Adaptive evolution after gene duplication.

Austin L Hughes
View original source ↗Export metadata ↓

Abstract

One of the two ribonuclease genes in a leaf-eating monkey has adapted to a role in the digestion of bacterial RNA. Following duplication of the ancestral ribonuclease gene, adaptation occurred through a series of changes in the amino acid sequence of the protein it encodes. This example is a good illustration of how specialization of protein function after gene duplication can be as source of novel protein functions.

Evolutionary genomics of Culex pipiens: global and local adaptations associated with climate, life-history traits and anthropogenic factors.

We present the first genome-wide study of recent evolution in Culex pipiens species complex focusing on the genomic extent, functional targets and likely causes of global and local adaptations. We resequenced pooled samples of six populations of C. pipiens and two populations of the outgroup Culex torrentium. We used principal component analysis to systematically study differential natural selection across populations and developed a phylogenetic scanning method to analyse admixture without haplotype data. We found evidence for the prominent role of geographical distribution in shaping population structure and specifying patterns of genomic selection. Multiple adaptive events, involving genes implicated with autogeny, diapause and insecticide resistance were limited to specific populations. We estimate that about 5-20% of the genes (including several histone genes) and almost half of the annotated pathways were undergoing selective sweeps in each population. The high occurrence of sweeps in non-genic regions and in chromatin remodelling genes indicated the adaptive importance of gene expression changes. We hypothesize that global adaptive processes in the C. pipiens complex are potentially associated with South to North range expansion, requiring adjustments in chromatin conformation. Strong local signature of adaptation and emergence of hybrid bridge vectors necessitate genomic assessment of populations before specifying control agents.

Adaptive evolution drives divergence of a hybrid inviability gene between two species of Drosophila.

Speciation--the splitting of one species into two--occurs by the evolution of any of several forms of reproductive isolation between taxa, including the intrinsic sterility and inviability of hybrids. Abundant evidence shows that these hybrid fitness problems are caused by incompatible interactions between loci: new alleles that become established in one species are sometimes functionally incompatible with alleles at interacting loci from another species. However, almost nothing is known about the genes involved in such hybrid incompatibilities or the evolutionary forces that drive their divergence. Here we identify a gene that causes epistatic inviability in hybrids between two fruitfly species, Drosophila melanogaster and D. simulans. Our population genetic analysis reveals that this gene--which encodes a nuclear pore protein--evolved by positive natural selection in both species' lineages. These results show that a lethal hybrid incompatibility has evolved as a by-product of adaptive protein evolution.

Malaria parasites and red blood cells: from anaemia to transmission.

Malaria parasites, Plasmodium spp., invade and exploit red blood cells during their asexual expansion within the vertebrate host. The parasite has evolved a suite of adaptive mechanisms enabling optimal exploitation of the host blood cell environment, avoiding host destruction, maintaining a parasite reservoir of infection and producing sexual transmission stages to infect mosquitoes. The highly variable nature of the host blood environment, both over the course of an infection and as a result of other parasitic infections, has selected for the evolution of considerable phenotypic plasticity in the parasite's response to its environment, particularly those phenotypes concerning transmission of the parasite to mosquitoes. With the evolution of human society, human malaria disease is becoming an increasingly urban problem. This imposes different selection pressures on the parasite. The extent to which the parasite is truly plastic over the short term rather than adaptive over the long term will determine the urban epidemiology of malaria and is essential for developing appropriate control methods. Understanding the adaptive nature of malaria parasites is thus vital for anticipating the future visage of urban human malaria.
