Abstract

In the long history of human relations with flowering cherry trees in Japan, 'Somei-Yoshino' occupies an exceptional position among a variety of flowering trees: it is a self-incompatible interspecific hybrid but has been enthusiastically planted by grafting throughout Japan, due most likely to its flamboyant appearance upon full bloom. Thus, 'Somei-Yoshino' gives us a rare opportunity to trace and investigate the occurrence and distribution of somatic mutations within a single plant species through analysis of the genomes of the clonally propagated trees grown under a variety of geographical and artificial environments. In the studies presented here, a total of 46 samples of 'Somei-Yoshino' trees were collected and their genomes were analysed. We identified 684 single nucleotide mutations, of which 71 were present in more than two samples. Clustering analysis of the mutations indicated that the 46 samples were classified into eight groups, four of which included 36 of the 46 samples analysed. Interestingly, all the four tree samples collected in Ueno Park of Tokyo were members of the four groups mentioned above. Based on comparative analysis of their mutations, one of the four trees growing in Ueno Park was concluded to be the closest to the original ancestor. We propose that somatic mutations may be used as tracers to establish the ancestral relationship amongst clonally propagated individuals. [ABSTRACT FROM AUTHOR]
