Research output: Contribution to conferenceAbstract


Rose is one of the most economically important ornamental crops worldwide. Rosa sp. is well suited genus to become a model for woody ornamentals for a number of reasons: (i) its relative small genome size (500 Mb), (ii) its well documented genetic history with ploïdy events, (iii) its short life for a woody plant, and (iv) availability of different tools, including transcriptomic tools, genetic maps and genetic transformation protocols. Furthermore, the rose represents an original model for studying some ornamental traits that can not be addressed in other model species such as Arabidopsis. Some of these traits, such recurrent blooming, flower morphogenesis or scent production and emission, are of economic interest. The objective of the Rose Genome Sequence Initiative (http://rosegenome.org) is to obtain a high quality rose genome sequence of the diploid R. chinensis ‘Old Blush’. One important issue is the high heterozygosity of roses. To tackle the heterozygosity issue, we propose to develop a high density genetic map to anchor the genome. This genetic map will be developed from a cross between ‘Old Blush’ and R. wichurana. The genotype R. chinensis ‘Old Blush’ will be sequenced using NGS technologies. The data will be assembled and arranged using the high density map. New ESTs will be developed to facilitate assembly and gene annotation. The rose genome sequence will be a great step to help identifying the molecular basis of ornamental traits and also to study genetic diversity and genome evolution in the genus Rosa and in the Rosaceae family.
