How drought and ploidy level shape gene expression and DNA methylation in Phragmites australis.

ABSTRACT:

Key message

Key drought-response genes regulate saccharopine, mevalonate, water-stress pathways, and cell wall remodeling. Ploidy level influences gene expression under drought and non-stress conditions. Octoploids overall exhibit lower methylation than tetraploids. Drought stress significantly affects plant physiology and growth, yet the molecular mechanisms underlying drought responses remain poorly understood. In this study, we investigate how tetraploid and octoploid Phragmites australis (common reed), a key species in wetland ecosystems and paludiculture, respond to drought at the transcriptional and epigenetic levels. Using RNA-seq, we identify changes in gene expression after 20 and 30 days of drought and assess methylation-sensitive amplification polymorphism (MSAP) over 50
