| Abstract | Codon usage patterns of duck hepatitis A virus (HAV) were studied in the present study. The major trends of codon usage patterns were analyzed using principal component analysis on the basis of the relative synonymous codon usage values. Correlation analysis was utilized to reveal the associations of the first two major axes of PCA and nucleotide- or amino acid-relevant indices. Our results showed that compositional constraint and/or mutational pressure are major factors influencing codon usage bias patterns of HAV. However, the influence of natural selection is also prevalent, as indicated by strongly significant correlations between the hydrophobicity, aromaticity, aliphaticity and ionization and the first axis of PCA. Also, ionization could characterize the second axis of PCA. At last, maximum likelihood phylogenetic analysis shows that there are no remarkable geographic clustering patterns of HAV strains in the phylogenetic tree. However, through MANOVA test, there are significant differences on the codon usage patterns among HAV strains from different countries. In conclusion, both mutational pressure and natural selection are of equally great importance to codon usage patterns of duck HAV genomes. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
