Machine learning can be as good as maximum likelihood when reconstructing phylogenetic trees and determining the best evolutionary model on four taxon alignments
<p><span>Machine learning can be as good as maximum likelihood when reconstructing phylogenetic topologies and determining the best evolutionary model on four taxon alignments.</span></p> <p><span>Phylogenetic tree reconstruction with molecular data is important in many fields of life science research. The gold standard in this discipline is the Maximum Likelihood tree reconstruction method. Here we show that for quartet trees, Machine Learning using neural networks can be as good as the Maximum Likelihood method to infer the best tree topology and the best model of sequence evolution for nucleotide as well as amino acid sequences. For this purpose we simulated data sets for a wide range of branch lengths, evolutionary models and model parameters and compared the topologies and inferred models obtained with Machine learning with those obtained with the Maximum Likelihood and the Neighbour Joining method. Our results show that neural networks are a promising avenue for determining relatedness between taxa, which is likely to accelerate the construction of phylogenetic trees in the future, while maintaining a high accuracy.</span></p>
APPENDIX 9 in The Amidella clade in Europe (Basidiomycota: Amanitaceae): clarification of the contentious Amanita valens (E.-J.Gilbert) Bertault and the importance of taxon-specific PCR primers for identification
APPENDIX 9. — Phylogenetic reconstruction of ITS sequences from Amanita curtipes related specimens collected in worldwide locations (Appendix 10), using A. lepiotoides Barla as outgroup. The known epithets are next to the brackets, sp designating unknown taxa. Using a 75% coverage cutoff, a total of 584 aligned positions were analysed with the Maximum Likelihood method and the General Time Reversible substitution model (Nei & Kumar 2000), with a discrete Gamma distribution to model evolutionary rate differences among sites (5 categories [gamma parameter 0.4648]). Bootstrap support values above 0.66 (200 replicates) are shown next to the relevant nodes.

APPENDIX 8 in The Amidella clade in Europe (Basidiomycota: Amanitaceae): clarification of the contentious Amanita valens (E.-J.Gilbert) Bertault and the importance of taxon-specific PCR primers for identification

APPENDIX 4 in The Amidella clade in Europe (Basidiomycota: Amanitaceae): clarification of the contentious Amanita valens (E.-J.Gilbert) Bertault and the importance of taxon-specific PCR primers for identification
APPENDIX 4. — Descriptive (mean ± SE) plots for basidiospore length (L), width (l) and L/l ratio (Q). Sample identifiers refer to the Ode samples (Spring 2015) and P01 (Spring 2010).
APPENDIX 2 in The Amidella clade in Europe (Basidiomycota: Amanitaceae): clarification of the contentious Amanita valens (E.-J.Gilbert) Bertault and the importance of taxon-specific PCR primers for identification
APPENDIX 2. — Example of a matched comparison of Amanita ponderosa Malençon & R.Heim (ApoIf2-ITS4) and A. pseudovalens comb. nov., stat. nov. (ITS3- ApsIr3) for the same set of samples representing these two species, along with others of A. curtipes E.-J.Gilbert and A. lepiotoides Barla, and an unknown sample (SM-DB 61). The whole contents of each 20 µL PCR reactions were loaded, to help detect faint signals. Negative controls (neg.) with water instead of DNA. Amanita ponderosa is represented by the valens type (G73) and three samples from Spring 2010 (B07, P08, B10). Amanita pseudovalens is represented by the pseudovalens type (G74), the two MPU samples, Ode05 and Ode07. The Amanita curtipes samples (M03, M04 and M05) may produce a weak co-migrating band with the ITS3-ApsIR3 primer pair, and the A. lepiotoides samples (G08 and Eusk) were negative in both cases. Positive control reactions were not attempted because herbaria materials may be contaminated with other fungi.
