摘要
Size is one of the most important 生物 traits influencing organismal 生態學 and 演化. However, we know little about the drivers of body size 演化 in unicellulars. A long-term 演化 experiment (Lenski's LTEE) in which Escherichia coli adapts to a simple glucose medium has shown that not only the growth rate and the fitness of the bacterium increase over time but also its cell size. This increase in size contradicts prominent 'external 擴散' theory (EDC) predicting that cell size should have evolved toward smaller cells. Among several scenarios, we propose and test an alternative 'internal 擴散-constraint' (IDC) hypothesis for cell size 演化. A change in cell volume affects metabolite concentrations in the cytoplasm. The IDC states that a higher 代謝 can be achieved by a reduction in the molecular traffic time
