项目摘要
Soil microorganisms play a crucial role for the functioning of forest ecosystems by influencing uptake and cycling of nutrients and shaping plant diversity and productivity. In the last decade knowledge on microbial diversity and community structure in soils has been triggered dramatically by advances in sequencing technologies. This opens new avenues to address microbial ecological questions in large and multidisciplinary projects. In the previous phases of the Research Unit BEF-China we used high-throughput pyrotag sequencing to analyse soil microbial communities both in the Comparative Study Plots (CSPs) and in the Main Experiment at both Sites A and B. We found a strong relationship between forest age, plant community and soil microbial community in the CSPs. Results from the Main Experiment indicated clear effects of both tree species identity and tree richness on the soil fungal community already at this early stage of tree seedling establishment. Further shifts in the microbial community composition are to be expected with ongoing growth of the plants. For forest ecosystems it is known that the major part of the primary production is transferred to the soils either as root exudates or as dead organic matter. This defines the rhizosphere and coarse wood debris as two hot spots of plant influence on soil microbial communities in forests. These hot spots are only weakly explored, but can be expected to be of major importance especially in the highly diverse subtropical forests.In the 3rd phase of the BEF-China research unit SP7 will focus on understanding the functional relationships between plant biodiversity and below ground microbial diversity in subtropical forest ecosystems. Both the rhizosphere and coarse wood debris (CWD) will be investigated as the two key soil compartments where cycling and acquisition of nutrients are controlled. Our two objectives are: (1) To analyse changes in the diversity and community composition of the rhizosphere soil microbiomes of single tree species along increasing plant species richness gradients within the BEF-China Main Experiment. (2) To study the impact of tree species identity, wood trait, decay rate, canopy gap and plant diversity levels on the microbial communities decomposing (CWD), using the multi-functionality multi-diversity array (MMA) designed by SP10. We will employ both targeted fungal ITS rDNA pyrotag and prokaryotic 16S rDNA illumina paired end sequencing approaches. Addressing this broad array of the soil microbial communities will enable us to analyse the patterns of cooccurrence and interaction networks of specific functional groups of microbes and the tree species in order to obtain a mechanistic understanding of the plant-microbe interactions in the rhizosphere and CWD hot spots. The results will improve our understanding of the role of the plant microbiome in maintaining plant diversity and productivity in forest ecosystems.
土壤微生物通过影响养分的吸收和循环以及形成植物多样性和生产力,对森林生态系统的功能发挥着至关重要的作用。在过去的十年中,测序技术的进步极大地促进了对土壤中微生物多样性和群落结构的了解。这为解决大型多学科项目中的微生物生态问题开辟了新的途径。在BEF-China研究单位的前几个阶段,我们使用高通量pyrotag测序分析了比较研究地块(CSP)和A和B场地主实验中的土壤微生物群落。我们发现,森林年龄,植物群落和土壤微生物群落的CSP之间有很强的关系。从主要实验的结果表明,明确的影响,树种的身份和树木丰富的土壤真菌群落已经在这个早期阶段的树苗建立。随着植物的不断生长,预计微生物群落组成将进一步变化。就森林生态系统而言,人们知道,初级生产的大部分以根系分泌物或死亡有机物的形式转移到土壤中。这表明根际和粗木屑是植物对森林土壤微生物群落影响的两个热点。这些热点只是微弱的探索,但可以预期是非常重要的,特别是在高度多样性的亚热带森林。在BEF-中国研究单位SP 7的第三阶段将集中在了解亚热带森林生态系统中植物多样性和地下微生物多样性之间的功能关系。根际和粗木残体(CWD)将作为两个关键的土壤分区进行调查,其中循环和获取的养分控制。我们的两个目标是:(1)分析BEF-China主试验内单树种根际土壤微生物群落的多样性和群落组成随植物物种丰富度沿着递增梯度的变化。(2)利用SP10设计的多功能多样性阵列(MMA),研究树种特性、木材性状、腐朽率、林窗和植物多样性水平对微生物群落分解(CWD)的影响。我们将采用靶向真菌ITS rDNA pyrotag和原核16 S rDNA illumina配对末端测序方法。解决这个广泛的土壤微生物群落将使我们能够分析的共生模式和特定功能群的微生物和树种的相互作用网络,以获得一个机械的理解植物微生物的相互作用在根际和CWD热点。这些结果将提高我们对植物微生物组在维持森林生态系统植物多样性和生产力方面的作用的理解。
