Highlights • A de novo onion transcriptome was developed to investigate dormancy transition.• Continuous ethylene induced a climacteric-like respiration peak in stored onions.• Ethylene upregulated ethylene biosynthesis transcripts, ACO1, in onion baseplates.• The ABA biosynthesis gene NCED was upregulated under ethylene supplementation.• tZRP and IPRP are potential markers of onion dormancy status.

与乙烯诱导的洋葱鳞茎休眠相关的转录组和植物激素变化

亮点 • 开发了一个从头洋葱转录组来研究休眠过渡。• 连续乙烯在储存的洋葱中诱导了一个更年期样的呼吸峰。• 乙烯上调了洋葱基板中的乙烯生物合成转录本 ACO1。• ABA 生物合成基因 NCED 在以下条件下上调乙烯补充剂。• tZRP 和IPRP 是洋葱休眠状态的潜在标志。
