Short Abstract: Recently, the availability of genomic information from model organisms for evolutionary developmental biology studies have been increasing, such as the case of the colonial tunicate Didemnum vexillum, that represent an organism that have an invasive marine lifestyle. In their genomic and evolutionary context, Tunicates represent the sister group of Vertebrates and have remarkable genome organization and evolutionary patterns. With this evidence, we have been interested in the genome organization of the non-coding RNAs regions, that are characterized by their patterns of conservation in the secondary structure level in this genome. Through the analysis on the D. vexillum genome, we estimated both: a genome size about to 542.32 Mb distributed through 882185 fragments, and a GC content around 35.96%. Through the application of 8 different homology BLAST strategies we found homology regions with parameters of identity greater than 75%, compared with correspondent query sequences from a set of 11 different evolutionary related organisms dispersed along Metazoa. That searches revealing that the most homology hits comes from miRNA family. On the other way, the results of a Hidden Profile Markov Models (HMMs) strategy, suggest that about 80% of the obtained hits with this strategy, belongs to tRNAs, U6, miR-598 and Small Ribosomal Subunits. The validation of those candidates was achieved with structural alignments, applying different families of Covariance Models (CMs), obtaining possible non-redundant regions that correspond to a particular family of non-coding RNAs (ncRNAs). For each CM we measure quality parameters to recognize the better strategy searching the different families of ncRNAs. |

Short Abstract: Leaf rust is an important disease affecting wheat production in Brazil. Plant pathogen fungicide resistance demands discovery of new disease management control strategies, and improved genetic breeding is one such effective approach. This work presents Toropi-specific sequences that could represent new resistance candidate genes to be used in wheat breeding. |

Short Abstract: Eukaryotic AAA/FtsH proteases display a key role in the protein quality control of membrane-inserted proteins in mitochondria and chloroplasts. In Arabidopsis thaliana, chloroplast thylakoidal membranes FtsH proteases form a heterohexameric complex made by FtsH1/FtsH5 (type A) and FtsH2/FtsH8 (type B) subunits. This complex is involved in protein turnover of photo-damaged proteins, in particular the D1 protein at the PSII reaction center. Several lines of evidence also indicate that a FtsH threshold level is necessary for the proper formation and development of chloroplasts. Despite extensive genetic and molecular characterization of the FtsH proteases, the regulatory mechanism of the FtsH complex in chloroplasts has not yet been fully elucidated, however, there are evidences that its activation might be related to high light incidence and other stress conditions. The presence of auxiliary protein factors, as an alternative hypothesis, was tested by our group, through the use of the protease FtsH5 as bait in a yeast two-hybrid assay. This essay identified a putative interacting protein named FIP (FtsH5 Interacting Protein), which has been proved to interact with FtsH5 and be located at the thylakoid membranes. In order to shed some light on the evolutionary history of FtsH5 and FIP interacting proteins, we have shown that FIP’s homologous sequences were exclusively found in mosses and higher plants, suggesting that FIP origin might be related to the plant terrestrial colonization. All Arabidopsis FtsH-encoding genes were used as “query” sequences in search for homologous sequences, allowing us classify the FtsH proteases in type A and B by the complete phylogeny of the FtsH complex proteins. Bayesian phylogenetic analyses were run for FIP and FtsH types A and B proteases. Mirrortree analysis supported coevolution between FIP and type A FtsH proteases. On the other hand, no correlation was found between FIP and type B FtsH homologues, which support our previous experimental observations. In order to investigate a putative regulatory role of FIP on FtsH complex activity we analyzed gene expression patterns in a wide range of stress conditions from public DNA microarray data. The expression profiles indicate that FIP could be a negative regulator of the FtsH complex activity. The results also suggest that the complex may be involved in the chloroplast response to different types of stress conditions. Subsequent in-depth analyzes will further investigate the existence of selection sites on both interacting proteins. These results may provide a better understanding of the interaction of these proteins and how FIP drives FtsH type A proteases evolution. |

Short Abstract: Background: The amazon parrot (Amazona aestiva) belongs to the Psittacidae family, an interesting group of birds capable of vocal learning, intelligence and longevity. We have recently sequenced (1.3Gb, N50 1.2 Mb) and annotated (22,566 protein coding genes) the parrot genome and with this study we aim to investigate the genes possibly involved with longevity in birds. For this purpose, two curated databases were used: GenAge - collection of model organisms proteins involved with aging - and AnAge – maximum longevity data for several organisms. Results: A total of 1,792 sequences from GenAge were used in an orthologous search with orthoMCL in parrot and 12 other bird species, yielding 359 clusters with at least one sequence from all the analyzed birds. Based on maximum longevity recorded in captivity conditions acquired from AnAge, we created two groups, low-longevity (LL - 11 to 30 years) and high-longevity birds (HL - 31 to 50 years). In order to infer differential selective pressure acting on these genes, we used two methods: I- Ka/Ks comparisons (ratio of the number of non-synonymous substitutions per non-synonymous site (Ka) to the number of synonymous substitutions per synonymous site (Ks)) and II- site substitution model to detect specific codons under selection. For the first approach, coding DNA sequences were retrieved for each group and all against all pairwise PRANK alignments were performed between sequences from each longevity group. Ka/Ks ratios were estimated with KaKs_Calculator combining results of an approximate (Modified Yang and Nielsen) and a maximum-likelihood method (Goldman and Yang) and a t-test (alpha 0.01) was used to compare means. A total of 43 genes, involving both pro and anti-longevity activities, presented significantly different mean values, surprisingly 39 (90.7%) of which were greater on the HL group, meaning that they are under more relaxed selective pressure. Among them are i- Ubiquinol-Cytochrome c oxidoreductase complex (means LL:0.12, HL:0.19 +- 0.02) and ii- MRS2, mitochondrial RNA splicing (means LL:0.12, HL:0.23 +- 0.02). Among the four genes where the mean was smaller for HL birds are: i- Subunit of the NADH:ubiquinone oxidoreductase complex (means LL:0.10, HL:0.05 +- 0.01) and ii- Thioredoxin 1 (means LL:0.18, HL:0.10 +- 0.03). For the second approach, clusters were analyzed with PAML, comparing the likelihood values of a neutral (runmode=0, model=0 and NSites=1) against a positive selection model (runmode=0, model=0 and NSites=2) with LRT (Likelihood Ratio Test, pvalue=0.01). For only four clusters, not coincidents with the previous analysis, the positive selection was the best fitting model, in proteins such as superoxide dismutase and urokinase. Two positively selected codons (pvalue=0.01) were observed. Conclusions: Comparative analysis using distinct biological databases and evolutionary bioinformatic tools reveals interesting features regarding bird genes whose homologs in model organisms has been shown to be involved with longevity. |

Short Abstract: Poxviridae viruses infect vertebrate or invertebrate hosts and, therefore, represent an interesting long-term evolution scenario to study coevolutionary patterns of viruses to their hosts. We generated dinucleotide odds ratio for poxviruses and their hosts coding sequences and detected potential coevolutionary trends in CpG usage when comparing Orthoptera and its virus. |
