Quatro cultivares de arroz (EEA 304, SUVALE 1, IRGA 408 e CICA 4) foram selecionadas em solucao nutritiva para tolerancia a aluminio, em concentracoes de 0, 10, 20, 40 e 60 ppm de A1. Os sintomas de toxidez foram caracterizados visualmente, pela producao de materia seca da parte aerea e raizes, altura de planta e comprimento da raiz. Foi observada uma tolerancia diferenciada ao A1 entre as cultivares. A cultivar EEA 304 foi tolerante ao aluminio, enquanto as outras apresentaram a seguinte ordem decrescente de susceptibilidade: SUVALE 1

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.
