Stress information received by a particular local plant tissue is transferred to other tissues and neighboring plants, but how the information travels is not well understood. Application of spores to Arabidopsis leaves or roots stimulates local accumulation of jasmonic acid (JA), the expression of JA-responsive genes, as well as of () and (). Infection information is systemically spread over the entire seedling and propagates radially from infected to non-infected leaves, axially from leaves to roots, and . The local and systemic responses are reduced in the mutant, and the response in the mutant. Information about infection travels slowly to uninfected neighboring plants via a hyphal network, where and are up-regulated. The systemic -induced JA response in infected plants is converted to an abscisic acid (ABA) response in the neighboring plant where ABA and ABA-responsive genes are induced. We propose that the local threat information induced by infection is spread over the entire plant and transferred to neighboring plants via a hyphal network. The JA-specific response is converted to a general ABA-mediated stress response in the neighboring plant.
特定局部植物组织接收到的胁迫信息会传递到其他组织和邻近植物，但信息如何传播尚不清楚。将孢子应用于拟南芥叶片或根部会刺激茉莉酸（JA）的局部积累、JA响应基因的表达，以及（）和（）的表达。感染信息会在整个幼苗中系统性传播，并从受感染叶片向未感染叶片径向传播、从叶片向根部轴向传播，以及（此处原文似乎不完整）。在（）突变体中，局部和系统性反应会减弱，在（）突变体中，（此处原文似乎不完整）反应也会减弱。关于（）感染的信息通过（）菌丝网络缓慢传播到未感染的邻近植物，在那里（）和（）会被上调。受感染植物中系统性（）诱导的JA反应在邻近植物中会转变为脱落酸（ABA）反应，在邻近植物中ABA和ABA响应基因会被诱导。我们提出，由（）感染诱导的局部威胁信息会在整个植物中传播，并通过（）菌丝网络传递到邻近植物。JA特异性反应在邻近植物中会转变为一般的ABA介导的胁迫反应。
