Genome editing to increase resistant starch (RS) in rice is influenced by Waxy (Wx) gene function. Modifying starch biosynthesis genes in specific rice varieties can enhance RS content, but impacts eating quality and yield.
Area of Science:
- Plant Biotechnology
- Nutritional Science
- Agricultural Science
Background:
- Rice endosperm's resistant starch (RS) content is crucial for blood glucose regulation and gut health.
- Genome editing strategies targeting amylopectin biosynthesis show potential for increasing RS.
- The impact of diverse Waxy (Wx) allelic backgrounds on RS accumulation in edited rice remains underexplored.
