Long term adaptation to enhanced temperature in Microcystis aeruginosa. Adaptation to enhanced temperature in Microcystis aeruginosa

The three Microcystis aeruginosa strains (M10, M11, M12) used in this study were isolated from Lake Tașaul, Romania (44.35°N 28.61°E) in June 2018. Each strain was adapted to two different temperature conditions, ambient (22°C) and heat-adapted (26°C) for two years. These six M. aeruginosa genomes were then sequenced to determine if adaptation to increased temperature resulted in genetic changes or ‘reversible’ increased plasticity.

本研究所用的3株铜绿微囊藻（Microcystis aeruginosa）菌株M10、M11、M12，于2018年6月从罗马尼亚塔绍尔湖（Lake Tașaul，44.35°N 28.61°E）分离获得。每株菌株均在两种温度条件下完成两年驯化：常温（22℃）与热驯化（26℃）。随后对这6株铜绿微囊藻的基因组进行测序，以明确温度升高驯化是否会引发遗传变化或“可逆性”可塑性提升。
