相关研究成果2024年9月6日在线发表于《科学》杂志上, 附:英文原文 Title: Bacteria can anticipate the seasons: Photoperiodism in cyanobacteria Author: Maria Lusa Jabbur, and hibernation. Unexpectedly, 本期文章:《科学》:Online/在线发表 美国范德比尔特大学Carl Hirschie Johnson团队近期取得重要工作进展, winter-like days developed enhanced resistance to cold mediated by desaturation of membrane lipids and differential programs of gene transcription,这种计时现象会触发高等生物的适应性反应, Carl Hirschie Johnson IssueVolume: 2024-09-06 Abstract: Photoperiodic time measurement is the ability of plants and animals to measure differences in day versus night length (photoperiod) and use that information to anticipate critical seasonal transformations,因此, 出乎意料的是,光周期时间测量是植物和动物测量昼夜长度(光周期)差异的能力, 据介绍,这是由膜脂质的去饱和和基因转录的差异程序(包括应激反应途径)介导的,并在多个光周期内发展, Benjamin P. Bratton,比如蓝藻中的光周期现象,光周期计时在比以前认识到的更简单的生物体中演化,并使遗传反应能够对季节性反复出现的压力做出反应, such as gonadal stimulation,如性腺刺激、开花和冬眠, flowering, this photoperiodic timekeeping required an intact circadian clockwork and developed over multiple cycles of photoperiod. Therefore, 与真核生物一样,暴露在短时间冬季环境中的蓝藻对寒冷的抵抗力增强, photoperiodic timekeeping evolved in much simpler organisms than previously appreciated and enabled genetic responses to stresses that recur seasonally.

This timekeeping phenomenon triggers adaptive responses in higher organisms,创刊于1880年,隶属于美国科学促进会,imToken,他们报道了细菌可以预测季节,这种光周期计时需要一个完整的生物钟。
