摘要:

植物-微生物互惠共生是一种特殊的合作形式, 在整个生命和陆地生态系统的演化历史中起着至关重要的作用。在全球环境变化背景下, 植物和微生物间的互惠共生对生态系统功能的维持具有重要意义。尽管合作/互惠共生如此重要, 在生物学中却存在着对它的历史偏见与忽视。特别地, 尽管互惠共生的理论与建模发展已有较长的历史, 但不同学科分支间仍存在着多种不同的观点。本综述从两个看似对立的视角概述植物-微生物互惠共生的概念框架, 即微生物学家关心的微观机制和生态系统生态学家关注的宏观影响。宏观模型通常从一组过于简单的假设出发, 便于理论分析。但微观机制是开展定量预测的基础, 因此新一代基于过程的宏观模型需嵌入微观机制, 这对预测全球变化下的生态系统响应至关重要。此外, 希望本文也可以吸引更多学者关注合作/互惠的重要作用, 并将这一概念应用于解决其他生态学和社会学问题。

Abstract:

Plant-microbe mutualism, a special form of cooperation, has been crucial throughout the evolutionary history of life and terrestrial ecosystems. With human activities changing the condition of Earth’s surface at an unprecedented rate and scale, we expect this ancient bond between plants and microbes to continue to play a key role. Yet, despite its importance, there has been a historical bias towards cooperation/mutualism in biology, and a general underrepresentation in mathematical biology/theoretical ecology. Moreover, even though theoretical representation of mutualism has come a long way, there exists multiple disparate perspectives with diverse associated scientific communities, among which interaction has been limited. This review focuses on two seemingly opposite schools of perspectives: microbiologists’ perspective that zooms in for the microscale mechanisms vs. ecosystem ecologists’ perspective that zooms out for the macroscale consequences. Macroscale models often start with a simple set of naive assumptions. But over time microscale mechanisms (once understood well) will eventually be incorporated into newer-generation process-based large models, greatly enhancing our ability to quantitatively predict our future. I hope this review can facilitate this process, a process that will only become more important against the backdrop of rapid global change. Lastly, but perhaps more broadly, I hope this review will attract more attention to the important role of cooperation/mutualism, a concept that we can maybe leverage to solve a range of other broader problems in ecology and our society.
