A checklist of lianas in Tripura, India was prepared which enumerates about 60 species of lianas in the state. In this present paper, diversity of lianas in Tripura was analyzed by field exploration from October 2010 to February 2013. Out of the total 60 species enumerated, 34 species are provided with their phenology and places of occurrence . Fie...

Article
This study was attempted to focus on the pattern of codon usage bias (CUB) of chloroplast genes in two species of Pisum viz. P. fulvum and P. sativum and to identify the factors which influence CUB. Bioinformatic tools were used to understand codon usage pattern in the protein-coding sequences of Pisum chloroplast genomes. It was found that GC cont...
