What is Phylogeny of Eleusine (Poaceae: Chloridoideae) based on nuclear ITS and plastid trnT–trnF sequences about?

Phylogenetic relationships in the genus Eleusine (Poaceae: Chloridoideae) were investigated using nuclear ITS and plastid trnT-trnF sequences. Separate and combined data sets were analyzed using parsimony, distance, and likelihood based methods, including Bayesian. Data congruence was examined using character and topological measures. SigniWcant data heterogeneity was detected, but there was little conXict in the topological substructure measures for triplets and quartets, and resolution and clade support increased in the combined analysis. Data incongruence may be a result of noise and insuYcient information in the slower evolving trnT-trnF. Monophyly of Eleusine is strongly supported in all analyses, but basal relationships in the genus remain uncertain. There is good support for a CAIK clade (E. coracana subsp. coracana and africana, E. indica, and E. kigeziensis), with E. tristachya as its sister group. Two putative ITS homeologues (A and B loci) were identiWed in the allotetraploid E. coracana; the 'B' locus sequence type was not found in the remaining species. Eleusine coracana and its putative 'A' genome donor, the diploid E. indica, are conWrmed close allies, but sequence d
