In response to trehalose treatment in roots, defense-related transcription factors, WRKY10 and WRKY45, were induced immediately in root and then in shoot after 6-12 h. Pathogenesis-related (PR) proteins are also found to be induced in root at 2-4 h after the treatment and 12-48 h in shoot. Trehalose-induced immediate JA and JA-Ile accumulation, suggesting JA-related compounds can be a signaling molecule that delivers the signal from root to shoot.

根中海藻糖处理后，防御相关转录因子WRKY10和WRKY45在根中立即被诱导，并在处理后2-4h和12-48h在根中被诱导。海藻糖诱导的JA和JA-Ile的即刻积累，表明JA相关化合物可能是一种信号分子，将信号从根传递到地上部。
