Zhang H.Y., Chen T., and Zhao L., 2024, Research insight into the genetic regulation of photosynthesis in sweet potato, Genomics and Applied Biology, 15(6): 297-307 (doi: 10.5376/gab.2024.15.0031)

In sweet potato (Ipomoea batatas), improvements in photosynthetic capacity have significant implications for increasing yield, starch production, and resilience under environmental stress. This study explores the genetic regulation of photosynthesis in sweet potato, focusing on key genes, transcription factors, and pathways that enhance photosynthetic efficiency and carbohydrate metabolism. Genes such as IbVP1 and IbMIPS1 play pivotal roles in optimizing photosynthesis, while transcription factors like IbBBX29 and IbC3H18 are critical for stress tolerance and efficient light utilization. Recent advancements in genetic engineering, including CRISPR/Cas9 applications, provide new avenues for precisely modifying photosynthetic traits to boost productivity. Additionally, insights from high-photosynthetic sweet potato varieties and their genetic profiles offer valuable guidance for future breeding programs aimed at achieving higher yield and better adaptability. Understanding the molecular mechanisms behind these genetic factors can facilitate the development of resilient, high-yield sweet potato cultivars, contributing to food security and sustainable agriculture.
