Transcriptome and Metabolome Analysis Revealing the Improved ε-Poly- l -Lysine Production Induced by a Microbial Call from Botrytis cinerea

Abstract

This work identified the role of microbial elicitors on ε-PL production and disclosed the underlying mechanism through analysis of gene transcription, key enzyme activities, and intracellular metabolite pools, including transcriptome and metabolome analysis. It was the first report for the inducing effects of the “microbial call” to Streptomyces albulus and ε-PL biosynthesis, and these elicitors could be potentially obtained from decayed fruits infected by Botrytis cinerea ; hence, this may be a way of turning a biohazard into bioproduct wealth.
