The complete mitochondrial genome sequence of the black-capped capuchin (Cebus apella)
Provedor de dados: Genetics and Molecular Biology
Autores: Bi,Xiao-xin; Huang,Ling; Jing,Mei-dong; Zhang,Li; Feng,Pei-yong; Wang,Ai-yun.
The phylogenetic relationships of primates have been extensively investigated, but key issues remain unresolved. Complete mitochondrial genome (mitogenome) data have many advantages in phylogenetic analyses, but such data are available for only 46 primate species. In this work, we determined the complete mitogenome sequence of the black-capped capuchin (Cebus apella). The genome was 16,538 bp in size and consisted of 13 protein-coding genes, 22 tRNAs, two rRNAs and a control region. The genome organization, nucleotide composition and codon usage did not differ significantly from those of other primates. The control region contained several distinct repeat motifs, including a putative termination-associated sequence (TAS) and several conserved sequence...

The complete mitochondrial genome sequence of the little egret (Egretta garzetta)
Provedor de dados: Genetics and Molecular Biology
Autores: Zou,Yi; Jing,Mei-dong; Bi,Xiao-xin; Zhang,Ting; Huang,Ling.
Many phylogenetic questions in the Ciconiiformes remain unresolved and complete mitogenome data are urgently needed for further molecular investigation. In this work, we determined the complete mitogenome sequence of the little egret (Egretta garzetta). The genome was 17,361 bp in length and the gene organization was typical of other avian mtDNA. In protein-coding genes (PCGs), a C insertion was found in ND3, and CO III and ND4 terminated with incomplete stop codons (T). tRNA-Val and tRNA-Ser (AGY) were unable to fold into canonical cloverleaf secondary structures because they had lost the DHU arms. Long repetitive sequences consisting of five types of tandem repeats were found at the 3′ end of Domain III in the control region. A phylogenetic analysis of...

Evolutionary Origins of Rhizarian Parasites

Autores: Sierra, Roberto; Canas-duarte, Silvia J.; Burki, Fabien; Schwelm, Arne; Fogelqvist, Johan; Dixelius, Christina; Gonzalez-garcia, Laura N.; Gile, Gillian H.; Slamovits, Claudio H.; Klopp, Christophe; Restrepo, Silvia; Arzul, Isabelle; Pawlowski, Jan.
The SAR group (Stramenopila, Alveolata, Rhizaria) is one of the largest clades in the tree of eukaryotes and includes a great number of parasitic lineages. Rhizarian parasites are obligate and have devastating effects on commercially important plants and animals but despite this fact, our knowledge of their biology and evolution is limited. Here, we present rhizarian transcriptomes from all major parasitic lineages in order to elucidate their evolutionary relationships using a phylogenomic approach. Our results suggest that Ascetosporea, parasites of marine invertebrates, are sister to the novel clade Apofilosa. The phytomyxean plant parasites branch sister to the vampyrellid algal ectoparasites in the novel clade Phytorhiza. They also show that...

Phylogenetic position of the coral symbiont Ostreobium (Ulvophyceae) inferred from chloroplast genome data
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Verbruggen, Heroen; Marcelino, Vanessa R.; Guiry, Michael D.; Cremen, Ma. Chiela M.; Jackson, Christopher J.
The green algal genus Ostreobium is an important symbiont of corals, playing roles in reef decalcification and providing photosynthates to the coral during bleaching events. A chloroplast genome of a cultured strain of Ostreobium was available, but low taxon sampling and Ostreobium's early-branching nature left doubt about its phylogenetic position. Here, we generate and describe chloroplast genomes from four Ostreobium strains as well as Avrainvillea mazei and Neomeris sp., strategically sampled earlybranching lineages in the Bryopsidales and Dasycladales respectively. At 80,584 bp, the chloroplast genome of Ostreobium sp. HV05042 is the most compact yet found in the Ulvophyceae. The Avrainvillea chloroplast genome is similar to 94 kbp and contains...
