Wilsonosiphonia gen. nov. (Rhodomelaceae, Rhodophyta) based on molecular and morpho‐anatomical characters

Abstract

Morphological, anatomical, and molecular sequence data were used to assess the establishment and phylogenetic position of the genus Wilsonosiphonia gen. nov. Phylogenies based on rbcL and concatenated rbcL and cox1 loci support recognition of Wilsonosiphonia gen. nov., sister to Herposiphonia. Diagnostic features for Wilsonosiphonia are rhizoids located at distal ends of pericentral cells and taproot-shaped multicellular tips of rhizoids. Wilsonosiphonia includes three species with diagnostic rbcL and cox1 sequences, Wilsonosiphonia fujiae sp. nov. (the generitype), W. howei comb. nov., and W. indica sp. nov. These three species resemble each other in external morphology, but W. fujiae is distinguished by having two tetrasporangia per segment rather than one, W. indica by having abundant and persistent trichoblasts, and W. howei by having few and deciduous trichoblasts.

Analysis of chloroplast genomes and a supermatrix inform reclassification of the Rhodomelaceae (Rhodophyta)

“…Free rhizoids are the attachment structures of most Rhodomelaceae, while basal discs have evolved in the largest species. Although rhizoids are small structures, they are morphologically very variable, as previously described (e.g., Hollenberg 1967, Womersley 2003, Zuccarello and West 2006, Bustamante et al 2017; Fig. 2).…”

Molecular Assisted Identification Reveals Hidden Red Algae Diversity from the Burica Peninsula, Pacific Panama

“…Taylor [2] also refered Pacific Panama specimens collected from Isla Taboga in the Bay of Panama to this species, and it has been widely reported in warm-temperate and tropical waters since then e.g., [90,[103][104][105]. Mamoozadeh and Freshwater [95] suggested that the concept of W. howei (as Polysiphonia howei) encompassed multiple species based on reported variation in spermatiagial branch development e.g., [104,106,107], pericentral cell numbers e.g., [44,90], and divergence between available nuclear-encoded 18S rRNA gene sequences.…”

Bustamante et al [103] included two new species in Wilsonosiphonia when they described the genus, W. fujiae D. Bustamante, Won and T.O. Cho, the generitype, and W. indica D. Bustamante, Won and T.O.…”

Characterization of the complete mitochondrial genome of the black Alpaca breed of Vicugna pacos (Mammalia, Artiodactyla, Camelidae) from Puno, Peru

“…The 150 bp PE Illumina library construction and sequencing was performed by myGenomics, LLC (Alpharetta, Georgia, USA). The genomes were assembled using default de novo settings in MEGAHIT (Li et al 2016) and Sanger sequencing to close the gap in the control region using primers 16,107 F 5 0 -CCCGCATCATACAACCATAAGG-3 0 and 48 R 5 0 -CCATCT AGGCATTTTCAGCGC-3 0 following the protocol of Bustamante et al (2017). The mitogenome was confirmed using default mapping settings in Geneious Prime (Biomatters, Ltd, Auckland, New Zealand).…”
