satDNA Analyzer 1.2 as a Valuable Computing Tool for Evolutionary Analysis of Satellite-DNA Families: Revisiting Y-Linked Satellite-DNA Sequences of Rumex (Polygonaceae)

摘要

In a previous paper [1] we showed that Y-linked satellite-DNA sequences of Rumex (Polygonaceae) present reduced rates of evolution in relation to other autosomal satellite-DNA sequences. In the present paper, we re-analyze the same set of sequences by using the satDNA Analyzer 1.2 software, specifically developed by us for analysis of satellite DNA evolution. We do not only confirm our previous findings but also prove that the satDNA Analyzer 1.2 package constitutes a powerful tool for users interested in evolutionary analysis on satellite-DNA sequences. In fact, we are able to gather more accurate calculations regarding location of Strachan positions and evolutionary rates calculations, among others useful statistics. All results are displayed in a very comprehensive multicoloured graphic representation easy to use as an html file. Furthermore, satDNA Analyzer 1.2 is a time saving feature since every utility is automatized and collected in a single software package, so the user does not need to use different programs. Additionally, it significantly reduces the rate of data miscalculations due to human errors, very prone to occur specially in large files.
