Sweetpotato Knowledge Portal
Genetic transformation holds considerable promise for sweetpotato enhancement, but is limited by the low regeneration efficiency of transformed cells. Somatic embryogenesis is the most efficient method for regenerating genetically transformed sweetpotato plants, but is still limited by low efficiency and strong genotype dependency. In this study, based on a review …

Genetic transformation is considered as one of the most promising options for improvement of crop traits. Current transformation methods for sweetpotato depend on plant regeneration through organogenesis or somatic embryogenesis. Somatic embryogenesis and plant regeneration at a high frequency has been restricted to a few sweetpotato varieties. Three auxins namely: …

Sweetpotato is cultivated worldwide as a valuable source of food. Weevils cause 60-100% loss of productivity. The present study aims at genetically transforming selected Ugandan sweetpotato cultivars with genes that confer resistance to weevils. A tissue culture method is being optimised to be coupled with Agrobacterium transformation technique for regeneration …
