To characterize transcriptome-wide JA responses in Brassica rapa var. trilocularis, we performed time-course RNA sequencing of mock- and methyl jasmonate (MeJA)-treated R-o-18 seedlings. Leaf tissues were collected at 10 min, 24 h, and 72 h after treatment. MeJA induced rapid and extensive transcriptional reprogramming, including activation of defense-related metabolic pathways and suppression of auxin-responsive, cell-cycle, and stomatal-development genes. MeJA also induced ethylene biosynthesis and signaling genes and coordinately activated transcription factors and biosynthetic genes associated with aliphatic and indolic glucosinolate accumulation. These data provide a transcriptomic resource for understanding jasmonate-mediated growth-defense tradeoffs and chemical defense metabolism in B. rapa.","dates":{"publication":"2026/08/06"},"accession":"GSE342273","cross_references":{"GSM":["GSM9927033","GSM9927034","GSM9927023","GSM9927031","GSM9927032","GSM9927037","GSM9927026","GSM9927038","GSM9927027","GSM9927024","GSM9927035","GSM9927025","GSM9927036","GSM9927040","GSM9927030","GSM9927028","GSM9927039","GSM9927029"],"GPL":["28300"],"GSE":["342273"],"taxon":["Brassica rapa"]}}
