“…Improving the rapidity of the response of g s to reduce the limitation of A and prevent the slow decrease in A and g s through the day could maintain photosynthetic carbon assimilation for longer, influencing plant productivity and biomass. It should also be kept in mind that the water status of the plant will affect temporal responses of g s (Lawson and Blatt, 2014), which will be species specific, as the transduction of the light signal triggering stomatal opening (Inoue and Kinoshita, 2017) could be modified or reduced to maintain leaf turgor (Aasamaa and Söber, 2011). As a consequence, the water status of the plant is an important determinant of G s that could result in a strong limitation on A throughout the diurnal period (Tuzet et al, 2003;Yan et al, 2016).…”

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

Stomatal control of transpiration is critical for maintaining important processes, such as plant water status, leaf temperature, as well as permitting sufficient CO 2 diffusion into the leaf to maintain photosynthetic rates (A). Stomatal conductance often closely correlates with A and is thought to control the balance between water loss and carbon gain. It has been suggested that a mesophyll-driven signal coordinates A and stomatal conductance responses to maintain this relationship; however, the signal has yet to be fully elucidated. Despite this correlation under stable environmental conditions, the responses of both parameters vary spatially and temporally and are dependent on species, environment, and plant water status. Most current models neglect these aspects of gas exchange, although it is clear that they play a vital role in the balance of carbon fixation and water loss. Future efforts should consider the dynamic nature of whole-plant gas exchange and how it represents much more than the sum of its individual leaf-level components, and they should take into consideration the long-term effect on gas exchange over time.As the waxy surface of most leaves makes them virtually impermeable to CO 2 and water, nearly all CO 2 absorbed by the plant and water lost pass through the stomatal pores (Cowan and Troughton, 1971;Caird et al., 2007;Jones, 2013). Although these pores represent only a small fraction of the leaf surface, stomatal behavior has major consequences for photosynthetic CO 2 fixation and water loss from leaf to canopy levels, influencing carbon and hydrological cycles at global scales (Hetherington and Woodward, 2003;Keenan et al., 2013). Guard cells that surround the stomatal pore open and close in response to environmental stimuli, controlling the flux of gas between the leaf interior and the bulk atmosphere. Stomatal conductance (g s ) appears to be closely linked with mesophyll demands for CO 2 , and a strong correlation between photosynthetic rate (A) and g s is often observed (Wong et al., 1979;Farquhar and Sharkey, 1982;Mansfield et al., 1990;Buckley and Mott, 2013), and although conserved, it is not always constant (Lawson and Morison, 2004;Bonan et al., 2014). However, the A and properties of each leaf may not be identical and depend on acclimation to the surrounding microclimatic conditions; therefore, each leaf could be considered unique (Niinemets, 2016).In order to maintain an appropriate water status, plants must balance water loss between leaves with different properties depending on the availability of soil water, which raises the question about the regulation of g s at the whole-plant level. Early experiments by Meinzer and Grantz (1990) showed that the balance between water loss and water transport capacity enables the maintenance of a constant leaf water status over a wide range of plant sizes and growing conditions. Therefore, plants regulate the transpiration of each leaf independently in response to variations in microclimate by constantly adjusting stomatal aperture. The sto...

“…This conspicuous inversion of the normal positive relationship between aperture and guard cell turgor pressure in the stomata of Sphagnum, however, is not apparent in more derived mosses or hornworts, suggesting that, like vascular plants, stomatal opening in basal species other than Sphagnum requires an increase in guard cell turgor (Wiggans, 1921;Heath, 1938). In vascular plants, particularly angiosperms, active metabolic processes essential for increasing guard cell turgor and opening the pore are well described, particularly in the light (Schroeder et al, 2001;Shimazaki et al, 2007;Inoue and Kinoshita, 2017). This opening process is driven by the hyperpolarization of the guard cell membrane potential through the activation of the plasma membrane proton pump (H + -ATPase).…”

“…These are listed in Table I and can be separated into two categories depending on the involvement of NRL proteins (NRL dependent and NRL independent). Phototropism (Motchoulski and Liscum, 1999;Sakai et al, 2000), petiole positioning and leaf expansion (Inoue et al, 2008b), and chloroplast accumulation are examples of NRLdependent responses, whereas chloroplast-avoidance movement (Kong and Wada, 2014) and stomatal opening (Inoue and Kinoshita, 2017) are NRL independent. While several of these responses can be described as NRL independent, it is worth remembering that functions for 23 members of the NRL family are still lacking.…”
