Correction: Karyotype evolution in Phalaris (Poaceae): The role of reductional dysploidy, polyploidy and chromosome alteration in a wide-spread and diverse genus.

[This corrects the article DOI: 10.1371/journal.pone.0192869.].

There are errors in Fig 3, Fig 4 and Fig 5. The authors have provided corrected versions here.

Fig 3

Taxonomic classification [9], life form, chromosomal properties and genome size [38] of diploid and tetraploid Phalaris species on a ITS phylogram based on Bayesian inference [8].

Parsimony bootstrap values and Bayesian support are noted above and below the branches.

Fig 4

Possible scenario of reductional dysploidy in the genus Phalaris.

A: Chromosome prototypes (proto) of a fictive ancestral x = 7 genome A karyotype numbered according to the ideograms of P. brachystachys and P. canariensis in Fig 2; B: Pericentromeric break in proto-A7, end-to-end fusion with proto-A2 and proto-A6 and loss of centromere; C: Paracentric inversion of fused arms; D: Reductional dysploidy to an extant x = 6 karyotype with strong asymmetric chromosomes. m—metacentric, sm/st—submetacentric/subtelocentric.

Geographical distribution of different genomes A, B, and C in eight species of Phalaris and possible expansions routes and time of diversification within the genus according to Voshell & Hilu [10].
