Defining the chemical environment and molecular signals that influence community structure and function
Understanding how the local environment in the rhizosphere influences and is influenced by community composition and function represents a key knowledge gap and is the focus of Objective 2.
Objective 2 Tasks
- Task 2.1 – Identify the spatial and temporal characteristics of host derived signals and determine their roles in community establishment and organization.
- In this task, we will develop and refine strategies for sampling the local chemical environment around the host plant.
- Task 2.2 – Understand the exchangeable chemical signals that influence bacterial community organization.
- the goal of this task is to characterize the mechanism by which the PipR system mediates bacterial association with plants.
- Task 2.3 – Understand the exchangeable chemical signals that influence fungal community organization.
- We will focus on understanding the mechanisms used by fungi to communicate with each other, and with the host plant, to promote plant association and community development.
