Agroclimatological Studies on C3 Plants and C4 Plants

Distribution of C3 and C4 Photosynthetic Pathways in 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...

Controls on Photosynthesis and Sugar Production in C3 and C4 Plants: a Modeling Approach

Photosynthesis is a rather complicated process (Figure 1). Along the pathway, there are a series of energy transformations, redox reactions, and entry and exit points, any of which could influence the rate of the overall process. However, physiological measurements yield surprisingly simple relationships among a few environmental factors such as light and CO2 availability and overall rates of p...

Mycorrhizal Symbiotic Efficiency on C3 and C4 Plants under Salinity Stress – A Meta-Analysis

A wide range of C3 and C4 plant species could acclimatize and grow under the impact of salinity stress. Symbiotic relationship between plant roots and arbuscular mycorrhizal fungi (AMF) are widespread and are well known to ameliorate the influence of salinity stress on agro-ecosystem. In the present study, we sought to understand the phenomenon of variability on AMF symbiotic relationship on sa...

Ratios of C3 Plants: Implications for Palaeodiet Studies

The äC value of a C3 plant is influenced by the species’ response to its environment, which is subject to natural changes with space and time. This paper reviews the magnitude of the resulting variations in plant äC values—the differences between species, and the variations at different spatial and temporal scales—with particular emphasis on studies of tree wood. Because of these variations, an...
