Abstract
Chinese Jujube (Ziziphus jujuba) is a widely cultivated fruit tree with significant economic and ecological importance. However, Jujube trees face the threat of canker diseases caused by various pathogens during cultivation. In this study, we investigated destructive canker diseases affecting Z. jujuba in Beijing, China. Through morphological comparison and DNA sequence analysis, we identified the causal organisms of these diseases as Dothiorella acericola and Nothophoma spiraeae. This study represents the first report of D. acericola and N. spiraeae on Z. jujuba, contributing to our understanding of the fungal species associated with canker or dieback diseases on this important tree species. The findings also provide valuable insights for the development of effective disease management strategies for Z. jujuba in China.
Plain Language Summary
The Chinese Jujube is an economically important fruit tree that can be seriously damaged by canker diseases, which cause sores on its bark and branches. Researchers in Beijing, China, studied these diseases to find the cause. By examining the physical traits and DNA of the fungi present, they identified two species, Dothiorella acericola and Nothophoma spiraeae, as the culprits. This is the first time these particular fungi have been reported to cause disease on jujube trees. This finding is crucial for understanding the threats to this crop and for developing effective strategies to manage the disease.
