Several studies have been done using the matK gene sequence in phylogenetic reconstruction because; the matK has higher variation than any other chloroplast genes. Although the variation is slightly higher at the 5’ region than at the 3’ region, approximate even distribution was observed throughout the entire gene. In addition, the high proportion of transversion of the matK gene might provide more phylogenetic information. These factors underscore the usefulness of the matK gene in systematic studies and suggest that comparative sequencing of matK may be appropriate for phylogenetic reconstruction at subfamily and family levels. Leguminosae family is one of the largest families that contain thousands of species of plants, herbs, shrubs and trees worldwide. In this study, few species which are found in Gujarat state of India have been considered as group of plants with their respective DNA and Protein matK sequences from NCBI database. This study showed that species belonging to Fabaceae (Papilionaceae), Mimosaceae and Caesalpiniaceae subfamilies have different members based on morphological characters or taxonomical classification and on the other side evolutionary results showed that they fall in different groups or species of same genus fall distantly other than in same genus. We concluded that as per botanical classification; species belonging to Leguminosae family are classified differently based on morphological characters while few evolutionary results shows as they are related with morphological or taxonomical classification and other results are not related with morphological or taxonomical classification.
