| 1 | Post-Translational Derepression of Invertase Activity in Source Leaves via Down-Regulation of Invertase Inhibitor Expression Is Part of the Plant Defense Response显示文摘正在增加病原体做的证据不仅得到直接防卫回答,而且在主要糖类新陈代谢引起显著变化。Cell-wall-bound 转化酶属于糖类划分和来源水池关系的关键管理者。而研究到目前为止响应病原体感染仅仅集中了于转化酶基因的 transcriptional 正式就职,转化酶活动的 translational 以后规定的角色被忽视了并且是现在的学习的焦点。表示分析表明高 mRNA 在 Arabidopsis thaliana 的来源叶子从三个 proteinaceous 转化酶禁止者一个铺平被 Pseudomonas syringae pv 的剧毒的紧张强烈在感染之上镇压。西红柿 DC3000。这压抑是由在转化酶禁止者活动的减少的 paralleled。这规章的机制的生理的角色被发现那在由 P 的感染之上仅仅在 situ 转化酶活动是可检测的揭示。syringae。相反,一项高转化酶活动能在 vitro 被测量在粗略并且准备从的房间墙摘录感染并且非感染的叶子。差异在之间在里面 situ 并且在在 situ 的控制叶子和高度的 vitro 转化酶活动,在感染的叶子的转化酶活动能被转化酶禁止者表示和伴随物减小的病原体依赖者压抑在转化酶禁止者活动解释。从为防卫反应的 translational 以后抑制的转化酶的版本的功能的重要性被竞争化学转化酶禁止者 acarbose 的申请证实。由在叶子的 acarbose 的渗入的细胞外的转化酶活动的 translational 以后抑制被显示增加危险性到 P。syringae。光合作用的压抑和细菌的生长的提升的空间、时间的动力学上的转化酶抑制的影响在植物防卫为细胞外的转化酶在病原体感染期间支持一个角色。危险性的调停 acarbose 的增加在 sid2 和 cpr6 异种也是可检测的并且导致了水杨酸酸的稍微提高的层次,证明效果独立于水杨酸调整酸的防卫小径。这些调查结果为在来源叶子发现被使蛋白质被在转化酶和转化酶禁止者之间的 translational 以后相互作用在 situ 禁止了的高可引出的转化酶活动提供解释。在病原体感染之上,转化酶活动被转化酶禁止者表示的压抑释放,因此连接水池力量的本地正式就职到植物防卫反应。 | Katharina B.

| 7 | Unveiling plant defense arsenal: metabolic strategies in Brassica oleracea during black rot disease显示文摘Alterations in plant metabolism play a key role in the complex plant-pathogen interactions.However,there is still a lack of knowledge about the connection between changes in primary and specialized metabolism and the plant defense against diseases that impact crops.Thus,we aim to study the metabolic reprograming in Brassica oleracea plants upon infection by Xanthomonas campestris pv.campestris(Xcc).To accomplish this,we utilized a combination of untargeted and targeted metabolomics,through UPLC-Q-TOF-MS/MS and 1H-NMR,in two crop lines differing in resistance thatwere evaluated at two-and four-week intervals following inoculation(T1 and T2,respectively).Besides,to depict the physiological status of the plant during infection,enzymatic activities related to the carbohydrate pathway and oxidative stress were studied.Our results revealed different temporal dynamics in the responses of the susceptible vs.resistant crops lines.Resistant B.oleracea line suppresses carbohydrate metabolism contributing to limit nutrient supplies to the bacterium and prioritizes the induction of defensive compounds such as indolic glucosinolates,salicylic acid,phenylpropanoids and phytoalexins precursors at early infection stages.In contrast,the susceptible line invests in carbohydratemetabolism,including enzymatic activities related to the hexoses turnover,and activates defense signaling related to reactive oxygen species.Thus,each line triggers a different metabolic strategy that will affect how the plant overcomes the disease in terms of resistance and growth.This work provides first insights of a fine-tuned metabolic regulation during Xcc infection in B.oleracea that will contribute to develop new strategies for plant disease management. | Carmen Vega-Álvarez Pilar Soengas Thomas Roitsch Rosaura Abilleira Pablo Velasco Marta Francisco | 2023 | Horticulture Research2023，10，11： | 0 |
