Given the fact that the species complexes of H. rufescens and H. repandum can be split into several separate species by using samples collected merely from southern Europe4,21,23,24, one can hypothesize that the traditional view on the distribution pattern of Hydnum should be largely revised with the add-in of molecular analyses based on an extensive sampling through its distribution range.
Molecular analyses based on fluorescent in situ hybridization revealed that mucilage contained a large number of pathogenic bacteria (Figure 2D).
The common ancestry of Poritidae and Dendrophylliidae implied by our analyses is consistent with previous molecular analyses based on 28S rDNA [30], 16S rDNA [8], [23], and the nuclear rDNA, CO1 and Cyt B [11].
Both maximum likelihood and Bayesian analyses support the distinction of two major clades ("complex" and "robust" corals) within the Scleractinia (Fig. 1 C and D), as was previously implied by molecular analyses based on mitochondrial 16S rDNA [8], [10], [22], [23], 12S rDNA [25], and CO1 + Cyt B data [11], and on (nuclear) 28S rDNA sequences [11], [29], [30], [32].
This relationship was also suggested by earlier molecular analyses based on a few genes [ 11, 12].
Tick species were identified by morphologic criteria and molecular analyses based on mitochondrial 12S rDNA sequences (4 ).
However, subsequent molecular phylogenetic analyses based on mitochondrial or nuclear genes have produced conflicting topologies13,14,15.
The molecular dating analyses based on the three different models in BEAST largely agreed on node ages with less than 1 million years variation.
Detailed morphological observations and molecular phylogenetic analyses based on nuclear ribosomal DNA and chloroplast DNA sequences supported the recognition of the new species Begonia jinyunensis.
Molecular phylogenetic analyses based on nuclear ITS and chloroplast trnL-F and trnH-psbA sequences strongly support the placement the three new species in Primulina.
Molecular phylogenetic analyses based on nuclear ribosomal DNA and chloroplast DNA sequences indicated that this species was allied to Platycentrum species occurring in Southwest and South-central China and Vietnam, including B. hemsleyana, and clearly separable from these species.
