The Last Common Ancestor: What's in a name?
TLDR
Dead-type RNA helicase and enolase genes are as conserved as many transcription and translation genes, suggesting the early evolution of a control mechanism for gene expression at the RNA level, providing additional support to the hypothesis that during early cellular evolution RNA molecules played a more prominent role. Expand
Genome and transcriptome analysis of the Mesoamerican common bean and the role of gene duplications in establishing tissue and temporal specialization of genes
TLDR
The genome and transcriptome data generated for a Mesoamerican genotype represent a counterpart to the genomic resources already available for the Andean gene pool, and will allow the genetic dissection of the characters involved in the domestication and adaptation of the crop, and their further implementation in breeding strategies. Expand
The Genomes of Three Uneven Siblings: Footprints of the Lifestyles of Three Trichoderma Species
TLDR
A broad, comprehensive overview of the genomic content of these species for “hot topic” research aspects, including CAZymes, transport, transcription factors, and development, along with a detailed analysis and annotation of less-studied topics, such as signal transduction, genome integrity, chromatin, photobiology, or lipid, sulfur, and nitrogen metabolism. Expand
Molecular Evolution of Peptide Methionine Sulfoxide Reductases (MsrA and MsrB): On the Early Development of a Mechanism That Protects Against Oxidative Damage
TLDR
Phylogenetic analyses of methionine sulfoxide reductases suggest that their distribution is the outcome of a complex history including many paralogy and lateral gene transfer events. Expand
Endophytes versus biotrophic and necrotrophic pathogens—are fungal lifestyles evolutionarily stable traits?
TLDR
It is concluded that biotrophy usually represents a derived and evolutionarily stable trait, whereas fungi easily can switch between an endophytic and necrotrophic lifestyle at the evolutionary and even the ecological timescale. Expand
Global Transcriptome Analysis of the Scorpion Centruroides noxius: New Toxin Families and Evolutionary Insights from an Ancestral Scorpion Species
TLDR
The results obtained in this report represent the first high-throughput study that thoroughly describes the universe of genes that are expressed in the scorpion Centruroides noxius Hoffmann, a highly relevant organism from medical and evolutionary perspectives. Expand
The Very Early Stages of Biological Evolution and the Nature of the Last Common Ancestor of the Three Major Cell Domains
TLDR
Although the gene complement of the cenancestor includes sequences that may have originated in different epochs, the extraordinary conservation of RNA-related sequences supports the hypothesis that the last common ancestor was an evolutionary outcome of the so-called RNA/protein world. Expand
Genomic history of the origin and domestication of common bean unveils its closest sister species
TLDR
An unpredicted speciation event in the tropical Andes that gave rise to a sibling species, formerly considered the “wild ancestor” of P. vulgaris, is uncovered and haplotypes strongly associated with genes underlying the emergence of domestication traits are identified. Expand
Species in Wolbachia? Proposal for the designation of 'Candidatus Wolbachia bourtzisii', 'Candidatus Wolbachia onchocercicola', 'Candidatus Wolbachia blaxteri', 'Candidatus Wolbachia brugii',
TLDR
Although all analyses indicated that each Wolbachia supergroup represents a distinct evolutionary lineage, it was found that some of the analyzed supergroups showed enough internal heterogeneity to be considered as assemblages of more than one species and supergroups would represent supraspecific groupings. Expand
Plant Proteins Are Smaller Because They Are Encoded by Fewer Exons than Animal Proteins
TLDR
It is concluded that plants have proteins larger than bacteria but smaller than animals or fungi, suggesting that photosynthetic organisms are unique and deserve therefore special attention with regard to the evolutionary forces acting on their genomes and proteomes. Expand
