Integrated metabolomics and transcriptomics analysis reveals the potential mechanism by which Methyl jasmonate enhances the pungent flavor of soilless-cultivated Chinese chives (Allium tuberosum).

ABSTRACT:

Background

Methyl jasmonate (MeJA) is an effective plant elicitor that enhances secondary metabolism. Chinese chives are prized for their pungent flavor, yet the biosynthetic pathways and regulatory mechanisms of flavor compounds induced by MeJA remain unclear.

Methodology

This study integrated metabolomic and transcriptomic analyses to elucidate how MeJA modulates the biosynthesis of flavor substance precursors in soilless-cultivated Chinese chives.

Results

MeJA treatment improved the dry matter content and nutritional quality of Chinese chives. We identified 36 volatile and 183 nonvolatile differentially abundant metabolites between the MeJA-treated and control groups. Gene expression analysis revealed 193 candidate genes associated with flavor formation. Among all
