Abstract：
This study reveals a new acclimation mechanism of the eukaryotic unicellular green alga Chlorella vulgaris in terms of the effect of varying atmospheric pressures on the structure and function of its photosynthetic apparatus using fluorescence induction measurements (JIP-test). The results indicate that low (400mbar) and extreme low (2 atmosphere (simulating the Mars atmosphere), reveals that the impact of extremely low atmospheric pressure on PQ mobility within the photosynthetic membrane, coupled with the low density of an almost 100% CO2 Mars-like atmosphere, results to a similar photosynthetic efficiency to that on Earth. These findings pave the way for the identification of novel functional acclimation mechanisms of microalgae to extreme environments that are vastly distinct from those found on Earth.
摘要：
这项研究揭示了真核单细胞绿藻小球藻的一种新的适应机制，该机制是通过使用荧光诱导测量（JIP测试）来研究大气压力变化对其光合装置的结构和功能的影响。结果表明，低（400mbar）和极低（2个大气（模拟火星大气），揭示了极低气压对光合膜内PQ迁移率的影响，再加上几乎100%二氧化碳类似火星的大气层的低密度，结果与地球上的光合效率相似。这些发现为鉴定微藻对极端环境的新型功能适应机制铺平了道路，这些机制与地球上发现的机制截然不同。
