Steroidal glycoalkaloids (SGAs), predominantly comprising α-solanine (CHNO) and α-chaconine (CHNO), function as natural phytotoxins within potatoes. In addition to their other roles, these SGAs are crucial for enabling potato plants to withstand biotic stresses. However, they also exhibit toxicity towards humans and animals. Consequently, the content and distribution of SGAs are crucial traits for the genetic improvement of potatoes. This review focuses on advancing research related to the biochemical properties, biosynthesis, regulatory mechanisms, and genetic improvement of potato SGAs. Furthermore, we provide perspectives on future research directions to further enhance our understanding of SGA biosynthesis and regulation, ultimately facilitating the targeted development of superior potato varieties.
甾体糖苷生物碱（SGAs）主要由α-茄碱（C₂₇H₄₃NO₁₅）和α-查茄碱（C₂₇H₄₁NO₁₅）组成，在马铃薯中作为天然植物毒素发挥作用。除了其他作用外，这些SGAs对于使马铃薯植株能够抵御生物胁迫至关重要。然而，它们对人和动物也具有毒性。因此，SGAs的含量和分布是马铃薯遗传改良的关键性状。本综述着重推进与马铃薯SGAs的生化特性、生物合成、调控机制及遗传改良相关的研究。此外，我们还对未来的研究方向提出了展望，以进一步加深我们对SGA生物合成和调控的理解，最终推动优质马铃薯品种的定向培育。
