Location: Horticultural Crops Research

Project Number: 2072-12220-004-14-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Sep 1, 2011
End Date: Feb 1, 2016

1. Determine the influence of phloroglucinol and other metabolites of Pf-5 on the transcriptome and antibiotic-production profiles of the bacterium 2. Evaluate the role of phloroglucinol in cell-to-cell communication between strains of P. fluorescens.

Global patterns of gene expression by P. fluorescens will be assessed using RNA-Seq, and statistical methods employed to identify genes whose expression is altered by exogenous sources of phloroglucinol or other metabolites. Metabolic profiles will be generated by HPLC analysis of extracts from cultures of P. fluorescens.
