Mulberry bacterial wilt is a serious destructive soil-borne disease caused by a complex and diverse group of pathogenic bacteria. Given that the bacterial wilt has been reported to cause a serious damage to the yield and quality of mulberry, therefore, elucidation of its main pathogenic groups is essential in improving our understanding of this disease and for the development of its potential control measures.
In this study, combined metagenomic sequencing and culture-dependent approaches were used to investigate the microbiome of healthy and bacterial wilt mulberry samples.
The results showed that the healthy samples had higher bacterial diversity compared to the diseased samples. Meanwhile, the proportion of opportunistic pathogenic and drug-resistant bacterial flora represented by in the diseased samples was increased, while the proportion of beneficial bacterial flora represented by was decreased. species complex (RSSC), complex (ECC), , , , , and emerged as the main pathogens of the mulberry bacterial wilt.
In conclusion, this study provides a valuable reference for further focused research on the bacterial wilt of mulberry and other plants.
桑细菌性枯萎病是一种由复杂多样的致病细菌引起的严重破坏性土传病害。鉴于细菌性枯萎病已被报道对桑树的产量和质量造成严重损害，因此，阐明其主要致病菌群对于增进我们对该病害的理解以及制定潜在的防治措施至关重要。
在本研究中，采用宏基因组测序和基于培养的方法相结合，对健康和患细菌性枯萎病的桑树样本的微生物群落进行研究。
结果表明，与患病样本相比，健康样本具有更高的细菌多样性。同时，患病样本中以[具体细菌名称1]为代表的机会性致病和耐药菌群比例增加，而以[具体细菌名称2]为代表的有益菌群比例下降。[具体细菌名称3]种复合体（RSSC）、[具体细菌名称4]复合体（ECC）、[具体细菌名称5]、[具体细菌名称6]、[具体细菌名称7]、[具体细菌名称8]和[具体细菌名称9]成为桑细菌性枯萎病的主要病原菌。
总之，本研究为进一步聚焦研究桑树及其他植物的细菌性枯萎病提供了有价值的参考。
