番茄品种Micro-Tom是一种微型番茄，在植物分子生物学和生理学研究中具有许多优势。为了评价Micro-Tom作为寄主植物用于致病性研究的适合性，将Micro-Tom植物接种16种已知的番茄真菌、细菌和病毒病原体：致病疫霉和核盘菌在Micro-Tom上表现典型症状并大量产孢。Micro-Tom对Alternaria alternata、Corynespora ducicola和Fusarium oxysporum等病害具有抗性。用17个青枯菌菌株接种Micro-Tom，许多菌株诱发枯萎症状，根癌农杆菌也具有致病性，针刺接种后茎组织产生冠瘿。在Micro-Tom上分别用番茄假单胞菌、烟粉虱假单胞菌和番茄假单胞菌进行接种。大豆致病变种（s.pv. glycoprotein）的叶片上，细菌数量没有增加，只有叶面喷施P.番茄花叶病毒（Tomato mosaic virus）、番茄无精病毒（Tomato aspermy virus）和黄瓜花叶病毒（Cucumber mosaic virus）系统感染Micro-Tom，Micro-Tom在感染相应病毒后表现出其它番茄品种特有的症状。这些结果表明，Micro-Tom对大多数重要番茄病原菌普遍感病，并表现出典型的症状，而某些病原菌在Micro-Tom上受到超敏抗性或非寄主抗性的限制。因此，各种各样的Micro-Tom-pathogen系统应该为研究植物和病原菌之间的感病和抗病相互作用机制提供很好的模型。
Lycopersicon esculentumcultivar Micro-Tom is a miniature tomato with many advantages for studies of the molecular biology and physiology of plants. To evaluate the suitability of Micro-Tom as a host plant for the study of pathogenesis, Micro-Tom plants were inoculated with 16 well-known fungal, bacterial, and viral pathogens of tomato.Athelia rolfsii,Botryotinia fuckeliana,Oidiumsp.,Phytophthora infestans, andSclerotinia sclerotiorumcaused typical symptoms and sporulated abundantly on Micro-Tom. Micro-Tom was resistant toAlternaria alternata,Corynespora cassiicola, andFusarium oxysporum. When Micro-Tom was inoculated with 17 isolates ofRalstonia solanacearum, many isolates induced wilt symptoms.Agrobacterium tumefaciensalso was pathogenic, causing crown galls on stem tissue after needle prick inoculation. In Micro-Tom sprayed withPseudomonas syringaepv.tomato,P. s.pv.tabaci, orP. s.pv.glycinea, bacterial populations did not increase, and yellow lesions appeared only on leaves sprayed withP. s.pv.tomato.Tomato mosaic virus,Tomato aspermy virus, andCucumber mosaic virussystemically infected Micro-Tom, which developed symptoms characteristic of other cultivars of tomato after infection with the respective virus. These results indicated that Micro-Tom was generally susceptible to most of the important tomato pathogens and developed typical symptoms, whereas certain pathogens were restricted by either hypersensitive resistance or nonhost resistance on Micro-Tom. Therefore, an assortment of Micro-Tom–pathogen systems should provide excellent models for studying the mechanism of susceptible and resistant interactions between plants and pathogens.
