Multi-gene datasets used in phylogenetic analyses, such as those produced by the sequence capture or target enrichment used in the Genomics for Australian Plants: Australian Angiosperm Tree of Life project, often show discordance between individual gene trees and between gene and species trees. This webinar will explore three different forms of discordance: deep coalescence, paralogy, and reticulation. In each case, it will consider underlying biological processes, how discordance presents in the data, and what bioinformatic or phylogenetic approaches and tools are available to address these challenges. It will cover Yang and Smith paralogy resolution and general information on options for phylogenetic analysis.
Presenter: Dr Alexander Schmidt-Lebuhn, Centre for Australian National Biodiversity Research, CSIRO
Date/time: 20 May 2021 - 12:00-13:00 AEST / 11:30 - 12:30 ACST / 10:00-11:00 AWST
The slides from this webinar are available on Zenodo as a PDF download.
This webinar is part of a series of webinars and workshops developed by the Genomics for Australian Plants (GAP) Initiative that focuses on the analysis of target capture sequence data. In addition to two public webinars, the GAP bioinformatics working group is offering training workshops in the use of newly developed and existing scripts in an integrated workflow to participants in the 2021 virtual Australasian Systematic Botany Society Conference.
