Sweet potato is a subsistence crop cultivated worldwide. Although it is generally considered tolerant to different diseases, it is quite susceptible to the fungus Plenodomus destruens that causes foot-rot disease. Plant growth-promoting bacteria associated with sweet potato remain poorly studied, but some Bacillus strains may have potential as biological control agents. Here, we evaluate the persistence of two bacterial strains?Bacillus safensis T052-76 and Bacillus velezensis T149-19?in pot experiments and assess their impact on indigenous bacterial and fungal communities associated with sweet potato. Numbers of cells of both strains introduced into pots remained stable in the rhizosphere of sweet potato over the 180-day experiment. Denaturing gradient gel electrophoresis based on the rrs gene encoding bacterial 16S rRNA and the fungal ribosomal internal transcribed spacer region showed that bands corresponding to the introduced strains were not detected in plant endosphere. PERMANOVA and non-metric multidimensional scaling statistical analyses showed that: (1) strain T052-76 altered the structure of the indigenous bacterial community (rhizosphere and soil) more than strain T149-19; (2) T052-76 slightly altered the structure of the indigenous fungal community (rhizosphere and soil) and (3) strain T149-19 did not disturb the fungal community. Our results demonstrate the stability of both Bacillus strains in the sweet potato rhizosphere and, apart from the influence of B. safensis T052-76 on the bacterial community, their limited impact on the microbial community associated with this important crop plant.

Abstract. Epigenetic repression has been linked to the regulation of different cell states. In this study, we focus on the influence of this repression, mainly by H3K27me3, over gene expression in muscle cells, which may affect mineral content, a phenotype that is relevant to muscle function and beef quality. Based on the inverse relationship between H3K27me3 and gene expression (i.e., epigenetic repression) and on contrasting sample groups, we computationally predicted regulatory genes that affect muscle mineral content. To this end, we applied the TRIAGE predictive method followed by a rank product analysis. This methodology can predict regulatory genes that might be affected by repressive epigenetic regulation related to mineral concentration. Annotation of orthologous genes, between human and bovine, enabled our investigation of gene expression in the Longissimus thoracis muscle of Bos indicus cattle. The animals under study had a contrasting mineral content in their muscle cells. We identified candidate regulatory genes influenced by repressive epigenetic mechanisms, linking histone modification to mineral content in beef samples. The discovered candidate genes take part in multiple biological pathways, i.e., impulse transmission, cell signalling, immunological, and developmental pathways. Some of these genes were previously associated with mineral content or regulatory mechanisms. Our findings indicate that epigenetic repression can partially explain the gene expression profiles observed in muscle samples with contrasting mineral content through the candidate regulators here identified.
