Life is a dynamic process driven by the complex interplay between physical constraints and selection pressures, ranging from nutrient limitation to inhibitory substances to predators. These stressors are not mutually exclusive; microbes have faced concurrent challenges for eons. Genome-enabled systems biology approaches are adapting economic and ecological concepts like tradeoff curves and strategic resource allocation theory to analyze metabolic adaptations to simultaneous stressors. These methodologies can accurately describe and predict metabolic adaptations to concurrent stresses by considering the tradeoff between investment of limiting resources into enzymatic machinery and the resulting cellular function. The approaches represent promising links between computational biology and well-established economic and ecological methodologies for analyzing the interplay between physical constraints and microbial fitness.
生命是一个由物理约束和选择压力之间复杂相互作用驱动的动态过程,这些压力源包括营养限制、抑制物质和捕食者等。这些压力源不是相互排斥的;微生物已经面临了亿万年的并发挑战。基因组驱动的系统生物学方法正在适应经济和生态概念,如权衡曲线和战略资源分配理论,以分析代谢对同时存在的压力源的适应。这些方法可以通过考虑限制资源投入到酶机制和由此产生的细胞功能之间的权衡,准确地描述和预测代谢对并发压力的适应。这些方法代表了计算生物学与经济和生态方法之间有前途的联系,可用于分析物理约束和微生物适应性之间的相互作用。
