[Abstract]  Corn stalk rot caused by Fusarium spp., a genus of soil-borne fungal pathogens, has become a major concern of maize production. This disease normally causes significant reduction of maize yield and quality worldwide. The field assay for identifying stalk rot resistance using adult plants is largely relying on large population, yet time-consuming, labor costs, and often influenced by environmental conditions. Therefore, a rapid and reliable assay for investigating maize stalk rot caused by Fusarium spp. is required for screening the resistant lines and functional study of ... [摘要]  由镰刀菌属(一种土壤真菌病原体)引起的玉米茎腐病已成为玉米生产的主要问题。这种疾病通常会导致全球玉米产量和质量的显着降低。使用成年植物鉴定茎腐病抗性的田间试验在很大程度上依赖于大量人群,但费时费力,并且通常受环境条件的影响。因此,用于快速可靠的检测由镰刀霉属引起的玉米茎腐病的检测。是筛选玉米对这种病原体的抗性品系和功能研究所必需的。我们开发了一种幼苗分析方法,用12天到2周龄的幼苗快速筛选抗性品系。整个测定可以在种子萌发后约16-18天内完成,其中廉价的劳动力成本和高重复性。这种简单,快速和可靠的检测方法可以广泛用于鉴定玉米对由镰刀霉引起的茎腐病的抗性。和其他类似的真菌病原体。

【背景】玉米是全球最重要的主粮作物和能源植物之一。自2012年以来,它已成为中国乃至全世界第一大产量和种植面积的作物品种。然而,玉米秸秆腐烂已成为最具破坏性的疾病之一,其通常导致玉米产量大幅下降和玉米质量下降(Oerke,2006)。引起玉米秸秆腐烂的病原体主要包括土壤真菌物种,例如禾谷镰刀菌F, (Verticillioides), ...
