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.2026/08/06GSE342273GSM9927033GSM9927034GSM9927023GSM9927031GSM9927032GSM9927037GSM9927026GSM9927038GSM9927027GSM9927024GSM9927035GSM9927025GSM9927036GSM9927040GSM9927030GSM9927028GSM9927039GSM992702928300342273Brassica rapa
