Abstract: | Background Rubisco enzyme catalyzes the first step in net photosynthetic CO2 assimilation and photorespiratory carbon oxidation and is responsible for almost all carbon fixation on Earth. The large
subunit of Rubisco is encoded by the chloroplast rbcL gene, which is widely used for reconstruction of plant phylogenies due to its conservative nature. Plant systematicists have
mainly used rbcL paying little attention to its function, and the question whether it evolves under Darwinian selection has received little
attention. The purpose of our study was to evaluate how common is positive selection in Rubisco among the phototrophs and
where in the Rubisco structure does positive selection occur. |
