| Outline of Final Research Achievements |
Based on the whole genome data of the isogamous colonial volvocalean species Gonium pectorale, genetic and genome bases of evolution of mating type locus and initial transition to multicellularity have been revealed. G. pectorale mating type locus and other genome regions lacked homologs of new gender-specific genes of Volvox carteri, suggesting that these genes might have not been acquired by the isogamous ancestors of the colonial Volvocales (Hamaji et al. 2016, G3). The comparative whole genome analyses of undifferentialted multicellular G. pectorale, differentiated multicellular Volvox carteri and unicellular Chlamydomonas reinhardtii demonstrated that cell cycle related genes are importamt for initial transition to multicellularuty (Hanschen et al. 2016, Nat. Comm.).
