Difference of Germination Temperatures between C3-plants and C4-plants

Dramatic Difference in the Responses of PEPC to Temperature in Leaves of C3 and C4 Plants

Distribution of C3 and C4 Photosynthetic Pathways in Plants

Dramatic difference in the responses of phosphoenolpyruvate carboxylase to temperature in leaves of C3 and C4 plants.

Temperature caused phenomenal modulation of phosphoenolpyruvate carboxylase (PEPC, EC 4.1.1.31) in leaf discs of Amaranthus hypochondriacus (NAD-ME type C(4) species), compared to the pattern in Pisum sativum (a C(3) plant). The optimal incubation temperature for PEPC in A. hypochondriacus (C(4)) was 45 degrees C compared to 30 degrees C in P. sativum (C(3)). A. hypochondriacus (C(4)) lost near...

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...

Regulation of Photosynthesis in C3 and C4 Plants: A Molecular Appmach

Most plants use the C3 pathway of photosynthesis, also called the photosynthetic carbon reduction cycle (PCR), shown in Figure 1A. C3 plants have a single chloroplast type that performs all of the reactions that convert light energy into the chemical energy that is used to fix COp and to synthesize the reduced carbon compounds upon which all life depends. Ribulose-i ,5-bisphosphate carboxylasel...
