大豆胞囊线虫(Heterodera glycines Ichnohe,soy-bean cyst nematode,SCN)病是大豆生产中的毁灭性病害,处于休眠期的SCN对不良环境条件具有较高适应性,能适应冬季低温,给防治工作造成较大困难,因此对休眠期SCN代谢机制的研究具有重要意义。线虫卵的主要成分是碳水化合物、蛋白质和脂类,其中海藻糖是一种抗冻剂,有助于线虫抵抗干 Heterodera glycines Ichnohe (soy-bean cyst nematode, SCN) is a devastating disease in soybean production. During dormancy, SCN has high adaptability to adverse environmental conditions and can adapt to low temperature in winter, Resulting in greater difficulties, so the study of SCN metabolism during dormancy is of great significance. The main components of nematode eggs are carbohydrates, proteins and lipids, of which trehalose is a cryoprotectant that helps nematodes resist dry
