Akkermansia transcriptome response to mucin and/or glucose growth medium

Transcriptome analysis comparing the gene expression of A. muciniphila grown on mucin or glucose media confirmed the activity of the genes involved in mucin degradation, and revealed most of them to be upregulated in the presence of mucin. A. muciniphila grown on glucose showed a stress response and upregulation of specific genes, such as Amuc_1094 which was identified as a glucokinase induced by glucose. The transcriptional response was confirmed by a proteome analysis, reinforcing the adaptation of A. muciniphila to the mucosal environment. These new findings provide molecular insights into the lifestyle of A. muciniphila, and further confirm its role as a mucin specialist in the gut

Resposta de híbridos simples de milho à redução do espaçamento entre linhas Response of maize single-cross hybrids to reduced row spacing

O objetivo deste trabalho foi avaliar o efeito da redução do espaçamento entre linhas no rendimento de grãos, nos componentes de rendimento e em outras características agronômicas de híbridos simples de milho. Foram conduzidos dois experimentos no Município de Eldorado do Sul, na região fisiográfica da Depressão Central do Estado do Rio Grande do Sul. No ano agrícola de 1997/98, os tratamentos constaram de dois híbridos simples de milho (Cargill901 e BraskalbXL212) e de quatro espaçamentos entre linhas (40, 60, 80 e 100 cm). Em 1998/99, foram testados dois híbridos simples de milho (Cargill901 e BraskalbXL214) em duas densidades de plantas (50.000 e 65.000plantas/ha) e em quatro espaçamentos entre linhas (40, 60, 80 e 100 cm). O rendimento foi influenciado pelo híbrido e pela densidade de plantas. O aumento do rendimento ocorreu principalmente em híbridos de baixa estatura e na densidade de 50.000 plantas/ha.<br>The objective of this work was to determine the effects of using narrow row spacing on grain yield, grain components and on other agronomic traits of maize single-cross hybrids. Two experiments were conducted in the state of Rio Grande do Sul, Brazil. In the 1997/98 growing season, treatments were composed by two singlecross hybrids (Cargill901 and BraskalbXL212) and four row spacings (40, 60, 80 and 100 cm). In the 1998/99growing season, two single-cross hybrids were tested at two plant densities (50,000 and 65,000pl./ha) and four row spacings (40, 60, 80 and 100 cm). Maize grain yield was influenced by hybrid and plant density. The reduction in row spacing promoted a high grain yield specially for hybrids with a low plant height sown at the density of 50,000pl./ha
