Abstract
Morus alba L. has been worldwide cultivated and commercially exploited plant with profound potential in environmental management, food and medicinal industries. Plant-associated microbial communities are playing an essential role in sustainable plant development. In the present study, the bacterial and fungal microorganism populations distributed on the white mulberry fruits harvested in the Czech Republic for the first time were characterized by metagenomics approach. A total of 62 bacterial and 37 fungal families were identified on white mulberry. Bacterial population was represented by the genera Tatumella, Leuconostoc, Frateuria and Pseudomonas, while fungal microorganisms – by Hanseniaspora, Cryptococcus, Cladosporium and Phoma. Both potentially beneficial, inducing resistance in the hosting plant, and pathogenic, responsible for disease development, microorganisms were detected. The information on the prevalence of bacterial and fungal microorganisms on the carposphere of M. alba is highly relevant for the development of strategies for environment-friendly plant cultivation, disease management and prevention.
Highlights
Mulberry trees (Morus L.) have been widely cultivated in temperate and subtropical regions of Africa, America, Asia and Europe; their planting steadily increases every year due to realized economic and ecological benefits (Ou et al, 2019; Xu et al, 2019)
A few studies were focused on the characterization of bacterial community distributed on different Morus L. cultivars using culture-dependent (Xu et al, 2019) and metagenomics (Ou et al, 2019) approaches
It was demonstrated that the endophytic Morus L. microorganism assemblies are specific for the host plant and the climatic conditions (Ou et al, 2019)
Summary
Mulberry trees (Morus L.) have been widely cultivated in temperate and subtropical regions of Africa, America, Asia and Europe; their planting steadily increases every year due to realized economic and ecological benefits (Ou et al, 2019; Xu et al, 2019). Mulberry (Morus spp.) has been commercially exploited as the host of the silkworm (Bombyx mori). Mulberry leaves and fruits contain a variety of nutrient and nutraceutical substances. Fruits have been recognized as a kind of natural nutrition and functional food; they are usually eaten fresh or made into jam, juice and wine (Łochyńska, 2015). Due to the presence of anthocyanins, carotenoids and flavonoids, mulberry fruits possess potential pharmacological properties including. Rubra and nigra are the best-known mulberry species. The white mulberry (Morus alba L.) is very
