Physiological functions are usually expressed on a leaf area basis, whereas leaf mineral concentrations are often expressed on a dry matter basis. If specific leaf weight (SLW; g DM m−2 leaf) differs among genotypes then variability in mineral conc

Onion (Allium cepa L.) plants were examined to determine the photosynthetic role of CO2 that accumulates within their leaf cavities. Leaf cavity CO2 concentrations ranged from 2250 μL L(-1) near the leaf base to below atmospheric (350 μL L(-1)) nea

Photosynthesis rate, ribulsoe-1,5-bisphosphate carboxylase/oxygenase (Rubisco) activation state, and ribulose bisphosphate concentration were reduced after exposing tomato (Lycopersicon esculentum Mill.) plants to light at 4[deg]C for 6 h. Analysis o

Hybrids have been made between species of Flaveria exhibiting varying levels of C4 photosynthesis. The degree of C4 photosynthesis expressed in four interspecific hybrids (Flaveria trinervia [C4] × F. linearis [C3-C4], F. brownii [C4-like] × F. lin

The degree of C4 photosynthesis was assessed in four hybrids among C4, C4-like, and C3-C4 species in the genus Flaveria using 14C labeling, CO2 exchange, 13C discrimination, and C4 enzyme activities. The hybrids incorporated from 57 to 88% of the 14C

Lower respiratory costs were hypothesized as providing an additional benefit in C4 plants compared to C3 plants due to less investment in proteins in C4 leaves. Therefore, photosynthesis and dark respiration of mature leaves were compared between a n

An analog of phosphoenolpyruvate, 3,3-dichloro-2-dihydroxyphosphinoylmethyl-2-propenoate (DCDP), was used to inhibit phosphoenolpyruvate carboxylase and, therefore, assess the contribution of the C4 pathway to photosynthesis in detached leaves of sev

Low conductance to CO2 of bundle sheath cells is required in C4 photosynthesis to maintain high [CO2] at the site of ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco). Elevated [CO2] allows high CO2 assimilation rates by this enzyme and preve

Photosynthetic rates and related anatomical characteristics of leaves developed at three levels of irradiance (1200, 300 and 80 umol · m(-2) · s(-1)) were determined in the C4-like species Flaveria brownii A.M. Powell, the C3-C4-intermediate specie

A mutant plant of Flaveria linearis Lag. expresses reversed O(2) response of photosynthesis (i.e. its apparent photosynthesis is stimulated at atmospheric O(2) levels). The objectives of this study were to determine the genetic inheritance of this tr
