Night-time conductance in C3 and C4 species: do plants lose water at night?
نویسندگان
چکیده
Significant night-time stomatal conductance and transpiration were found for 11 out of 17 species with a range of life histories (herbaceous annual, perennial grass, shrub, tree), photosynthetic pathways (C(3), C(4)), and habitats in the western United States. Across species and habitats, higher night-time conductance and transpiration were associated with higher daytime values. The prevalence, mechanisms and ecological implications of substantial night-time water loss deserve further investigation.

Update on Nighttime Stomatal Conductance in Plants Nighttime Stomatal Conductance and Transpiration in C3 and C4 Plants 1[W]
Incomplete stomatal closure during the night is observed in a diverse range of C3 and C4 species (Fig. 1; Supplemental Table S1) and can lead to substantial nighttime transpirational water loss. Although water loss is an inevitable consequence of stomatal opening for photosynthetic carbon gain, nighttime stomatal opening is unexpected because carbon gain is not occurring and the need to cool le...
متن کاملPhysiological advantages of C4 grasses in the field: a comparative experiment demonstrating the importance of drought
Global climate change is expected to shift regional rainfall patterns, influencing species distributions where they depend on water availability. Comparative studies have demonstrated that C4 grasses inhabit drier habitats than C3 relatives, but that both C3 and C4 photosynthesis are susceptible to drought. However, C4 plants may show advantages in hydraulic performance in dry environments. We ...
متن کاملPhotosynthesis of C3, C3–C4, and C4 grasses at glacial CO2
Most physiology comparisons of C3 and C4 plants are made under current or elevated concentrations of atmospheric CO2 which do not reflect the low CO2 environment under which C4 photosynthesis has evolved. Accordingly, photosynthetic nitrogen (PNUE) and water (PWUE) use efficiency, and the activity of the photosynthetic carboxylases [Rubisco and phosphoenolpyruvate carboxylase (PEPC)] and decarb...
متن کاملGermination Shifts of C3 and C4 Species under Simulated Global Warming Scenario
Research efforts around the world have been increasingly devoted to investigating changes in C3 and C4 species' abundance or distribution with global warming, as they provide important insight into carbon fluxes and linked biogeochemical cycles. However, changes in the early life stage (e.g. germination) of C3 and C4 species in response to global warming, particularly with respect to asymmetric...
متن کاملVariable Photosynthetic Metabolism in Leaves and Stems of Cissus quadrangularis L . ' Received
By measuring titratable acidity, gas exchange parameters, mesophyli succulence, and lSC/UC ratios, we have shown that Cissus quadrgudaris L. has C3-like leaves and stems with Crassulacean acid metabolsm (CAM). In addition, the nonsucculent leaves show the diurnal fluctuations in organic acids termed recycling despite the fact that all CO2 uptake and stomatal opening occurs during the day. Young...
