Tomato Plant Microbiota under Conventional and Organic Fertilization Regimes in a Soilless Culture System

Tomato is the main vegetable cultivated under soilless culture systems (SCSs); production of organic tomato SCSs has increased due to consumer demands for healthier and environmentally friendly vegetables. However, been associated with low crop performance fruit quality defects. These agricultural deficiencies could be linked alterations in plant microbiota; nonetheless, this issue not sufficiently addressed. Thus, goal present study was characterize rhizosphere phyllosphere plants conventional SCSs. To accomplish goal, grown commercial greenhouses or were tested at 8, 26, 44 weeks after seedling transplantation. Substrate (n = 24), root 24) composite samples subjected DNA extraction high-throughput 16S rRNA gene sequencing. The revealed that core microbiota predominantly constituted by Proteobacteria, Actinobacteria, Firmicutes. Remarkably, six bacterial families, Bacillaceae, Microbacteriaceae, Nocardioidaceae, Pseudomonadaceae, Rhodobacteraceae, Sphingomonadaceae, shared among all substrate, rhizosphere, samples. Importantly, it shown undergo a dysbiosis characterized significant changes relative abundance Bradyrhizobiaceae, Caulobacteraceae, Chitinophagaceae, Enterobacteriaceae, Erythrobacteraceae, Flavobacteriaceae, Streptomycetaceae. results suggest microbial substrates, roots, fruits potential factors contributing observed
