<i>Beta vulgaris</i> ssp. <i>vulgaris</i> chromosome 8 shows significant association with geosmin concentration in table beet

Abstract

AbstractGeosmin, a degraded sesquiterpene molecule with earthy and musty odor, imbues table beet with its characteristic aroma. Geosmin is heritable and endogenously produced in table beet; its earthy aroma is sought by some consumers but deters others. Geosmin biosynthesis is catalyzed by a bifunctional geosmin synthase enzyme in diverse bacteria and fungi, but a mechanism for geosmin biosynthesis in plants has not been reported. This work employed association analysis and selective genotyping of a segregating F2:3Beta vulgarisvulgaris g· kg -1
