The prevailing view of the nuclear genetic code is that it largely frozen and unambiguous. Flexibility in has been demonstrated ciliates reassign standard stop codons to amino acids, resulting seven variant codes, including three previously undescribed ones reported here. Surprisingly, two these species, we find efficient translation all 64 as acids recognition either one or codons. How, therefore, does machinery interpret a "stop" codon? We provide evidence, based on ribosomal profiling...
The order Rickettsiales (Alphaproteobacteria) encompasses multiple diverse lineages of host-associated bacteria, including pathogens, reproductive manipulators, and mutualists. Here, in to understand how intracellularity host association originated this order, whether they are ancestral or convergently evolved characteristics, we built a large phylogenetically-balanced dataset that includes de novo sequenced genomes selection published genomic metagenomic assemblies. We perform detailed...
The littoral forest on sandy soil is among the most threatened habitats in Madagascar and, as such, it represents a hot-spot within conservation hot-spot. Assessing health of resident lemur fauna not only critical for long-term viability these populations, but also necessary future re-habilitation this unique habitat. Since Endangered collared brown lemur, Eulemur collaris, largest seed disperser Malagasy south-eastern its survival habitat crucial. In study we compared fecal glucocorticoid...
Taxonomy is the science of defining and naming groups biological organisms based on shared characteristics and, more recently, evolutionary relationships. With birth novel genomics/bioinformatics techniques increasing interest in microbiome studies, a further advance taxonomic discipline appears not only possible but highly desirable. The present work proposes new approach to modern taxonomy, consisting inclusion descriptors organism characterization: (1) presence associated microorganisms...
Holospora spp. and "Candidatus Gortzia infectiva", known as Holospora-like bacteria (HLB), are commonly found nuclear endosymbionts of ciliates, especially the Paramecium genus. HLB related by phylogenetic relationships, morphological features, life cycles, which involve two alternating morphotypes: reproductive infectious forms (RF, IF). In this paper we describe a novel species belonging to "Ca. Gortzia" genus, detected in P. multimicronucleatum, ciliate for infection an has not been...
The increasing global population and the simultaneous growing attention to natural, sustainable, healthier products are driving food industry towards research on alternative sources. In this scenario, microalgae gaining worldwide as "functional feedstocks" for foods, feeds, supplements, nutraceutical formulations, being a source of high-value metabolites including polyphenols other antioxidant compounds. work, eleven microalgal strains from freshwater environments were evaluated their...
Chaetonotidae is the most diversified family of entire phylum Gastrotricha; it comprises ~430 species distributed across 16 genera. The current classification, established mainly on morphological traits, has been challenged in recent years by phylogenetic studies, indicating that cuticular ornamentations used to discriminate among may be misleading when identify groupings, which practice until now. Therefore, a consensus developing toward implementing novel approaches better define identity...
Three controlled water supply treatments were applied to 1-year-old peach trees grown in root observation boxes. The were: I(0), growth medium maintained at 50% field capacity; I(1), supplied when daily net tree stem diameter change was negative or zero for 1 day; I(3) as I(1) except that after 3 consecutive days. Trees treatment I(0) had the greatest mean first-order shoot rates, and lowest rates. Because leaf production rate (apparent plastochron) of shoots unaffected by treatment,...
Abstract The subclass Peniculia (Oligohymenophorea, Intramacronucleata) is one of the most known groups phylum Ciliophora, being composed by very notorious representatives, such as Paramecium and Frontonia . Nevertheless, phylogenetic relationships among genera within this are still far from resolved. Moreover, for several members group characterization molecular markers lacking, Wenrichia, Clathrostoma, Paraclathrostoma, Didieria and, to date, also Neobursaridium finding strain gigas India...
Abstract While the drivers of primate persistence in forest fragments have been often considered at population level, strategies to persist these habitats little investigated individual or group level. Considering rapid variation fragment characteristics over time, longitudinal data on primates living fragmented are necessary understand key elements for their persistence. Since translocated animals cope with unfamiliar areas and face unknown fluctuations food abundance, they offer...
Most of the microorganisms responsible for vector-borne diseases (VBD) have hematophagous arthropods as vector/reservoir. Recently, many new species phylogenetically related to agents VBD were found in a variety aquatic eukaryotic hosts; particular, numerous bacterial genus Rickettsia ( Alphaproteobacteria , Rickettsiales ) discovered protist ciliates and other unicellular eukaryotes. Although their pathogenicity humans terrestrial animals is not known, several indirect indications exist...
Hamatopeduncularia was erected with Hamatopeduncularis arii as the type species. This genus comprises monogenoidean species mostly found ectoparasites of marine catfishes belonging to Ariidae. There is a significant taxonomic ambiguity among due their morphological similarity, but so far only few studies have succeeded in addressing interspecific variation and relationships. Moreover, little molecular data available for this genus. A multidisciplinary, integrated study consisting...
Abstract In 1991 Margulis defined holobionts as the assemblage of “two or more organisms, members different species” which remain associate “throughout a significant portion life history”. recent times, have been described among many and far-related groups living beings, such plants, algae, insects, corals, even humans. These studies arisen an increasing interest in contexts but, to our knowledge, holobiont concept has not applied taxonomy. Here we propose new approach modern taxonomy, aimed...
Among Oligohymenophorea (Ciliophora, Alveolata) the subclass Peniculia stands as one of most well-known groups. Frontonia is largest genus Peniculia, and its representatives are spread in any type water bodies well soil. At a first glance, species exhibit an overall similar morphology, form well-recognizable taxon ciliates. Despite general morphological homogeneity, phylogenetic analysis based on 18S rDNA sequencing showed that non-monophyletic group. The systematics this should be deeply...
