■Outline
The course will introduce topics on modern evolutionary biology including the fundamentals of the methods for comparative genomics analyses. The first topic is the methodogy for evolutionary analysis, which will cover genome sequencing, orthology analysis, genome comparison and detection of selection signature. Subsequently, we will explore the evolutionary mechanism that brings about the diversity of organisms. For instance, turnovers of sex determination genes have frequently happened during the evolution of vertebrates. Genetic and genomic basis of this phenomenon will be discussed using fish as models. Arbuscular mycorrhiza and root nodule symbioses are mutually successful and beneficial interactions on earth. The evolution of plant-microbe symbioses by recruiting or neo-functionalizing common factors will be discussed. The evolutionary novelties acquired by insects through evolution will be discussed.
■Learning objectives
1.Learn the principles of genome sequencing and acquire a fundamental understanding of the bioinformatics techniques utilized in genome analysis and molecular evolution study.
2.Understand the basic concepts, methods, and applications of comparative genomics.
3.Understand the diversity and evolution of sex-determination systems in fish. 4.Understand the evolution of symbiotic mechanisms between legumes and nitrogen-fixing bacteria.
5.Understand the molecular mechanisms and evolution of arbuscular mycorrhizal symbiosis.
6.Understand the diversity and evolution of insects.
■Grading policy
Grades are determined based on class attendance and the quality of papers submitted to the lecturer by the deadline. The subject of the paper must be one of the six course objectives.
