Review on the glutinous physiological quality and SS genes polymorphism of Indian pumpkin germplasm resources / Xuetao Wu and Yufei Yan

Indian pumpkin, as one of the major cultivars of annual trailing herbaceous plants of the genus Pumpkin in the family Cucurbitaceae, is native to South America and widely grown in China, especially in Zhejiang Province, which is an important garden crop and food crop in China. Starch is an important component of pumpkin pulp and an important basis for the glutinous quality of pumpkin germplasm resources, and its synthesis is mainly determined by the SS (Starch synthases) gene in pumpkin. This review takes Indian pumpkin as an example to summarize the current progress of research on starch and explore its biosynthesis and regulatory processes, including the analysis of the physicochemical properties of the SS gene and the construction and analysis of the evolutionary tree, etc. Meanwhile, with the development of molecular marker technology, it has become possible to utilize bioinformatics tools to analyze the sequence and predict the physicochemical properties of the SS gene family members in Indian pumpkin, and the use of related technologies will promote pumpkinrelated results into life use.
