Fig 1.
The Maximum Likelihood phylogenetic tree of the genus Gagea based on 498 bp of internal transcribed spacer (ITS) with bootstrap values (in red).
The analysis involved 50 Gagea individuals and 10 individuals from different genera within the Magnoliopsida class as an outgroup. The scale bar refers to substitutions per site phylogenetic distance.
Fig 2.
The Maximum Likelihood phylogenetic tree of the genus Gagea based on 1,199 DArTseq-derived SNPs with bootstrap values (in red).
The analysis involved 39 Gagea individuals, including five individuals of the section Plecostigma as an outgroup. The scale bar refers to substitutions per site phylogenetic distance.
