DISSERTATION EVOLUTION IN THE ABSENCE OF HOMOLOGOUS RECOMBINATION: ECOLOGICAL AND GENETIC MECHANISMS OF ORIGIN AND EXISTENCE 03.00.16 ecology & 03.00.15 genetics Majority of works on evolution have been written for sexual organisms, and thus some important evolutionary conceptions could not be applied to asexual lines directly (for example, conception of species). If we define evolution as a process of accumulation of favorable mutations and elimination of deleterious ones it is necessary to understand the peculiarities of the process in asexual species and non-recombining regions of DNA: what is the mutational rate in asexual lines as compared to sexual, is there effective elimination of deleterious mutations and how frequently do favorable mutations can be combined with each other? Answers on these questions will help us to solve the main evolution puzzle – why does majority of organisms have sexual reproduction? The main goal of the work is to determine specific traits of ancient asexual species and nonrecombinant regions of DNA and to discuss their possible adaptive sense. There three specific tasks: 1. To analyze distribution of deleterious mutations in asexual populations which were originated from sexual populations with various mutational parameters (mutational rate, coefficient of selection against mutations, interaction of mutations with each other); 2. To reveal ecological and genetic traits, specific for ancient asexual species such as rotifera Bdelloidea and freshwater crustacea -Darwinulidae; 3. To reveal specific traits of structure and molecular evolution of Y chromosome of mammals and mitochondrial genome of mammals as examples of non-recombinant genes. In the work I have constructed mathematical model of origin and maintenance of asexual species from sexual ones and consider possible ways of further evolution. I have obtained the first evidences of rather effective elimination of slightly-deleterious mutations in mitochondrial genes as compared to bacterial orthologous. Also, comparing mitochondrial genes of mammals on I have found out the more effective purifying selection in small-bodied species as compared to large-bodied ones. SUMMARY OF KONSTANTIN POPADIN’S WORKS – EVOLUTIONARY GENETICS OF MITOCHONDRIA My main scientific interest is searching of relationships between genetic and ecological traits of vertebrate animals using tools of bioinformatic. Genetic traits of each species (such as rate of accumulation of neutral or slightly deleterious mutations, abundance of nucleotide repeats, Gibbs Energy of transfer RNA’s molecules, physical-chemical traits of proteins) I estimate from complete sequences of mitochondrial genomes. Among ecological – physiological traits I consider body mass, trophic level, generation time, body temperature and basal metabolic rate. For each revealed trend, I suggest evolutionary model with potential functional explanation of the correlation. Investigation of such models helps to understand the basic rules of molecular evolution. The main topic of my work is investigation of evolutionary dynamic of slightly deleterious mutations in mitochondrial genome of vertebrate species and human. Recently, we have analyzed the rate of accumulation of slightly deleterious mutations in mitochondrial genomes of 110 mammalian species. We have revealed that rate of accumulation of these mutations is higher in large-bodied mammals as compared to small-bodied ones. We interpret this correlation in the light of the effectively neutral theory of molecular evolution – the probability of fixation of slightly deleterious mutation due to random genetic drift is higher in populations with low size (i.e. in large-bodied mammals), while majority of slightly deleterious mutations is effectively eliminated in populations with high size (i.e. in small bodied mammals). In other words, the selection is more effective in populations of high size as compared to populations with low size, and body mass is just an approximation of population size of the species (the larger the body size the smaller the population size). The work was published as two separate articles in Proceedings of the National Academy of Science USA (Popadin et al. 2007 PNAS, 104: 13390-5; Nikolaev et al, 2007. PNAS, 104: 2044320448). Additionally we have compared power of purifying selection in mitochondrial and proteobacterial genes and we have revealed, that mitochondria despite the absence of recombination and strong genetic drift due to low effective size possess more effective elimination of slightly deleterious mutations as compared with bacteria (Mamirova et al. 2007. BMC Evol Biol. 7(1):17.). Also we constructed manually curated database of secondary structures of tRNAs from mtDNA of tetrapodes (Popadin et al. 2007, BMC Bioinformatics. 8(1):441), which we plan to use in evolutionary aspects. Since deleterious mutations might determine predisposition of humans to various diseases and even constrain their lifespan, now I investigate dynamic of deleterious mutations in mitochondrial genomes of human populations.
