SUMMARY With increasing numbers of eukaryotic genome sequences, phylogenetic profiles of eukaryotic genes are becoming increasingly informative. Here, we introduce a new web-tool Phylopro (http://compsysbio.org/phylopro/), which uses the 120 available eukaryotic genome sequences to visualize the evolutionary trajectories of user-defined subsets of model organism genes. Applied to pathways or co...

Serious attention to hazardous chemical pesticides began with publication of the book “Silent Spring” by Rachel Carson in 1962. Scientists believe that agriculture had the greatest impact on the environment. The most reliable evidence comes from application of million tons of chemical fertilizers and pesticides with short or long adverse effects on ecosystem. Therefore, it is essential to imple...

Bioinformatics is an emerging field of science emphasizing the application of mathematics, statistics, and informatics to study and analysis of very large molecular biological (mostly, genetic and genomic) systems (data sets). In a comparatively broader setup of large biological systems without necessarily having a predominant genetic undercurrent, and having genesis in biometry to biostatistic...
