AbstractLTR-retrotransposons are structurally similar to retroviruses, as they possess the enzymes reverse transcriptase, Ribonuclease H, integrase, proteinase, and the gag gene and are flanked by long terminal repeats (LTRs). The 412/mdg1 lineage, belonging to the Ty3/Gypsy group, consists of the TEs 412, mdg1, stalker, pilgrim, and blood. The 412/mdg1 lineage is distinguished from the others in the gypsy group in that it has small ORFs at the beginning of the TE and is highly similar to the pol ORF among the TEs that make up the lineage. In this study, our aim was to elucidate the evolutionary history of the 412/mdg1 lineage in the 127 dipteran genomes available to date, and the characteristics of the sequences in each genome. We used the canonical TE 412 probe described in Drosophila melanogaster as the query. We found sequences homologous to the 412/mdg1 lineage restricted to the suborder Brachycera. These sequences are widely distributed in drosophilids but are also present in other groups of flies. We note the presence of the 412/mg1 lineage in tsetse flies (Glossina). Furthermore, our results showed an elaborate evolutionary history for the pol ORF in the 412/mdg1 lineage of the LTR-Retrotransposon.

Virion Formation

The family Belpaoviridae comprises metazoan-infecting reverse-transcribing viruses with long terminal repeats, commonly known as Bel/Pao LTR retrotransposons. These viruses share evolutionary history and genes involved in genome replication and virion formation with reverse-transcribing viruses of the families Metaviridae, Pseudoviridae, Retroviridae and Caulimoviridae. These five families form the order Ortervirales. This is a summary of the ICTV Report on the family Belpaoviridae, which is available at ictv.global/report/belpaoviridae.

AbstractIntuitions guide decision-making, and looking to the evolutionary history of humans illuminates why some behavioral responses are more intuitive than others. Yet a place remains for cognitive processes to second-guess intuitive responses – that is, to be reflective – and individual differences abound in automatic, intuitive processing as well.
