Title: Mitochondrial markers for identification and phylogenetic studies in insects – A Review Authors: Chhakchhuak, Liansangmawii Abstract: Similar morphology and high genetic diversity poses problems in phylogenetic studies of insects. To solve these problems, mitochondrial based markers have been adopted and are increasingly used as molecular markers for phylogenetic studies. Varied markers have been used for different species of insects, viz., markers for 16S r RNA, 12S r RNA, ND (1-6 genes), ATPase and control regions. Among which protein coding gene, CO-1 is found to be best because of its advantage over others whereas, AT rich region of mitochondrial DNA is the least used marker. A recent advanced technology in phylogenetic analysis; namely mitogenomics have greatly improved this research field. This short review attempted to summarize recent studies on the application of vari ous mitochondrial molecular markers for phylogenetic study of insects

Title: Genetic Divergents and Phylogenetic Relationship of Honeybee Population in Mizoram Authors: Chhakchhuak, Liansangmawii Abstract: Insects belonging to Class Insecta are one of the most interesting and most studied organisms. With a wide range of species diversity, they play important roles in the ecosystem as herbivores, pollinators, parasitoids (Lasalle and Gauld, 1993). The worldwide agricultural production value of insect pollination is estimated to be 153 billion, accounting 9.5 percent of the world agricultural production value used for human food (Gallai et al., 2009). In India, approximately 80 per cent crop plants depend on insect pollination. Among insects, the Hymenopterans, especially the bees, are the most effective pollinators of crops and flowering plants, responsible for pollination in about 70 percent of the world’s cultivated crops (Balachandran et al., 2014). Bees pollinate 16 percent of the total of 0.25 million plant species as well as non agriculture, forest and ornamental plants (Thakur, 2012

Title: Protein 3D structure determination using homology modeling and structure analysis Authors: Chhakchhuak, Liansangmawii Abstract: The protein sequence of aspartate aminotransferase of pig was retrieved from the Swiss-Prot data-base. The appropriate template for homology modeling was determined using Blastp. 3D structures were determined by homology modeling softwares such as Swiss Model and EsyPred3D which passed quality test by ProQ software and set for further analysis. The pockets determined by CASTp server for the predicted structures showed a significant difference in the pocket area and volume, which were due to structural deviation between the residues 30-40 found in the 3d-ss software. Both the structures were analyzed using ProFunc tool which showed different functions as they had different structures and active sites. Thus the structure plays a vital role in determining its function.
