摘要

1.The mutation breeding of plants In 2016,the mutation mechanism of various plant mutants including Arabidopsis thaliana,Geranium,Trades-cantia uminensis,Taraxacum koksaghyz Rodin and algae obtained by heavy ion beam mutation breeding techniques were investigated.The genome-wide profiling of an Arabidopsis mutant named civar(Carbon ion beams Induced Variegated)was revealed by using re-sequencing and the rough map-based cloning techniques.A phenotype screening of Arabidopsis thaliana irradiated by carbon ion beams based on high-throughput imaging technique combining the principal component analysis and scatter matrix clustering analysis was built and optimized which can screen the variation of plant mutant populations.The pigment components and quantities and expression profiles of key genes involved in anthocyanin biosynthesis of flower-color mutant of Geranium and leaf-color mutant of Trades-cantia uminensis were investigated.Mutation breeding of Taraxacum koksaghyz Rodin induced by carbon ion beam irradiations which is notable for its production of high quality rubber and inulin was started.In addition,the photosynthetic response of the mutants of Scenedesmus quadricauda with altered pigment features were analyzed.
