杀真菌剂托丙威（TPC）是一种黑色素生物合成抑制剂，但它也可能有另一种作用模式。在TPC诱导植物系统获得抗性（SAR）的试验中，TPC诱导了烟草病程相关基因PR-1（拟南芥）和水稻防御相关水杨酸（SA）信号通路中PBZ 1、β-1，3-葡聚糖酶和几丁质酶1基因的启动子活性，但不诱导茉莉酸信号通路基因的启动子活性。丙磺唑（PBZ），一种商业上使用的植物防御激活剂，诱导基因在这两个信号通路。TPC的抗菌活性与PBZ相当。200 μM TPC抑制水稻上的假单胞菌（Pseudomonaseringaepv.maculicolainA.thaliana）生长，30 μM TPC抑制水稻上的黄单胞菌（Xanthomonasoryzaepv. oryzae）生长。本研究的结果表明，TPC功能不仅作为黑色素生物合成抑制剂，而且作为SAR诱导剂，并适用于作为一种新的细菌控制剂，诱导SAR活性在博塔和水稻。
The fungicide tolprocarb (TPC) is a melanin biosynthesis inhibitor, but it may also have another mode of action. Here in tests of TPC for inducing plant systemic acquired resistance (SAR), TPC induced promoter activity of the tobacco pathogenesis-related genePR-1ainArabidopsis thalianaand genes forPBZ1, β-1,3-glucanase, and chitinase 1 in the defense-related salicylic acid (SA) signaling pathway in rice, but not genes for the jasmonate signaling pathway. Probenazole (PBZ), a commercially used plant defense activator, induced genes in both signaling pathways. The antibacterial activity of TPC was equivalent to that of PBZ. Irrigation with 200 μM TPC prevented growth byPseudomonas syringaepv.maculicolainA.thaliana, and 30 μM TPC inhibitedXanthomonas oryzaepv.oryzaegrowth in rice. The results of this study suggest that TPC functions not only as a melanin biosynthesis inhibitor but also as an SAR inducer and is applicable as a novel bacterial control agent that induces SAR activity in bothA.thalianaand rice.
