Induction of somatic embryogenesis in recalcitrant sweetpotato (Ipomoea batatas L.) cultivars

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: …

Efficient regeneration and transformation systems for improving resistance to weevils in Ugandan sweetpotato cultivars

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 …
