GENETIC INVERSIONS. “Inversions are intra-chromosomal rearrangements that do not necessarily result in loss of genetic material. However, inversions can have a considerable impact on meiotic reproduction by reducing recombination frequencies.” https://lnkd.in/eC8eb-V View in LinkedIn

VIRUS REMAINS DRIVE COMPLEXITY. "Eukaryotic complexity appears to be mostly mediated by regulatory complexity involving noncoding retroposon-derived RNA." http://onlinelibrary.wiley.com/doi/10.1111/nyas.12565/full View in LinkedIn

UNEXPECTED BENEFITS. “Loss of genetic material by deletion can reduce the fitness of an organism. However, also the opposite situation can occur, for instance when a pathogen loses genes encoding molecules that are recognized by host immune receptors.” https://lnkd.in/eC8eb-V View in LinkedIn

GROUP IDENTITY. "I proposed that lytic and persisting cryptic virus also provide addiction modules that promote group identity. In eukaryotes (and the RNA world), a distinct RNA virus–host relationship exists. Retrovirurses/retroposons are major contributors to eukaryotic genomes." http://onlinelibrary.wiley.com/doi/10.1111/nyas.12565/full View in LinkedIn

REPURPOSING. “Duplication of genetic material immediately leads to genetic redundancy, whereby gene copies can subsequently diverge and evolve toward novel or altered functionality. In plant pathogenic fungi and oomycetes, the expansion of a plethora of gene families such as peptidases, glycoside hydrolases, kinases, or transporters has been implicated in the pathogenic lifestyle.” https://lnkd.in/eC8eb-V View in LinkedIn

ISLANDS AND PERIPHERY. “Structured genomes contain islands of “core” genes involved in essential functions as well as regions of genes that play a role in adaptation and interaction with the environment. This structure fosters short-term adaptations by increasing the probability of favorable mutations using chromosomal rearrangements.” https://lnkd.in/eC8eb-V View in LinkedIn

WIDESPREAD. “Structured genomes are common in eukaryotes and have been described in plants, animals, and fungi. Structured genomes are also frequently observed in pathogenic organisms.” https://lnkd.in/eC8eb-V View in LinkedIn

STRUCTURED GENOME. “Eukaryotic genomes are not just a random sequence of genes; they are structured and contain clusters of co-expressed genes or genes that operate in the same process, such as the biosynthesis of particular compounds.” https://lnkd.in/eC8eb-V View in LinkedIn

FASTER CHANGE. “A structured genome facilitates genome evolution.” https://lnkd.in/eC8eb-V View in LinkedIn

CONTROLLING ADVERSE EFFECTS. “Transposable elements are powerful facilitators of evolution but may at the same time be harmful to the individual organism. Therefore, several complementary mechanisms to control transposable element activity have evolved. In many fungi, duplicated DNA is actively mutated by a process called repeat-induced point mutation.” https://lnkd.in/eC8eb-V View in LinkedIn
