title: Replication Data for: A light, chondritic xenolith in the Murchison (CM) chondrite – Formation by fluid-assisted percolation during metasomatism?

description: Abstract: The main mineralogical characteristics of a large light-colored clast within the Murchison CM breccia are discussed in detail including data on the mineralogy, bulk chemistry, organics, and oxygen isotopes. Petrographic study shows that the white clast consists of two areas with different granoblastic textures: (1) a coarse-grained (average grain size: ∼200 μm) and (2) a fine-grained lithology (average grain-size: ∼20 μm). The Fa-content of olivine in the clast is the same as Fa within olivine from Rumuruti (R) chondrites (Fa: ∼38 mol%); however, the concentrations of the elements Ni and Ca in olivine are significantly different. The fragment also contains Ca-rich pyroxene, ∼An30-38-plagioclase/maskelynite, Cr-rich spinel, several sulfide phases, a nepheline-normative glass, and traces of merrillite and metal. The occurrence of maskelynite and nepheline-normative amorphous phase in restricted areas of the well-recrystallized rock may indicate remarkable P-T-excursions during shock metamorphism. The O-isotope composition of the clast falls below the terrestrial fractionation line (TFL), lying in the field of CM chondrites and is significantly different from data for bulk R chondrites. The study of the soluble organic matter revealed a highly-oxidized carbon chemistry and organomagnesium compounds reflecting high temperature and pressure processes.

title: First draft of an annotated genome for a lichenised strain of the green alga <i>Diplosphaera chodatii</i> (Prasiolales, Trebouxiophyceae)

description: Although genome sequences of lichenized fungi are increasingly becoming available, genome sequences of microalgae involved in the lichen symbiosis are still scarce. For lichenized eukaryotic algae, genome sequencing has focused mostly on <i>Trebouxia</i> and <i>Asterochloris</i>, with little genomic data available for <i>Stichococcus</i>-like algae, such as <i>Diplosphaera</i>. The genus <i>Diplosphaera</i> is a common component of biological soil crusts, and often occurs associated with lichens of the family Verrucariaceae. It is characterized by cylindrical to spherical cells containing a plate-like chloroplast, and more specifically by a vegetative cell division that leads to the formation of typical two- to four-celled clusters. Here, we present a draft genome sequence for the algal partner of an Australian lichen specimen of <i>Endocarpon pusillum</i>. The genome was sequenced with Pac Bio long read and Illumina short read technologies, and transcriptome data were generated to inform the structural annotations. This algal strain is here identified as <i>Diplosphaera chodatii</i> based on nuSSU and ITS data. Compared with closely related lichenized and non-lichenized algae, the genome of <i>D. chodatii</i> stands out for its large size (85.6 Mb) and gene content (21,261 protein-encoding regions), as well as its high rate of duplicated genes (60% of the BUSCO genes are duplicated). These results suggest that whole genome duplication or large-scale segmental duplications may have occurred in the evolutionary history of this algal species. Little genome data are available for lichenized algae.We generated the first genome for a lichenized <i>Diplosphaera chodatii</i>.Results suggest a possible whole genome duplication in this species.

title: Diversity of the genus <i>Avrainvillea</i> (Dichotomosiphonaceae, Chlorophyta): new insights and eight new species

description: <i>Avrainvillea</i> is a green macroalgal genus of the family Dichotomosiphonaceae (order Bryopsidales). Many species have been morphologically described, but few studies have addressed the genetic diversity of this genus. Based on a rich collection of specimens from the tropical Western Atlantic, Indian and Pacific Oceans, we aimed to (1) reassess <i>Avrainvillea</i> species diversity through species delimitation analyses, (2) update their distribution ranges, (3) reconstruct the species phylogenetic relationships, based on a concatenated multilocus matrix (<i>tuf</i>A, <i>rbc</i>L and 18S rDNA) and (4) revise their taxonomy and describe new species where necessary. Our species delimitation approach highlighted 23 secondary species hypotheses in our collection, including nine known and currently accepted species, four species complexes (<i>A. amadelpha, A. lacerata, A. erecta-obscura</i> and <i>A. mazei-nigricans</i>), and eight new species for which we provide descriptions: <i>A. laciniata</i> (Papua New Guinea), <i>A. minima</i> and <i>A. pyrochroma</i> (Madagascar), <i>A. mollis</i> and <i>A. kanakiensis</i> (New Caledonia), <i>A. pavonina</i> (Fiji), <i>A. spongiosa</i> (Pacific) and <i>A. corticata</i> (Indo-Pacific). We also propose the resurrection of <i>A. gracillima</i> Børgesen, the reinstatement of <i>Avrainvillea lacerata</i> var. <i>robustior</i> A.Gepp & E.S.Gepp, and the synonymy of <i>A. rotumensis</i> A.D.R.N’Yeurt, D.S.Littler & Littler with <i>A. pacifica</i> A.Gepp & E.S.Gepp. We complemented the taxonomic work by providing a contemporary dichotomous key for morphological identification of all extant species. Our multilocus phylogeny included 25 species of Dichotomosiphonaceae and recovered <i>Avrainvillea</i> as a polyphyletic group, divided into three distinct clades, with <i>Cladocephalus luteofuscus</i> positioned within the group. The species determined using the species delimitation approach were all monophyletic and 19 of them were highly supported. For the first time, this study also provided genetic sequences for <i>A. asarifolia, A. clavatiramea, A. digitata, A. elliottii, A. fulva, A. gracillima, A. geppiorum, A. pacifica</i> and <i>A. obscura</i>. • <i>Avrainvillea</i> is not monophyletic.• Reassessment of <i>Avrainvillea</i> species diversity delimited 23 secondary species hypotheses.• Eight new species of <i>Avrainvillea</i> were discovered in the Indo-Pacific. • <i>Avrainvillea</i> is not monophyletic. • Reassessment of <i>Avrainvillea</i> species diversity delimited 23 secondary species hypotheses. • Eight new species of <i>Avrainvillea</i> were discovered in the Indo-Pacific.

title: Morphological and molecular investigations shed light on diversity and distribution of Palmariaceae in the north-western Pacific

description: Traditional morphology-based investigations of the red algal genera <i>Devaleraea</i> and <i>Palmaria</i> (Palmariaceae, Rhodophyta) fail to provide accurate accounts of diversity and distribution for species from the Russian coast of the north-western Pacific. Consequently, there is much disagreement and taxonomic uncertainty regarding several species. To resolve these issues we conducted a molecular-assisted investigation that included a DNA barcode survey (COI-5’) and multilocus (COI-5’, cob, <i>psa</i>A, ITS) phylogenetic analyses. Our analyses indicate that diversity was previously underestimated for the <i>Devaleraea</i>/<i>Palmaria</i> complex. We describe three additional species of <i>Devaleraea: D. sakhalinensis</i> sp. nov., <i>D. kussakinii</i> sp. nov. and <i>D. urupiana</i> sp. nov. We consider <i>D. titlyanoviorum</i> to be an alga with abundant proliferations from the margins, branching to several orders, that is known only from Kunashir Island. Algae from Sakhalin Island and the mainland coast of the Sea of Japan previously identified as <i>D. titlyanoviorum</i> are described here as <i>D. sakhalinensis</i>. We confirmed that the genus <i>Palmaria</i> is not monotypic. It includes at least two species: <i>P. palmata</i> in the North Atlantic and <i>P. moniliformis</i> in the north-western Pacific. We expand the known ranges of <i>D. callophylloides, D. mollis</i> and <i>P. hecatensis</i> in the north-western Pacific southwards and find that <i>D. stenogona</i> is confined to the northern part of the Sea of Japan. The distribution patterns of species of the genera <i>Devaleraea</i> and <i>Palmaria</i> are discussed in relation to the oceanography of the north-western Pacific. Three new species of the genus <i>Devaleraea</i> are proposed.The genus <i>Palmaria</i> is not monotypic and includes at least two species, <i>P. moniliformis</i> and <i>P. palmata.</i> Three new species of the genus <i>Devaleraea</i> are proposed.

title: Taxonomic revision of <i>Tinocladia</i> (Ectocarpales <i>s.l</i>., Phaeophyceae): merger of <i>Tinocladia</i> with <i>Eudesme</i> and description of <i>E. pseudocrassa</i> sp. nov

description: A molecular phylogeny of <i>Tinocladia</i> and <i>Eudesme</i> based on specimens covering a large proportion of the known species was done using mitochondrial <i>cox</i>1 and <i>cox</i>3, chloroplast <i>atp</i>B, <i>psa</i>A, <i>psb</i>A and <i>rbc</i>L genes and 5.8S rDNA and its ITS2 region sequences. The phylogeny revealed a close phylogenetic relationship between the two genera and the occurrence of a cryptic species within the generitype <i>T. crassa. Eudesme</i> species (<i>E. borealis, E. shandongensis</i> and the generitype <i>E. virescens</i>) showed a sister relationship with the northern hemisphere <i>Tinocladia</i> (<i>T. crassa</i>, including a cryptic sister species <i>T. pseudocrassa</i> sp. nov., and <i>T. sanrikuensis</i>), whereas southern hemisphere <i>Tinocladia</i> (<i>T. australis, T. falklandica, T. novae-zelandiae</i>, and a cryptic species from New Zealand) nested in the <i>Eudesme</i> clade. Morphologically, <i>Tinocladia</i> species have been distinguished from <i>Eudesme</i> by their denser medullary filaments and more extensive subcortical layer, but our molecular phylogenetic analyses suggest that these features do not correlate with genetic differences. The <i>cox</i>3 sequence divergence between northern hemisphere <i>Tinocladia</i> and the lineage that includes <i>Eudesme</i> and southern hemisphere <i>Tinocladia</i> was comparable to or smaller than those within selected ectocarpalean genera. We therefore propose to merge <i>Tinocladia</i> with <i>Eudesme</i> and resurrect <i>Eudesme crassa</i> (Suringar) Okamura for <i>T. crassa</i>. Although the two independent lineages of <i>T. crassa</i> do not show marked morphological differences, they are genetically isolated even in sympatric populations. We therefore propose to treat them as independent species. In this paper we neotypify <i>Tinocladia crassa</i> (=<i>Eudesme crassa</i>), describe <i>E. pseudocrassa</i> sp. nov., and determine that the Californian population of <i>E. crassa</i> is an introduction from Northeast Asia. <b>HIGHLIGHTS</b> •A taxonomic revision of <i>Eudesme</i> and <i>Tinocladia</i>, based on genetic and morpho-anatomy, provides evidence to merge <i>Tinocladia</i> with <i>Eudesme</i>. •The finding of cryptic species in New Zealand highlights the need for further taxonomic studies in this region. •The genetic data have revealed the occurrence of a cryptic species within <i>T. crassa</i> in Japan.

title: Freezing and desiccation tolerance in the Antarctic bangiophyte <i>Pyropia endiviifolia</i> (Rhodophyta): a chicken and egg problem?

description: Antarctic macroalgal communities of the upper intertidal zone are particularly poor compared with other coastal regions. Exposure to desiccation and freezing combined with the abrasive effect of ice threatens the life of sessile organisms. One of the few species able to colonize this environment is the rhodophyte <i>Pyropia endiviifolia</i>. It belongs to the Bangiales, one of the oldest extant clades of photosynthetic eukaryotes, which has occurred for more than one billion years with basically the same morphological structure. Considering that the extent of Antarctic glaciation is a geologically recent event, we hypothesized that pre-adaptations to desiccation in bangiophytes may have contributed to the success of <i>P. endiviifolia</i> in Antarctica. To test this, we compared its photosynthetic performance and tolerance to desiccation and freezing with those from a related intertidal species, the temperate Atlantic species <i>Porphyra linearis</i>. As evidenced by gas exchange and chlorophyll fluorescence, <i>P. endiviifolia</i> is more adapted to high irradiances than <i>P. linearis</i>. The former species was also more desiccation-tolerant, and showed a higher glass transition temperature. Both species did not differ in chlorophyll content per dry weight, and tolerance to −20°C, even though the ice-nucleation temperature was much higher in <i>P. endiviifolia</i>. Membrane integrity may depend on fatty acid composition in <i>P. endiviifolia</i>, while on enhanced tocopherol in <i>P. linearis</i>. Overall, both species show different strategies to deal with freezing temperatures: supercooling in <i>P. linearis</i> vs. freezing-tolerance in <i>P. endiviifolia</i>. This matches with the probability of being subjected to sub-zero temperatures in their natural environments (lower in the case of <i>P. linearis</i>). Surprisingly, the higher risk of dehydration in the natural habitat of <i>P. linearis</i> is not matched by a higher desiccation tolerance. This observation does not support the initial hypothesis of the study but suggests the opposite: the acclimation to a cold environment results in higher desiccation tolerance. HIGHLIGHTS ● <i>Porphyra linearis</i> and <i>Pyropia endiviifolia</i> are remarkably tolerant to desiccation and freezing.● Antarctic <i>P. endiviifolia</i> is remarkably tolerant to desiccation and freezing.● Mechanisms of freezing tolerance could induce a higher tolerance to desiccation.
