Par kultivēto saldo kartupeļu genoms satur Agrobacterium T-izraudzītajām valsts iestādēm ar paustajām gēniem: Piemērs dabiski transgēnu pārtikas kultūru

starp 291 pārbaudītas pievienošanās Kultūraugu saldo kartupeļu, visi saturēt vienu vai vairāk transfer DNA (T-DNA) sekvences. Šīs sekvences, which are shown to be expressed in a cultivated sweet potato clone (“Huachano”) that was analyzed in detail, suggest that an Agrobacterium infection occurred in evolutionary times. One of the T-DNAs is apparently present in all cultivated sweet potato clones, but not in the crop’s closely related wild relatives, suggesting the T-DNA provided a trait or traits that were selected for during domestication. This finding draws attention to the importance of plant–microbe interactions, and given that this crop has been eaten for millennia, it may change the paradigm governing the “unnatural” status of transgenic crops.
