“…The lack of consensus among classifications suggests that additional characters are required to assess inter-relationships of the genera. Molecular phylogenetic studies using nucleotide sequences of the gene encoding the large subunit of ribulose 1, 5-bisphosphate carboxylase/oxygenase (rbcL) have successfully revealed the phylogenetic relationships of ferns at both generic and familial levels (Hasebe et al 1993(Hasebe et al , 1994(Hasebe et al , 1995Pryer et al 1995;Wolf et al 1994;Sano et al 2000;Little and Barrington 2003). The chloroplast trnL-F sequence region includes the trnL (UAA) intron, trnL (UAA) 3¢ exon and an inter-genic spacer between the trnL (UAA) 3¢ exon and trnF (GAA), which could be more useful at lower taxonomic levels (Taberlet et al 1991).…”

Cyrtomium is an Asiatic genus characterized by anastomosing veins with included veinlets, and comprises about 40 species. We sequenced rbcL and trnL-F sequences of 19 species of Cyrtomium and eight species from related genera in order to elucidate a molecular phylogeny of the genus using maximum-parsimony methods. The phylogenetic trees did not agree with traditional classifications. Cyrtomium was resolved as paraphyletic, and a clade including subseries Balansana of Cyrtomium, Cyrtogonellum, Polystichum subacutidens and Cyrtomidictyum (the BCPC clade) and a second one containing Cyrtomium sensu stricto were monophyletic. The results also implied that: (1) C. uniseriale was synonymous with C. balansae; (2) C. falcatum was likely the female parent of C. devexiscapulae; and (3) based on the rbcL and trnL-F sequence data, C. nephrolepioides and C. grossum were the female parents of C. shingianum and C. chingianum, respectively, although other evidence is needed for the confirmation of this hypothesis.

“…Many studies have employed phylogenetic analysis of DNA sequences of the gene encoding the large subunit of ribulose 1,5-bisphosphate carboxylase/oxygenase (rbcL) to assess phylogenetic relationships of ferns at various taxonomic rank [14][15][16][17][18][19][20][21][22] . A large amount of Polystichum rbcL sequences are now available [14,19,21] , permitting analyses across a diverse array of Polystichum.…”

Inclusion of the Eastern Asia endemic genus Sorolepidium in Polystichum (Dryopteridaceae): Evidence from the chloroplast rbcL gene and morphological characteristics

et al. 2007

The taxonomic status of the Eastern Asia endemic Sorolepidium is controversial. Some authors accept it as member of the large diverse genus Polystichum, whereas others suggest that it is an independent genus separated from the later by the exindusiate sorus and the absence of aristate teeth at the pinnae margins. Here we infer phylogenetic relationship of Sorolepidium using DNA sequences of the chloroplast rbcL gene. Phylogenies were inferred using maximum-parsimony, maximum-likelihood, and Bayesian inference methods. Molecular data establish that Sorolepidium is deeply nested within the large genus Polystichum and has a close relationship with P. duthiei and P. lachenense in the model-based analyses. The Kimura 2-parameter distances of the rbcL sequences between S. glaciale and P. duthiei and P. lachenense were 0.1 and 0.2%, respectively. Furthermore, S. glaciale differed from P. duthiei by a single nucleotide in their rbcL sequences. Close relationships between S. glaciale and P. duthiei and P. lachenense are also supported by the shared spore ornamentation with echinate fenestrate folds.

“…Wang et al (2004) proposed a subdivision of the Athyriaceae into five subfamilies: Cystopterioideae, Athyrioideae, Deparioideae, Diplazioideae and Rhachidosoroideae. Smith et al (2006) recognised the family Woodsiaceae, including Athyrioideae and Cystopterioideae, considering it premature to adopt so many small families, since their limits are poorly defined and there is no extensive phylogenetic analysis (Hasebe et al 1995;Sano et al 2000;Schneider et al 2004). Although most of the group is monophyletic (Schuettpelz & Pryer 2008), the two biggest genera, Athyrium and Diplazium, are likely not (Sano et al 2000;Wang et al 2003).…”

Kramer & Kato (1990) affirm that knowledge of the species of Diplazium is still insufficient and a broad study is necessary to propose a natural subdivision of the genus.…”
