Abstract: Comparing complete animal mitochondrial genome sequences is becoming increasingly common as a model for genome evolution and phylogenetic reconstruction. In the present work, we compare the complete mitochondrial genome sequences of five species of cetaceans and artiodactyls and infer phylogenetic relationships among them. The genome of the taxa contains the 37 genes found in a typical mammalian genome, a general structure that is highly-conserved among species. Phylogenetic trees constructed using MP, ML, and BI methods show a similar topology, and indicate the paraphyly of Artiodactyla, due to the sister-group relationship between the Cetacea and the Hippopotamidae. The study confirms that mitogenomics is a useful tool for research on mammal phylogenetics, but recognizes that increased taxon sampling is still required to resolve existing differences between nuclear and mitochondrial gene trees.

Abstract: The farmers have been facing problems. They are maintaining to mostly food grains and also fiber. And other hand, this increased production will depend on natural resources. Mostly land is converted to fertile land to non-agricultural purposes. The land degradation from erosion, water logging, mining and Stalinization etc. The increasing agricultural production is most difficult in Asia where cropping intensity is already highest in the developing world. The yield increase is limited by poor agricultural practices that result in unsustainable family systems. The adoption of modern farming system is forwarded. The millions of the poor people need access to updated new modern technology. The rural people are being depended on multi-traditional innovative ideas.
