Cocoa ( L.) is a major agricultural commodity, essential for the global chocolate industry and the livelihoods of millions of farmers. However, viral diseases pose a significant threat to cocoa production, with Badnavirus species causing severe losses in Africa. Despite its economic importance, the overall virome of remains poorly characterized, limiting our understanding of viral diversity and potential disease interactions. This study aims to assess the cocoa-associated virome by analyzing 109 publicly available RNA-seq libraries from nine BioProjects, covering diverse conditions and geographic regions. We implemented a comprehensive bioinformatics pipeline integrating multiple viral sequence enrichment steps, a hybrid assembly strategy using different assemblers, and sequence similarity searches against NCBI non-redundant databases. Our approach identified ten putative novel viruses associated with the cocoa microbiome and a novel Badnavirus species. These findings provide new insights into the viral landscape of , characterizing the diversity of cacao-associated viruses and their potential ecological roles. Expanding the catalog of viruses associated with cocoa plants not only enhances our understanding of plant-virus-microbiome interactions but also contributes to the development of more effective disease surveillance and management strategies, ultimately supporting sustainable cocoa production.
可可(可可属)是一种主要的农产品,对全球巧克力产业以及数百万农民的生计至关重要。然而,病毒病对可可生产构成重大威胁,其中杆状DNA病毒属物种在非洲造成了严重损失。尽管可可具有经济重要性,但其整体病毒组仍未得到充分表征,这限制了我们对病毒多样性和潜在病害相互作用的理解。本研究旨在通过分析来自九个生物项目的109个公开可用的RNA测序文库来评估与可可相关的病毒组,这些文库涵盖了不同的条件和地理区域。我们实施了一个综合的生物信息学流程,该流程整合了多个病毒序列富集步骤、使用不同组装器的混合组装策略以及针对NCBI非冗余数据库的序列相似性搜索。我们的方法鉴定出了十种与可可微生物组相关的假定新型病毒以及一种新型杆状DNA病毒属物种。这些发现为可可的病毒景观提供了新的见解,描绘了与可可相关病毒的多样性及其潜在的生态作用。扩大与可可植物相关的病毒目录不仅能增强我们对植物 - 病毒 - 微生物组相互作用的理解,还有助于制定更有效的病害监测和管理策略,最终支持可持续的可可生产。
