| Outline of Final Research Achievements |
We found that two major quantitative loci (QTLs) relating prickle density of rose using the F1 population of “The Fairy” × RW (a hybrid of R. wichrana). From the strawberry genome information, ATHB-15, WRKY-44, RoPHAN and RoKN1 genes co-localised with the QTLs were identified as candidate genes for prickle formation on rose. Within the genes, RoKN1 seemed to suppress the prickle formation from the results of different expression patterns between R. multiflora and its prickleless mutant, and clarified that the number of prickles reduced significantly at F1 materials showing RoKN1-1/1-1 genotype. We have succeeded in VIGS of rose by using ALSV vector, however, did not reach to produce a manifested RoKN1 restraint individual.
