Phylogenetic reconstruction and timetree of the Poaceae and close relatives (Joinvillea, Ecdeioclea, and Flagellaria) based on chloroplast DNA sequence from 700 samples. The branches are color-coded by subfamily and collapsed at the subtribal level. Nodes with posterior probabilities below 0.99 are marked with a white node symbol and the posterior probability is shown. Node bars represent the 95% highest posterior density of node age estimates.

Simplified schematic diagram of multichromosomal mt genomes from two species. A, 18 chromosomes of the mt genome from the human body louse (P. humanus) with size ranging from 3–4 kb (Shao et al., 2009). B, 59 chromosomes of the mt genome from the flowering plant S. noctiflora (OSR) with length varying from 66 kb to 192 kb (Sloan et al., 2012). The gray open circles represent the length variation of chromosomes in the two species relative to each species overall genome length, but are not scaled to comparative sizes between species. The small filled black dots represent the presence of annotated functional genes or duplicated coding sequences in these chromosomes. The size of each circle is not scaled to the length of each multichromosomal mt genome.

Xenotoca variata is one of the most widely distributed species across central Mexico, showing high sexual dimorphism and varying coloration patterns according to its distribution. This diagram illustrates how the populations studied display a clear genetic structure that varies according to the markers analyzed. Two well-defined and highly supported clades were observed across the four markers, with an estimated divergence time of approximately 2.42 Mya. The population of Cuitzeo Lake (highlighted in red) is supported as a possible new species.
