| 1 | In the name of the rose:a roadmap for rose research in the genome era显示文摘The recent completion of the rose genome sequence is not the end of a process,but rather a starting point that opens up a whole set of new and exciting activities.Next to a high-quality genome sequence other genomic tools have also become available for rose,including transcriptomics data,a high-density single-nucleotide polymorphism array and software to perform linkage and quantitative trait locus mapping in polyploids.Rose cultivars are highly heterogeneous and diverse.This vast diversity in cultivated roses can be explained through the genetic potential of the genus,introgressions from wild species into commercial tetraploid germplasm and the inimitable efforts of historical breeders.We can now investigate how this diversity can best be exploited and refined in future breeding work,given the rich molecular toolbox now available to the rose breeding community.This paper presents possible lines of research now that rose has entered the genomics era,and attempts to partially answer the question that arises after the completion of any draft genome sequence:‘Now that we have“the”genome,what’s next?’.Having access to a genome sequence will allow both(fundamental)scientific and(applied)breeding-orientated questions to be addressed.We outline possible approaches for a number of these questions. | Marinus J.M.Smulders Paul Arens Peter M.Bourke Thomas Debener Marcus Linde Jan De Riek Leen Leus Tom Ruttink Sylvie Baudino Laurence Hibrant Saint-Oyant Jeremy Clotault Fabrice Foucher | 2019 | Horticulture Research2019，6，1： | 2 |
| 2 | Diversity and selection of the continuous-flowering gene, RoKSN, in rose显示文摘Blooming seasonality is an important trait in ornamental plants and was selected by humans.Wild roses flower only in spring whereas most cultivated modern roses can flower continuously.This trait is explained by a mutation of a floral repressor gene,RoKSN,a TFL1 homologue.In this work,we studied the origin,the diversity and the selection of the RoKSN gene.We analyzed 270 accessions,including wild and old cultivated Asian and European roses as well as modern roses.By sequencing the RoKSN gene,we proposed that the allele responsible for continuous-flowering,RoKSN copia,originated from Chinese wild roses(Indicae section),with a recent insertion of the copia element.Old cultivated Asian roses with the RoKSN copia allele were introduced in Europe,and the RoKSN copia allele was progressively selected during the 19th and 20th centuries,leading to continuous-flowering modern roses.Furthermore,we detected a new allele,RoKSN A181,leading to a weak reblooming.This allele encodes a functional floral repressor and is responsible for a moderate accumulation of RoKSN transcripts.A transient selection of this RoKSN A181 allele was observed during the 19th century.Our work highlights the selection of different alleles at the RoKSN locus for recurrent blooming in rose. | Vanessa Soufflet-Freslon Emilie Araou Julien Jeauffre Tatiana Thouroude Annie Chastellier Gilles Michel Yuki Mikanagi Koji Kawamura Mark Banfield Cristiana Oghina-Pavie Jeremy Clotault Alix Pernet Fabrice Foucher | 2021 | Horticulture Research2021，8，1： | 1 |
