Outline of Final Research Achievements

The pear fruits usually show green or yellow skin, but some cultivars show red skin caused by bud mutation.In this study, we found that these red skin color was caused by accumulation of the anthocyanin and it required sunlight. Also, solid type and brush type was present in red skin cultivars, but it was suggested that each red skin cultivar has inherited accumulation pattern except for coloration type. Gene expression analysis and DNA blot analysis of genes correlated with anthocyanin accumulation showed large size deletion or insertion did not exist in coding region of those genes, suggesting exist of SNPs or deletion/insertion in non-coding region.
