Exploring molecular evolution of Rubisco in C3 and CAM Orchidaceae and Bromeliaceae

Abstract

The results revealed that the variability in the Rubisco L-subunit sequence in orchids and bromeliads is composed of coevolving sites under potential positive adaptive signal. The sequence variability was related to δ¹³C in orchids and bromeliads, however it could not be linked to the variability found in the kinetic properties of the studied species.
