已知丛枝菌根真菌（AMF）和哈茨木霉（Trichoderma harzianum）通过与植物激素的合成或运输相互作用而影响植物生长和抗病性。这些微生物与其宿主植物之间的串扰通常发生在自然界中，并可能影响植物的抗性。同时定量的甜瓜植株的芽揭示了显着的变化，响应于接种T。harzianum和两种不同的AMF（Glomus intraradices和Glomus mosseae）。对甜瓜地上部玉米素（Ze）、吲哚乙酸（IAA）、1-氨基环丙烷-1-羧酸（ACC）、水杨酸（SA）、茉莉酸（JA）和脱落酸（阿坝）的分析表明，甜瓜对G. intraradices和G.苔藓。T. harzianum引起Ze、IAA、ACC、SA、JA和阿坝的系统增加。T. harzianum和AMF与植物产生了一个特征性的激素概况，这不同于通过单独接种每种微生物产生的，表明植物响应的衰减，与激素SA，JA和乙烯有关。这些结果进行了讨论，他们参与生物量分配和基础抗枯萎病。(C)2010爱思唯尔有限公司版权所有。
Arbuscular mycorrhizal fungi (AMF) and Trichoderma harzianum are known to affect plant growth and disease resistance through interaction with phytohormone synthesis or transport in the plant. Cross-talk between these microorganisms and their host plants normally occurs in nature and may affect plant resistance. Simultaneous quantification in the shoots of melon plants revealed significant changes in the levels of several hormones in response to inoculation with T. harzianum and two different AMF (Glomus intraradices and Glomus mosseae). Analysis of zeatin (Ze), indole-3-acetic acid (IAA), 1-aminocyclopropane-1-carboxylic acid (ACC), salicylic acid (SA), jasmonic acid (JA) and abscisic acid (ABA) in the shoot showed common and divergent responses of melon plants to G. intraradices and G. mosseae. T. harzianum effected systemic increases in Ze, IAA, ACC, SA, JA and ABA. The interaction of T. harzianum and the AMF with the plant produced a characteristic hormonal profile, which differed from that produced by inoculation with each microorganism singly, suggesting an attenuation of the plant response, related to the hormones SA, JA and ethylene. These results are discussed in relation to their involvement in biomass allocation and basal resistance against Fusarium wilt. (C) 2010 Elsevier Ltd. All rights reserved.
