In recent years, the use of molecular data in algal systematics has increased as high-throughput sequencing (HTS) become more accessible, generating very large datasets at a reasonable cost. this perspectives paper, our goal is to describe how HTS technologies can advance systematics. Following an introduction some common technologies, we discuss metabarcoding accelerate species discovery. We show various methods be applied generate for accurate delimitation, and historical type specimens...
Abstract Morphological identification of species in the order Gelidiales can be difficult and controversial because phenotypic plasticity, low numbers reproductive specimens poorly defined taxonomic boundaries. A DNA barcoding survey Brazilian Gelidiales, employing neighbor-joining Automatic Barcode Gap Discovery analyses, indicated presence 23 statistically robust primary hypotheses (PSH). In addition to cytochrome oxidase I gene (COI-5P), chloroplast universal plastid amplicon (UPA) marker...
Gracilariales is a clade of florideophycean red macroalgae known for being the main source agar. We present de novo genome assembly and annotation Gracilaria domingensis , an agarophyte alga with flattened thallus widely distributed along Central South American Atlantic intertidal zones. In addition to structural analysis, organizational comparison was done other Rhodophyta genomes. The nuclear has 78 Mbp, 11,437 predicted coding genes, 4,075 which did not have hits in sequence databases....
Gracilariaceae has a worldwide distribution including numerous economically important species. We applied high‐throughput sequencing to obtain organellar genomes (mitochondria and chloroplast) from 10 species of and, combined with published genomes, infer phylogenies compare genome architecture among representing main lineages. obtained similar topologies between chloroplast mitochondrial phylogenies. However, the phylogeny was better resolved full support. In this phylogeny, Melanthalia...
:Seven species of the economically important agarophyte genus Pterocladiella were previously reported from Brazil: P. australafricanensis, bartlettii, beachiae, caerulescens, capillacea, sanctarum and taylorii. Only beachiae capillacea confirmed by molecular data. This study surveyed Brazil using both morphological analyses. DNA bar coding phylogenetic analyses carried out with mitochondrial COI-5P plastid rbcL markers. Both data presence five in a new record media. bartlettii are common...
Endosymbiosis, the establishment of a former free-living prokaryotic or eukaryotic cell as an organelle inside host cell, can dramatically alter genomic architecture endosymbiont. Plastids chloroplasts, light-harvesting photosynthetic eukaryotes, are excellent models to study this phenomenon because plastid origin has occurred multiple times in evolution. Here, we investigate signature molecular processes acting through secondary endosymbiosis-the origination new from alga. We used...
Because of phenotypic plasticity, undefined specific boundaries, and specimens that are rarely fertile, species recognition in Gelidiales has been extremely difficult controversial. Fifteen Gelidiellaceae Gelidiaceae have reported Brazil with the majority regional floristic studies or lists. Thus, not received enough attention Brazil, many taxonomic problems remain unresolved. In this study, an integrative systematic approach based on morphology vegetative reproductive structures two...
:Gelidium coarctatum Kützing was a poorly known species described from the coast of Brazil. The name picked up by Ugadim and applied to common on tropical Brazil coast. Analyses partial rbcL sequences morphological characters G. holotype have shown that it is synonym Gelidium capense (Gmelin) P.C.Silva had been misapplied in latter as lineare sp. nov., characterized externally determinate lateral branches giving axes generally linear outline internally copious rhizines being concentrated...
Summary The genomic diversity underpinning high ecological and species in the green algae (Chlorophyta) remains little known. Here, we aimed to track genome evolution Chlorophyta, focusing on loss gain of homologous genes, lineage‐specific innovations core Chlorophyta. We generated a high‐quality nuclear for pedinophyte YPF701, sister lineage others Chlorophyta incorporated this comparative analysis with 25 other genomes from diverse Viridiplantae taxa. YPF701 has an intermediate size gene...
Abstract Giant kelp, Macrocystis pyrifera , is a foundation species that forms dense forests of complex physical habitat and supports coastal biodiversity, productivity, other essential ecosystem services. Tasmanian coasts have suffered massive decline in giant kelp due to changes regional oceanography environmental conditions, but efforts are being made restore these disappearing populations using identification selective breeding for lineages more tolerant warmer temperatures. Here, we...
DNA sequence analyses have demonstrated that Gelidium as currently circumscribed is not monophyletic and has three distinctive lineages: sensu stricto includes the generitype corneum, Capreolia group, another lineage two distinct clades formed by species from eastern Pacific western Atlantic Oceans. A new genus of small gelidioid algae, Gelidiorariphycus, described to accommodate one in this latter lineage. Four (Gelidiorariphycus loratus, G. gahunbooi, stipitatus sungminbooi) segregated...
Summary The green alga Ostreobium is an important coral holobiont member, playing key roles in skeletal decalcification and providing photosynthate to bleached corals that have lost their dinoflagellate endosymbionts. lives the coral’s skeleton, a low-light environment with variable pH O□ availability. We present nuclear genome metatranscriptomic analysis of healthy improve our understanding ’s adaptations its extreme as member. has 10,663 predicted protein-coding genes shows for life low...

Macrocystis pyrifera is a foundation species that creates kelp forests and supports essential ecosystem services across coastal environments. Over the past half-century, more than 95% of giant have declined around Tasmania Australia due to climate change, causing near-complete loss ecosystems they support. Compared with northern hemisphere ecosystems, Australian populations received little research attention in genomic other genetic analyses. We present complete mitochondrial chloroplast...
