Enhancer identification through comparative genomics

Enhancer identification through comparative genomics.

With the availability of genomic sequence from numerous vertebrates, a paradigm shift has occurred in the identification of distant-acting gene regulatory elements. In contrast to traditional gene-centric studies in which investigators randomly scanned genomic fragments that flank genes of interest in functional assays, the modern approach begins electronically with publicly available comparati...

Planctomycetes Comparative Genomics: Identification

Update on Comparative Genomics of Legumes Bridging Model and Crop Legumes through Comparative Genomics

The Fabaceae, or legumes, constitute the third largest family of flowering plants, comprising more than 650 genera and 18,000 species (Polhill and Raven, 1981). Economically, legumes represent the second most important family of crop plants after Poaceae (grass family), accounting for approximately 27% of the world’s crop production (Graham and Vance, 2003). On a worldwide basis, legumes contri...

Identification of a Novel Epoxyqueuosine Reductase Family by Comparative Genomics

The reduction of epoxyqueuosine (oQ) is the last step in the synthesis of the tRNA modification queuosine (Q). While the epoxyqueuosine reductase (EC 1.17.99.6) enzymatic activity was first described 30 years ago, the encoding gene queG was only identified in Escherichia coli in 2011. Interestingly, queG is absent from a large number of sequenced genomes that harbor Q synthesis or salvage genes...

Comparative genomics of human stem cell factor (SCF)

Stem cell factor (SCF) is a critical protein with key roles in the cell such as hematopoiesis, gametogenesis and melanogenesis. In the present study a comparative analysis on nucleotide sequences of SCF was performed in Humanoids using bioinformatics tools including NCBI-BLAST, MEGA6, and JBrowse. Our analysis of nucleotide sequences to find closely evolved organisms with high similarity by NCB...
