Abstract / Bemerkung
Most crop plants, including sugar beet (Beta vulgaris subsp. vulgaris), suffer from domestication bottlenecks and low genetic diversity caused by extensive selection for few traits. However, crop wild relatives (CWRs) harbour useful traits relevant for crop improvement, including enhanced adaptation to biotic and abiotic stresses. Especially polyploids are interesting from an evolutionary perspective as genes undergo reorganisation after the polyploidisation event. Through neo- and subfunctionalisation, novel functions emerge, which enable plants to cope with changing environments and extreme/harsh conditions. Particularly in the face of climate change, specific stress and pathogen resistances or tolerances gain importance. To introduce such traits into breeding material, CWRs have already been identified as an important source for sustainable breeding. The identification of genes underlying traits of interest is crucial for crop improvement. For beets, the section Corollinae contains the tetraploid species Beta corolliflora (2n=4x=36) that harbours salt and frost tolerances as well as a wealth of pathogen resistances. The number of beneficial traits of B. corolliflora is increased compared to those of the known diploids in this section (all 2n=2x=18). Nevertheless, neither the parental relationships of B. corolliflora have been resolved, nor are genomic resources available to steer sustainable, genomics-informed breeding. To benefit from the resources offered by polyploid beet wild relatives, we generated a comprehensive pangenome dataset including B. corolliflora, Beta lomatogona, and Beta macrorhiza, as well as a more distant wild beet Patellifolia procumbens (2n=2x=18). Joined analyses with publicly available genome sequences of two additional wild beets allowed the identification of genomic regions absent from cultivated beet, providing a sequence database harbouring traits relevant for future breeding endeavours. In addition, we present strong evidence for the parental relationship of the B. corolliflora wild beet as an autotetraploid emerging from B. macrorhiza.
