| Abstract: | Objective] The aim was to study adaptive evolution in the RubisCO large subunits of Magnoliophyta crops.Method] Taking Magnoliophyta crops such as corn,rice and others as research materials,the analysis on molecular adaptive evolution was carried out by using codon replacement and maximum likelihood methods.Result] The result showed that RubisCO suffered positive selection effect and 6 amino acid sites were identified.Conclusion] The 6 amino acid sites have important guiding significance for studying ca... |
