Abstract
Mobile elements within genomes have driven genome evolution in diverse ways. Particularly in plants and mammals, retrotransposons have accumulated to constitute a large fraction of the genome and have shaped both genes and the entire genome. Although the host can often control their numbers, massive expansions of retrotransposons have been tolerated during evolution. Now mobile elements are becoming useful tools for learning more about genome evolution and gene function.

The chloroplast genomes of Bryopsis plumosa and Tydemania expeditiones (Bryopsidales, Chlorophyta): compact genomes and genes of bacterial origin

TL;DR: The presence of bacterial genes in the chloroplast genomes of Bryopsis plumosa and T. expeditiones suggest that these have been acquired through horizontal gene transfer, which may have been facilitated by the occurrence of obligate intracellular bacteria in these siphonous algae.

L1 elements, processed pseudogenes and retrogenes in mammalian genomes.

TL;DR: There is a significant excess ofretrogenes that originate from the X chromosome and are retrotransposed into autosomes, and most of these retrogenes are specially expressed in male germ cells, suggesting the inactivation of X‐linked genes during male meiosis provides a strong selection pressure on retrogenses originating from theX chromosome.

Correlated evolution of genome size and cell volume in diatoms (bacillariophyceae)1

TL;DR: Diatom cell volume is an important component of the global carbon cycle; therefore, understanding the mechanisms that drive diatom genome evolution has both evolutionary and ecological importance.

Genetic and epigenetic changes in rat preneoplastic liver tissue induced by 2-acetylaminofluorene

TL;DR: Exposure of rats to genotoxic hepatocarcinogen 2-AAF, in addition to formation of 1-AAF-specific DNA lesions, resulted in substantial alterations in cellular epigenetic status, which was observed in the liver of male rats only.

Enhanced expression of lmb gene encoding laminin-binding protein in Streptococcus agalactiae strains harboring IS1548 in scpB-lmb intergenic region.

TL;DR: Deletion of the IS1548 sequence between scpB and lmb genes in a CC19 serotype III GBS strain substantially reduced the transcription of lmb gene, the binding ability to laminin, and the expression of Lmb protein, but transcript levels and fibronectin binding ability were similar in the three groups of strains.

hEST2, the Putative Human Telomerase Catalytic Subunit Gene, Is Up-Regulated in Tumor Cells and during Immortalization

TL;DR: The cloning of a human gene, hEST2, that shares significant sequence similarity with the telomerase catalytic subunit genes of lower eukaryotes is reported, suggesting that the induction of hEST 2 mRNA expression is required for the telomersase activation that occurs during cellular immortalization and tumor progression.

HIV-1 Integration in the Human Genome Favors Active Genes and Local Hotspots

TL;DR: Global analysis of cellular transcription indicated that active genes were preferential integration targets, particularly genes that were activated in cells after infection by HIV-1, and this data suggests how selective targeting promotes aggressive HIV replication.
