Fig 1.
Molecular clock dated phylogenetic tree of Betoideae subfamily (Amaranthaceae).
Bayesian tree obtained from the BEAST analysis based on the concatenated dataset of ITS and cpDNA markers (matK and rbcL), illustrating the estimated divergence ages at selected calibrated nodes. Posterior probabilities (PP) are given above each branch. The geographic origin of each specimen is provided (right side) with a color code for continental areas and several Macaronesian archipelagos and grey bars differentiate the three gene pools previously described (for further details see Frese [10]) and concordant with the present phylogenetic analysis. C1 to C6 as described in Table 2. Mya, million years ago.
