AbstractNext-generation sequencing is recognized as one of the most popular and cost-effective way of characterizing microbiome in multiple samples. However, most of the currently available amplicon sequencing approaches are inherently limited, as they are often presented based on the relative abundance of microbial taxa, which may not fully represent actual microbiome profiles. Here, we combined amplicon sequencing (16S rRNA gene for bacteria and ITS region for fungi) with real-time quantitative PCR (qPCR) to characterize the rhizosphere microbiome of wheat. We show that the increase in relative abundance of major microbial phyla does not necessarily result in an increase in abundance. One striking observation when comparing relative and quantitative abundances was a substantial increase in the abundance of almost all phyla associated with the rhizosphere of plants grown in soil with no history of water stress as compared with the rhizosphere of plants growing in soil with a history of water stress, which was in contradiction with the trends observed in the relative abundance data. Our results suggest that the estimated absolute abundance approach gives a different perspective than the relative abundance approach, providing complementary information that helps to better understand the rhizosphere microbiome.

<p><strong>Resumo: </strong>O trabalho tem como preocupação a implantação da disciplina de Educação Física nas escolas do município de Ituiutaba (Triângulo Mineiro), no período entre 1934 e 1971. A adoção de atividades físicas nos currículos escolares com o objetivo de disciplinar e higienizar a juventude e a infância local refletia o novo ideal pedagógico voltado ao domínio dos “instintos insubordinados”, buscando-se normatizar condutas e contribuindo para a nova organização social, surgida com a sociedade urbana e industrial, especialmente a partir da Segunda Guerra Mundial. Tal contexto provocou a necessidade de desenvolvimento de um alto grau de eficiência produtiva, onde a educação escolar seria fundamental para atingir tal propósito, além de contribuir para a difusão da idéia de que era necessário garantir uma “educação higiênica” no combate aos grandes surtos epidêmicos. A partir dessa perspectiva, buscamos apontar as especificidades das práticas de professores e alunos nas aulas de Educação Física nas escolas desse município mineiro.</p><p><strong>Palavras-chave:</strong> História da Educação – História da Educação Física – Triângulo Mineiro.</p><p><strong> </strong></p><p><strong>Abstract: </strong>This article is concerned about the implementation of Physical Education in schools in the city Ituiutaba (<em>Triângulo Mineiro</em>) between 1934 and 1971. The adoption of physical activities in school curriculums aimed to <em>discipline</em> and <em>purify</em> the local youth and children reflected the new pedagogical ideal directed to the control of the "insubordinate instincts", seeking to regulate behaviors and contributing to the new social organization which appeared with the urban and industrial society, especially after the Second World War. Such a context brought about the need for development of a high degree of productive efficiency, where schooling would be essential to achieve such purpose, beyond the contribution to the transmission of the idea which was necessary to ensure a "pure education" in the fight against large epidemic outbreaks. From this perspective, we highlight the specific practices of teachers and students in Physical Education classes in the schools of this city.</p><p><strong>Keywords:</strong> History of Education – History of Physical Education ­– Triângulo Mineiro.</p>
