柑桔疫霉属（Phytophthora）是柑桔茎流胶病和根腐病的两种病原菌。在这项研究中，一个被忽视的地方柑橘称为广柑（柑橘）被确定为强抗病原体之一，烟草疫霉。接种后一周内所有叶片外植体和50%的活体接种茎段在一个月内无明显症状。用游动孢子囊和游动孢子悬浮液浸泡土壤不会导致盆栽广干幼苗的树木生长和叶片叶绿素含量的任何减少。实时荧光定量PCR分析表明，该菌株对P.可能与一些防御相关基因的高基础和诱导表达有关，特别是PR3基因。结果表明，C.网状的。光甘是一种很有开发利用价值的柑橘抗疫材料。
Two closely related pathogens ofPhytophthoraare responsible for stem gummosis and root rot diseases inCitrusworldwide. In this study, a neglected local mandarin called Guanggan (Citrus reticulata) was identified to be strongly resistant to one of the pathogens,P. nicotianae. No visible symptom was seen on all leaf explants within one week or on 50% ofin vivoinoculated stems within one month after inoculation with the pathogen. Drenching of the soil with zoosporangial and zoospore suspensions did not cause any reduction in tree growth and leaf chlorophyll content of pot-grown Guanggan seedlings. Quantitative real-time PCR analysis suggested that its resistance toP. nicotianaemay be associated with high basal and induced expression of some defense-related genes, particularly thePR3gene. In conclusion,C. reticulatavar. Guanggan is a promising material that can be exploited to improvePhytophthoraresistance inCitrus.
