Plant & Mycorrhizal Fungi Networks By Andy Singh

Overview Introduction Problem & Challenges Background Solution Conclusion Questions

Introduction

Introduction Symbiotic relationship between Plants and Mycorrhizal Fungi Plants give carbon derived form photosynthesis Mycorrhizal Fungi share valuable nutrients

Introduction

Introduction

Problem Why should we care? Agriculture: We are running out of phosphorus. Plant and Mycorrhizal Fungi networks is a simple solution.

Problem How do you achieve optimal symbiosis? How do you to detect communities within the network? What are the driving factors for community development?

Challenges It is time consuming and expensive to sample DNA of plants and fungi It is hard to determine what is a community It is hard to say what exactly facilitates growth of communities

Background Community level network analysis missing Trait-based partner selection Host identity a driving factor Functional diversity in agricultural systems

Solution What is the best way to discover communities? Use predictive analysis for community detection Community detection vs. Clustering

Conclusion Foundation of project Problem & challenges Background studies My approach
