马铃薯赤霉病(Common Scab，CS)是马铃薯生产中的一种重要病害和品质问题。CS降低了马铃薯块茎的外观，从而降低了市场价值。近年来，对CS的认识有了很大的扩展，使人们能够更好地检测致病病原体，加深了对致病机制的了解，并提供了潜在的方法来调节病原体对抗病的反应。然而，这种疾病的有效控制仍然是难以捉摸的，需要对宿主和病原体都有更多的了解。传统的控制策略，如灌溉和降低土壤pH值，是不够的，而且往往失败。优化减少CS的环境条件也可以为其他疾病创造有利条件。最理想的防治方法是抗病马铃薯品种。然而，目前还没有一个商品化的马铃薯品种被证明对CS完全抗性。本文综述了由植物病原链霉菌引起的马铃薯纹枯病的研究现状、发病机理和防治方法，以及如何有效控制马铃薯纹枯病的知识空白。
Common scab (CS) is an important disease and quality problem in potato crops worldwide. CS degrades the appearance of the potato tubers, thereby diminishing market value. Knowledge of CS has expanded considerably over recent years, enabling improved detection of the causal pathogens and increased understanding of mechanisms of pathogenicity, and providing potential methods of modulating pathogen response for disease resistance. However, effective control of this disease remains elusive, and will require increased understanding of both the host and the pathogen. Traditional control strategies such as irrigation and reduced soil pH are not sufficient and often fail. Optimizing environmental conditions for reduction of CS can also lead to favorable conditions for other diseases. The most desirable control method would be disease-resistant potato cultivars. However, no currently available commercial potato cultivar has been shown to be completely resistant to CS. In this review, we provide an overview of potato CS caused by plant pathogenic Streptomyces species, recent research on mechanisms and management of the disease, and knowledge gaps that limit successful control of this ubiquitous and troublesome disease.
