昆虫可以“暂停”生命？我科学家破解其中奥秘

Core Insights - The research led by Professor Wang Yaohui's team from Anhui Agricultural University and researcher Zhan Shuai from the Chinese Academy of Sciences has identified a biological clock gene named Cycle that plays a crucial role in regulating insect diapause, revealing the molecular mechanisms behind this phenomenon [1][2]. Group 1: Research Findings - Insects have evolved a survival strategy known as diapause, allowing them to pause their life cycle in response to harsh environmental conditions such as food shortages and extreme temperatures [1]. - The study focused on the silkworm and corn borer, utilizing genomic data analysis and genome editing to uncover the genetic regulation of diapause [1]. - The Cycle gene can produce three different variants (A, B, and C subtypes) through alternative splicing, with A and B subtypes regulating circadian rhythms, while the C subtype is responsible for triggering diapause in response to low temperatures or short daylight signals [1]. Group 2: Implications - This research represents a significant breakthrough in understanding seasonal adaptation in insects, providing new theories on how life interacts with the environment [2]. - The findings have important implications for understanding pest population dynamics, ensuring food security, and promoting ecosystem stability [2].
