Amplified Fragment Length Polymorphism (AFLP) markers are formed by selective amplification of DNA fragments from digested total genomic DNA. The technique is popular because it is a relatively inexpensive way to produce large numbers of reproducible genetic markers. In this paper, we describe a Bayesian approach to modeling AFLP marker evolution by nucleotide substitution and an MCMC approach ...

In the past, bacterial phylogeny relied almost exclusively on 16S rRNA gene sequence analysis. More recently, multilocus sequence analysis has been used to infer organismal phylogenies. In this study, the dnaJ chaperone gene was investigated as a marker for phylogeny studies in alphaproteobacteria. Preliminary analysis of G+C contents and G+C3s contents (the G+C content of the synonymous third ...

Phylogenetic reconstruction in molecular systematics has largely been achieved using mitochondrial gene sequences and less frequently sequences of nuclear ribosomal RNA genes. At present few other nuclear genes have been identified that could be used to test these phylogenies. C-mos, a single-copy nuclear oncogene, has been identified as a candidate nuclear marker. Data are presented on the use...

Markers are any trait of an organism that can be identified with confidence and relative ease, followed in a mapping population or they defined as heritable entities associated the economically important under control polygenes. Molecular markers have diverse applications fruit crop improvement, particularly areas genetic diversity varietal identification studies, disease diagnostics, hybrid de...

With the astonishing rate that genomic and metagenomic sequence data sets are accumulating, there are many reasons to constrain the data analyses. One approach to such constrained analyses is to focus on select subsets of gene families that are particularly well suited for the tasks at hand. Such gene families have generally been referred to as "marker" genes. We are particularly interested in ...
