Diversity and oceanic distribution of the Parmales (Bolidophyceae), a picoplanktonic group closely related to diatoms.

ABSTRACT: Bolidomonas is a genus of picoplanktonic flagellated algae that is closely related to diatoms. Triparma laevis, a species belonging to the Parmales, which are small cells with a siliceous covering, has been shown to form a monophyletic group with Bolidomonas. We isolated several novel strains of Bolidophyceae that have permitted further exploration of the diversity of this group using nuclear, plastidial and mitochondrial genes. The resulting phylogenetic data led us to formally emend the taxonomy of this group to include the Parmales within the Bolidophyceae, to combine Bolidomonas within Triparma and to define a novel species, Triparma eleuthera sp. nov. The global distribution of Bolidophyceae was then assessed using environmental sequences available in public databases, as well as a large 18S rRNA V9 metabarcode data set from the Tara Oceans expedition. Bolidophyceans appear ubiquitous throughout the sampled oceans but always constitute a minor component of the phytoplankton community, corresponding to at most ~4% of the metabarcodes from photosynthetic groups (excluding dinoflagellates). They are ~10 times more abundant in the small size fraction (0.8-5??m) than in larger size fractions. T. eleuthera sp. nov. constitutes the most abundant and most widespread operational taxonomic unit (OTU) followed by T. pacifica, T. mediterranea and the T. laevis clade. The T. mediterranea OTU is characteristic of Mediterranean Sea surface waters and the T. laevis clade OTU is most prevalent in colder waters, in particular off Antarctica.

Project description:The most striking feature of life is biodiversity. However, mechanisms of biodiversity remain poorly understood, as most protein orthologues of different species are highly homologous in sequence and identical in function. Interestingly, recent evidence has demonstrated heterogeneity for a G protein-coupled angiotensin II (Ang II) type 2 (AT(2)) receptor in both ligand binding and induction of arachidonic acid (AA) release. The present study investigated the properties of AT(2) receptors in closely related species.AT(2) receptors cloned from human, rabbit, rat, and mouse were expressed in Chinese hamster ovary cells (CHO-K1), African green monkey kidney cells (COS-1), and human embryonic kidney (HEK)-293 cells and characterized in ligand binding and signal transductions. Critical residues in rabbit AT(2) receptor attributable to heterogeneity were examined using both gain-of-function and loss-of-function approaches with mutagenesis.The newly cloned rabbit AT(2) receptor exhibits distinct biochemical and biologic properties compared to its highly homologous orthologues (91% in overall amino acid sequence) of rat, mouse, and human. All these orthologues activate SH2 domain-containing phosphatase-1 (SHP-1) and show similar binding affinities for Ang II and AT(2)-specific ligands CGP42112A and PD123319. However, reducing agent dithiothreitol (DTT) inactivates the rabbit orthologue but potentiates the others in ligand binding, a hallmark of AT(2) versus AT(1) receptor subtypes. Most interestingly, rabbit AT(2) receptor, but not the other orthologues, induces AA release in various cell systems when stimulated by both Ang II and CGP42112A, the peptide antagonist. Mutagenesis studies and sequence analyses further indicate that residues His(106), Asp(188), and Thr(293) are responsible for the DTT inactivation and residues Val(209) and Val(249) are partially responsible for AA release.These results deny the coexistence of an additional AT(2) subtype in rabbit proximal tubule cells and demonstrate for the first time the presence of functional diversity for closely related Eutherian orthologues of a G protein-coupled receptor (GPCR) that are more than 90% homologous in the amino acid sequence.

Project description:Genetic diversity defines the evolutionary potential of a species, yet mounting evidence suggests that epigenetic diversity could also contribute to adaptation. Elucidating the complex interplay between genetic and epigenetic variation in wild populations remains a challenge for evolutionary biologists, and the intriguing possibility that epigenetic diversity could compensate for the loss of genetic diversity is one aspect that remains basically unexplored in wild plants. This hypothesis is addressed in this paper by comparing the extent and patterns of genetic and epigenetic diversity of phylogenetically closely related but ecologically disparate species. Seven pairs of congeneric species from Cazorla mountains in south-eastern Spain were studied, each pair consisting of one endemic, restricted-range species associated to stressful environments, and one widespread species occupying more favourable habitats. The prediction was tested that endemic species should have lower genetic diversity due to population fragmentation, and higher epigenetic diversity induced by environmental stress, than their widespread congeners. Genetic (DNA sequence variants) and epigenetic (DNA cytosine methylation variants) diversities and their possible co-variation were assessed in three populations of each focal species using amplified fragment length polymorphism (AFLP) and methylation-sensitive AFLP (MSAP). All species and populations exhibited moderate to high levels of genetic polymorphism irrespective of their ecological characteristics. Epigenetic diversity was greater than genetic diversity in all cases. Only in endemic species were the two variables positively related, but the difference between epigenetic and genetic diversity was greater at populations with low genetic polymorphism. Results revealed that the relationship between genetic and epigenetic diversity can be more complex than envisaged by the simple hypothesis addressed in this study, and highlight the need of additional research on the actual role of epigenetic variation as a source of phenotypic diversity before a realistic understanding of the evolutionary relevance of epigenetic phenomena in plant adaptation can be achieved.
