The Changing Face of Bacterial Soft-Rot Diseases

Bacterial soft rot is a disease complex caused by multiple genera of gram-negative and gram-positive bacteria, with Dickeya and Pectobacterium being the most widely studied soft-rot bacterial pathogens. In addition to soft rot, these bacteria also cause blackleg of potato, foot rot of rice, and bleeding canker of pear. Multiple Dickeya and Pectobacterium species cause the same symptoms on potato, complicating epidemiology and disease resistance studies. The primary pathogen species present in potato-growing regions differs over time and space, further complicating disease management. Genomics technologies are providing new management possibilities, including improved detection and biocontrol methods that may finally allow effective disease management. The recent development of inbred diploid potato lines is also having a major impact on studying soft-rot pathogens because it is now possible to study soft-rot disease in model plant species that produce starchy vegetative storage organs. Together, these new discoveries have changed how we face diseases caused by these pathogens.

细菌软腐病的变化面貌

细菌性软腐病是由多种革兰氏阴性菌和革兰氏阳性菌引起的疾病复合体,其中迪卡卡菌和果胶杆菌是研究最广泛的软腐菌病原体。这些细菌除软腐病外,还会引起马铃薯黑脚病,大米的脚腐烂病和梨的溃疡病。多重迪基氏菌油杆菌种在马铃薯上引起相同的症状,使流行病学和抗病性研究复杂化。马铃薯种植区中存在的主要病原体种类随时间和空间而变化,这进一步加剧了疾病管理。基因组学技术提供了新的管理可能性,包括改进的检测和生物控制方法,这些方法最终可以实现有效的疾病管理。近交二倍体马铃薯品系的最新发展对研究软腐病原体也产生了重大影响,因为现在有可能在产生淀粉质营养贮藏器官的模型植物中研究软腐病。这些新发现共同改变了我们面对这些病原体引起的疾病的方式。
