Root parasitic weeds are a major constraint to crop production worldwide causing significant yearly losses in yield and economic value. These parasites cause their destruction by attaching to their hosts with a unique organ, the haustorium, that allows them to obtain the nutrients (sugars, amino acids, etc.) needed to complete their lifecycle. | Genome-wide identification of MST SUT and SWEET family sugar transporters in root parasitic angiosperms and analysis of their expression during host parasitism
