The analysis was performed on the Phylogeny.fr platform and comprised the following steps. |

|
Alignment
MUSCLE 
Outputs: Settings: Run mode: full processing mode |
Sequences were aligned with MUSCLE (v3.8.31) configured for highest accuracy (MUSCLE with default settings). |
|
|
|
Curation
Gblocks
Outputs: Settings: Min. seq. for flank pos.: 85% Max. contig. nonconserved pos.: 8 Min. block length: 10 Gaps in final blocks: no |
After alignment, ambiguous regions (i.e. containing gaps and/or poorly aligned) were removed with Gblocks (v0.91b) using the following parameters: -minimum length of a block after gap cleaning: 10 -no gap positions were allowed in the final alignment -all segments with contiguous nonconserved positions bigger than 8 were rejected -minimum number of sequences for a flank position: 85% |

Phylogeny
PhyML + aLRT
Outputs: Settings: Model: WAG Statistical test: alrt Number of categories: 4 Gamma: estimated Invariable sites: estimated Remove gaps: enabled |
The phylogenetic tree was reconstructed using the maximum likelihood method implemented in the PhyML program (v3.1/3.0 aLRT). The WAG substitution model was selected assuming an estimated proportion of invariant sites (of 0.000) and 4 gamma-distributed rate categories to account for rate heterogeneity across sites. The gamma shape parameter was estimated directly from the data (gamma=0.845). Reliability for internal branch was assessed using the aLRT test (SH-Like). |

TreeDyn
Outputs: Settings: Conformation: rectangular Legend: displayed Branch annotation: bootstrap Font: Times 8 normal |
Graphical representation and edition of the phylogenetic tree were performed with TreeDyn (v198.3). |
