Patterns of LTR retrotransposons in the phylogeny of Eleocharis. An unrooted neighbor-joining phylogenetic tree of analyzed Eleocharis species based on concatenated alignments of the ppc gene and ITS sequences is shown. Numbers above branches indicate bootstrap values. Subgenera of Eleocharis sensu González-Elizondo and Peterson : E = Eleocharis subgenus Eleocharis, S = Eleocharis subgenus Scirpirdium, Z = Eleocharis subgenus Zinserlingia, L = Eleocharis subgenus Limnochloa. Subseries of Eleocharis: E = Eleocharis subgenus Eleocharis subseries Eleocharis. Densities (number of copies per pg of genomic DNA) of the reverse transcriptases of LTR retrotransposons estimated by both dot blot and real-time PCR are indicated by circles. Genome size, C
-value and chromosome number (2n) are indicated by squares.
