项目摘要
Microorganisms, including bacteria, cyanobacteria, microalgae, and various fungi and fungal-like organisms (e.g., Peronsporomycetes), are critical components of all communities today. These organisms certainly performed similar functions in the past, and were responsible for the evolution and sustainability of ancient ecosystems in activities ranging from decomposition to nutrient cycling. Unfortunately, however, relatively little is known about how precisely the individual groups of microorganisms functioned in the geologic past. In this research program, various microorganisms that are three-dimensionally preserved in Early Devonian to Late Carboniferous cherts will be investigated. The Devonian and Carboniferous are important periods of geologic time in which all major lineages of vascular land plants (except angiosperms) and the fundamental architectural principles of their body plan (e.g., roots, shoot axis, leaves) evolved. As a result of this increased plant diversity, the number of ecologically distinct (micro-) habitats increased drastically, which, in turn, has resulted in the evolution of new and specific plant-microbe interactions (e.g., leaf endophytism). Because both microbes and their hosts are preserved in chert, these associations provide an extraordinary opportunity to document the diversity of microbes through an important segment of geologic time, and also to study a number of complex interactions that were critical in the functioning of the ancient terrestrial ecosystems. Some of these interactions include parasitism, saprophytism, and various degrees of mutualistic association. To accomplish the goals of this research agenda an international team was assembled that has expertise with both fossil and extant microbes. The project will encompass four interrelated themes: 1) documenting overall microbe diversity, 2) examining diversity through segments of geologic time in which there are well known host plants, 3) characterizing certain types of mutualistic (mycorrhizal) fungi based on spore wall features used with extant glomeromycoytan fungi, 4) documenting microbe interactions based on host responses. The utilization of structurally preserved organisms is the only method available to directly investigate complex interactions that existed between various microbes and their fossil hosts. Documenting these microorganisms, their associations, and interactions with other organisms will make it possible to trace co-evolutionary trends that can be used together with modern approaches to investigate the evolutionary history of certain types of biological and ecological processes that sustain and drive terrestrial ecosystems.
微生物,包括细菌、蓝藻、微藻和各种真菌和真菌样生物(如Peronsporomycetes),是当今所有群落的重要组成部分。这些生物在过去肯定发挥了类似的功能,并在从分解到营养循环的各种活动中负责古代生态系统的进化和可持续性。然而,不幸的是,在过去的地质时期,人们对单个微生物群的精确功能知之甚少。在本研究项目中,将对早泥盆世至晚石炭世燧石岩中三维保存的各种微生物进行研究。泥盆纪和石炭纪是重要的地质时期,在这两个时期,维管植物(被子植物除外)的所有主要谱系及其身体结构的基本原理(如根、茎轴、叶)都发生了进化。由于植物多样性的增加,生态上独特的(微)栖息地的数量急剧增加,这反过来又导致了新的和特定的植物-微生物相互作用的进化(例如,叶内生作用)。因为微生物和它们的宿主都保存在燧石中,这些关联提供了一个非凡的机会,可以通过一个重要的地质时期记录微生物的多样性,也可以研究一些复杂的相互作用,这些相互作用对古代陆地生态系统的功能至关重要。其中一些相互作用包括寄生、腐生和不同程度的互惠关系。为了完成这一研究议程的目标,一个具有化石和现存微生物专业知识的国际团队被召集起来。该项目将包括四个相互关联的主题:1)记录整体微生物多样性;2)通过已知寄主植物的地质时间片段检查多样性;3)根据现存肾小球菌体真菌的孢子壁特征描述某些类型的共生(菌根)真菌;4)根据寄主反应记录微生物的相互作用。利用结构保存的生物是直接研究各种微生物与其化石宿主之间存在的复杂相互作用的唯一方法。记录这些微生物、它们的关联以及与其他生物的相互作用,将使追踪共同进化趋势成为可能,这些趋势可以与现代方法一起用于调查维持和驱动陆地生态系统的某些类型的生物和生态过程的进化史。
