| Description |
Estimation of biological relationship among various taxa is usually measured on some evolutionary models. Majority of the existing evolutionary models ignore insertion and deletion (Indel) event which reduces the computational difficulties but at the same time it causes loss of valuable phylogenetic information. In this study, we developed a modified Jukes-Cantor (M J-C) model to include the insertion and deletion (Indel) information in phylogenetic technique. Utility of modified Jukes-Cantor model was tested in existing phylogenetic methods (UPGMA and NJ). 24 Indel rich chloroplast DNA sequences (trnH-psbA) of different citrus species are used as a dataset in phylogenetic tree construction. In comparison to J-C model, the proposed modified Jukes-Cantor model shows significant improvement in branch support (bootstrap) value in phylogenetic trees, considering Indel information. This new modified J-C model may accelerate the phylogenetic study on Indel-rich DNA sequences. The Indels would be important for phylogenetic tree reconstruction, especially when low level of divergence is found in the studied taxa.
