Cell & Environment, 2012
ABSTRACTCarbon uptake and transpiration in plant leaves occurs through stomata that open and close. Stomatal action is usually considered a response to environmental driving factors. Here we show that leaf gas exchange is more strongly related to whole tree level transport of assimilates than previously thought, and that transport of assimilates is a ...

Diurnal Variation in Gas Exchange: The Balance between Carbon Fixation and Water Loss [PDF]

, 2017
Stomatal control of transpiration is critical for maintaining important processes, such as plant water status, leaf temperature, as well as permitting sufficient CO2 diffusion into the leaf to maintain photosynthetic rates (A). Stomatal conductance often
