Bioinformatics is considered as computational branch of molecular biology. This has been used by various people of different fields in their own context. Plant taxonomists are also one of them. This has been considering as one more doors towards modern trends in exploring plant taxonomy. In present days molecular data are available for many plant species which can be analyzed in relation to taxonomic or evolutionary or affinity context for different plant species. In this book, bioinformatics data of some leguminous trees have been explored and brought to one platform. Various analytical bioinformatics tools were used to generate the information for particular species or group of species. Authors have tried to generate preliminary bioinformatics data for some leguminous tree species found in Anand district of Gujarat state in INDIA.
