摘要：基因芯片技术因能对生物样本进行快速、高通量的定性和定量分析,而在植物病害诊断中也得到普遍的应用[1]。树木溃疡病是指引起木本植物树皮上出现溃疡腐烂等症状的病害[2]。引起杨树溃疡病的真菌种类较多,加之其无性型和有性型多样,所以,关于杨树溃疡病病原菌的报道多有不同。另外,受地理位置、寄主植物关系及分类体系的限制,迫切需要发展不依赖于常规分离培养的病原鉴定新技术。
[ Objective ] Using ArrayTube, a high-throughput microarray technology, to detect poplar canker patho- gens in Beijing area. [ Method] The DNA extracted from symptomatic and asymptomatic poplar bark were used to hybridizing by ArrayTube. The results of hybridization were recorded and analyzed by IconoClust-AT 3.0. Then the hybridization results were verified by cloning of the corresponding tissue. [ Result] The results showed that Botryo- sphaeria dothidea and Valsa sordida were successfully detected as the target pathogens in symptomatic samples by microarray hybridization. The B. dothidea was also found as an endophyte in healthy tissue. [ Conclusion ] The re- sults indicated that the ArrayTube technique is an effective method for quick detection of poplar canker pathogens, it could be further applied in other forest plant pathogen detection or diagnosis.
