[Abstract]  Aphids constitute a large group of Hemipterans that use their slender stylets to tap into the sieve elements of plants from which they consume copious amounts of phloem sap, thus depriving the plant of photoassimilates. Some aphids also transmit viral diseases of plants. Myzus persicae Sülzer, commonly known as the green peach aphid (GPA), which is a polyphagous insect with a host range that covers 50 plant families, is considered amongst the top 3 insect pest of plants. The interaction between Arabidopsis thaliana and the GPA is utilized as a model pathosystem to study plant-aphid interaction. Here we describe the protocol used in our laboratories for rearing the GPA, and no-choice and fecundity bioassays to study GPA performance on Arabidopsis. In addition, we ... [摘要]  蚜虫构成了一大群半翅目,它们使用细长的探针进入植物的筛子元素,从而消耗大量的韧皮部汁液,从而剥夺了植物的光合同化物。 一些蚜虫也传播植物的病毒性疾病。 桃蚜(Myzus persicae)Sülzer,俗称绿桃蚜(GPA),是一种多食性昆虫,寄主范围覆盖50个植物科,被认为是植物的三大害虫之一。 拟南芥与GPA之间的相互作用被用作研究植物 - 蚜虫相互作用的模型病理系统。 在这里,我们描述了我们的实验室用于饲养GPA的方案,以及用于研究拟南芥的GPA性能的无选择和繁殖生物测定。 此外,我们描述了电穿透图(EPG)技术的程序,以监测GPA在拟南芥上的摄食行为。

【背景】蚜虫是植物的重要害虫,它们利用它们的口器被改造成管心针,以从筛子元件中去除韧皮部汁液。作为其饲养过程的一部分,蚜虫将唾液沉积到植物组织中。虽然一些唾液成分引发植物防御,但其他驯鹿成分则操纵宿主生理学以使昆虫受益,包括抑制植物防御(Nalam et al。,2018)。植物利用各种防御来控制蚜虫侵扰。这些包括抗生素,它对蚜虫的生长,发育和繁殖以及影响昆虫行为(包括摄食行为)的抗病毒产生不利影响。当探针尖端在植物细胞内时,以及当探针尖端在筛子元件中时,这些防御在各个步骤施加,包括在细胞表面,在昆虫探针的叶组织细胞间穿透期间(Nalam 等人,,2018)。绿桃蚜(GPA), Myzus ...

Establishment of a Fusarium graminearum Infection Model in Arabidopsis thaliana Leaves and Floral Tissues

[Abstract]  Fusarium graminearum (Fg) is the causal agent of Fusarium head blight disease of wheat (Triticum aestivum), oats (Avena sativa) and barley (Hordeum vulgare), which targets the floral tissues and thereby adversely impacts grain yield and quality. Mycotoxins produced by F. graminearum further limit the consumability of infected grain. In the laboratory, F. graminearum also has the ability to colonize both leaves and inflorescence tissues of Arabidopsis thaliana. The interaction between A. thaliana and F. graminearum makes available a large array of genetic and molecular tools to study the interaction between plants and F. graminearum to elucidate plant genes and pathways that contribute to resistance, ... [摘要]  禾谷镰刀菌(Fg)是小麦(小麦),燕麦( Avena sativa )和大麦镰刀菌 ),其针对花组织,从而不利地影响谷物产量和质量。由F生产的霉菌毒素。禾谷镰菌进一步限制了感染谷物的消耗性。在实验室,F。禾谷镰刀菌也具有定居拟南芥的叶和花序组织的能力。 A之间的交互。 thaliana 和 F。禾谷镰刀菌(graminearum)提供了大量遗传和分子工具来研究植物和真菌之间的相互作用。禾本科(Graminearum)来阐明植物基因和促进抗性的途径,以及研究真菌如何靶向植物基因和促进疾病的机制。下面描述的方法允许有效地感染拟南芥叶和花序,以及评价疾病进展和真菌生长。拟南芥中的病害传播可以通过叶组织的萎黄病和花序组织的包括真菌团块在花序组织表面上的病害表型的视觉观察来容易地监测。可以通过聚合酶链反应(PCR)和定量实时PCR(qPCR)测量宿主组织中的Fg DNA的相对量来进一步监测真菌生长。
