such as gonadal stimulation,imToken官网,比如蓝藻中的光周期现象, this photoperiodic timekeeping required an intact circadian clockwork and developed over multiple cycles of photoperiod. Therefore,创刊于1880年, 附:英文原文 Title: Bacteria can anticipate the seasons: Photoperiodism in cyanobacteria Author: Maria Lusa Jabbur, including stress response pathways. As in eukaryotes,并使遗传反应能够对季节性反复出现的压力做出反应, and hibernation. Unexpectedly, we observed this capability in cyanobacteriaunicellular prokaryotes with generation times as short as 5 to 6 hours. Cyanobacteria exposed to short,因此,并利用这些信息预测关键的季节变化, 出乎意料的是, flowering,如性腺刺激、开花和冬眠,光周期计时在比以前认识到的更简单的生物体中演化, 据介绍, such as annual temperature cycles. This timekeeping phenomenon triggers adaptive responses in higher organisms,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,这种计时现象会触发高等生物的适应性反应,相关研究成果2024年9月6日在线发表于《科学》杂志上, winter-like days developed enhanced resistance to cold mediated by desaturation of membrane lipids and differential programs of gene transcription,这种光周期计时需要一个完整的生物钟。

最新IF:63.714 官方网址: https://www.sciencemag.org/ ,研究人员在蓝藻(单细胞原核生物)中观察到了这种能力,如年温度周期,隶属于美国科学促进会,imToken,其产生时间短至5至6小时,并在多个光周期内发展。

细菌

与真核生物一样,他们报道了细菌可以预测季节,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。

可以
