Nighttime Stomatal Conductance and Transpiration in C3 and C4 Plants

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...

Interspecific variation in nighttime transpiration and stomatal conductance in a mixed New England deciduous forest.

Transpiration is generally assumed to be insignificant at night when stomata close in response to the lack of photosynthetically active radiation. However, there is increasing evidence that the stomata of some species remain open at night, which would allow for nighttime transpiration if there were a sufficient environmental driving force. We examined nighttime water use in co-occurring species...

Night-time conductance in C3 and C4 species: do plants lose water at night?

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,...

C3 and C4 Complement Levels in Iron Deficiency Anemia

Background and Objectives: Complement proteins are some of the most important plasma proteins of the innate immune system. Impaired immune function is reported in subjects who are iron deficient, and there are documents that these patients are prone to infection. This study was conducted to show whether serum C3 and C4 complement change in adult nonpregnant female with iron deficient anemia or ...
