The biochemistry of Rubisco in Flaveria [PDF]

open access: yesJournal of Experimental Botany, 2008
C(4) plants have been reported to have Rubiscos with higher maximum carboxylation rates (kcat(CO(2))) and Michaelis-Menten constants (K(m)) for CO(2) (K(c)) than the enzyme from C(3) species, but variation in other kinetic parameters between the two photosynthetic pathways has not been extensively examined.

The Evolution of C4 Photosynthesis in Flaveria (Asteraceae): Insights from the Flaveria linearis Complex

Plant Physiology, 2022
Abstract Flaveria is a leading model for C4 plant evolution due to the presence of a dozen C3-C4 intermediate species, many of which are associated with a phylogenetic complex centered around Flaveria linearis. To investigate C4 evolution in Flaveria, we updated the Flaveria phylogeny and evaluated gas exchange, starch δ13C, and activity

Cold stability of pyruvate, orthophosphate dikinase of Flaveria brownii

Plant Molecular Biology, 1995
The nucleotide sequences of the complementary DNA of pyruvate, Pi dikinase (PPDK) from Flaveria bidentis, a C4 plant which possesses a cold-sensitive form of PPDK, and Flaveria brownii, a 'C4-like' plant which possesses a cold-tolerant form of PPDK, were determined.

Leaf anatomical characteristics in Flaveria trinervia (C4), Flaveria brownii (C4-like) and their F1 hybrid

Photosynthesis Research, 1990
Several leaf anatomical and ultrastructural characteristics usually related with photosynthetic capacity were examined in two Flaveria species with strong differences in anatomy and their F1 hybrid. Flaveria trinervia (Spreng.) Mohr (C4) was the female parent and F. brownii A.M. Powell (C4-like) was the male parent. Quantitative anatomical analysis was

The future of C4 research – maize, Flaveria or Cleome?

Trends in Plant Science, 2005
C4 photosynthesis has evolved multiple times among the angiosperms: the spatial rearrangement of the photosynthetic apparatus, combined with alterations to the leaf structure, allows CO2 to be concentrated around Rubisco. Higher CO2 concentrations at Rubisco decrease the rate of oxygenation and therefore reduce the amount of energy lost through ...
