中文摘要

海藻糖处理根后，根和地上部分别诱导表达了防御相关转录因子WRKY 10和WRKY 45。在根和地上部中，分别在处理后2-4 h和12-48 h诱导产生了病原相关蛋白（PR）。海藻糖诱导JA和JA-Ile的立即积累，表明JA相关化合物可以是将信号从根传递到芽的信号分子。
英文摘要
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.
