The Rosaceae family has striking phenotypic diversity and high syntenic *** trifoliata is sister species to the Maleae tribe of apple and~1000 other *** has many putative ancestral features,such as herb/sub-shrub habit,dry fruit-bearing and nine base *** coalescence of ancestral characters in a phylogenetically important species,positions Gillenia as a‘rosetta stone'for translational science within *** present genomic and phenological resources to facilitate the use of Gillenia for this *** Gillenia genome is the fi rst fully annotated chromosome-level assembly with an ancestral genome complement(x=9),and with it we developed an improved model of the Rosaceae ancestral *** and NAC gene family analyses revealed genome dynamics correlated with growth and reproduction and we demonstrate how Gillenia can be a negative control for studying fl eshy fruit development in Rosaceae.
