Root and tuber crops, such as potatoes, sweet potatoes, cassava, taro, yams, ginger, konjac, kudzu, pinellia, and others, hold immense significance as important food sources, industrial materials, and medicinal crops. Their yield potential, adaptability, production, and quality are key objectives for breeders worldwide. However, the production of root and tuber crops faces several challenges, including the impacts of biotic and abiotic factors, as well as the need for improved yield and nutritional quality. Currently, molecular genetics and breeding techniques involving biotechnologies such as QTL, GWAS, map-based cloning, omics analysis, and gene or genome editing have made significant strides in model plants. In light of these advancements, we are developing this article collection to address these challenges and present new progress in root and tuber crop research.This Research Topic mainly focuses on analyzing the molecular regulatory mechanisms of quality and resistance in root and tuber crops, which can be explored from physiological, molecular, or multi omics perspectives. The aim is to cultivate new varieties of root and tuber crops with high quality and resistance.We welcome submissions of various article types, including Original Research, Review, Mini Review, Brief Research Report, Perspective, etc., focusing on the following subjects:• Regulation of growth and development, tuberization process, nutrient absorption, metabolism, biotic or abiotic stress responses, and other physiological process of root and tuber crops• Dissection of molecular mechanisms underlying yield or quality traits in root and tuber crops via genetics, omics, or informatics strategies• Yield or quality improvement and molecular breeding of root and tuber crops using genetic and genomic tools
