Research Project: Molecular Approaches: Identifying Regulatory Mechanisms Controlling Plant Growth, Development and Survival and the role of the microbiome

Location: Plant Gene Expression Center

Project Number: 2030-21000-051-03-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Aug 1, 2017
End Date: Jul 31, 2022

Objective:
Determine the molecular mechanisms by which plants perceive and respond to developmental, biotic and abiotic signals throughout the life cycle to enhance the quality and production efficiency of agriculturally important crops.

Approach:
A combination of molecular, genetic, genomic, and bioinformatic approaches will be used to address this multifaceted problem. Particular emphasis will be placed on identifying signaling components, regulatory genes and transcriptional networks involved in controlling plant responses to developmental, biotic and abiotic signals. Genes that respond to light under control of the phytochrome photosensory system will be identified and the regulatory mechanisms defined. Genes involved in regulating the circadian clock will be identified and functionally defined. Genes controlling vegetative and reproductive development will be identified and characterized. Plant hormone function in mediating growth and developmental responses will be explored. Genes involved in plant responses to biotic and abiotic challenges will be identified and characterized. The impact of the microbiome on plant genotypes and farming practices will be determined. On an ongoing basis, cutting-edge strategies and technologies such as next generation sequencing and computational modeling, will be assimilated and developed.
