0 experimento foi conduzido na Embrapa Caprinos, Sobral, CE, Brasil com o objetivo de determinar os efeitos da suplementaçao alimentar e do sistema de acasalamento sobre 0 desempenho produtivo de matrizes ovinas crioulas criadas em caatinga manipulada, em urn delineamento experimental inteiramente casualizado, sob 0 sistema de pastoreio rotativo e com uma taxa de lotaçao medio de 3,6 ovinos/ha/ano. A suplementaçao alimentar, ministrada durante a estaçao seca, constou de 200 g de rolao de milho e 300 g de feno de leucena e os sistemas de acasalamento foram a manta continua, a manta anual e a manta a cada oito meses. Na fase de pre-manta, as matrizes nao suplementadas tiveram pesos vivos medias (PVM), na estaçao umida, superiores (P<0,05) aos da estaçao seca, enquanto que as suplementadas tiveram PVM semelhantes (P>0,05), mas, superiores (P<0,05) aos das nao suplementadas, somente na estacao seca. Ao pre-parto, pos-parto e a desmama, os PVM das matrizes suplementadas superaram (P<0,05) os das nao suplementadas, independentemente da estaçao do ano. A fertilidade ao parto na epoca das chuvas foi de 86,3% para as matrizes suplementadas e de 72,7% para as nao suplementadas, enquanto na epoca seca os valores foram de 75,8% e 60,0%, respectivamente. A taxa media de prolificidade foi de 1,64 crias/ano para as matrizes nao suplementadas e 1,77 para as suplementadas. As reprodutrizes suplementadas desmamaram anualmente 15,6 kg PVM de cordeiros e as nao suplementadas 10,6 kg. |

The extracellular space in plants, termed the apoplast, has a pH and sugar content that enables bacterial growth and represents a possible niche for the establishment of endophytic bacteria. Previous studies have investigated the effects of diazotrophic bacteria inoculation in sugarcane varieties, but it has not yet been analyzed how the microbial community of apoplast fluid of sugarcane is affected. High-throughput next generation sequencing of the 16S rRNA gene was used throughout this study to determine the effect of inoculation with a diazotrophic bacteria consortium, previously isolated from sugarcane, on the native bacterial population of sugarcane variety RB867515 grown in the field. The analyses were carried out 450 days after inoculation. The results revealed the presence of 22 phyla, with predominance of Proteobacteria phylum. It was observed that the inoculated consortium changed the indigenous bacterial community structure of sugarcane apoplast fluid by decreasing diversity and evenness, interfering in the composition of rare species. Microbial community composition analysis revealed differences between treatments. The differential abundance test showed there were 43 amplicon sequence variants (ASVs) which were relatively more abundant in the inoculated treatment, with predominance of the Sphingomonas genus. The pre-dicted functions of the most abundant ASVs revealed the presence of genera related to plant growth promotion and protection against phytopathogens. Analysis to evaluate the occurrence of inoculated strains in the recovered data was not conclusive since the ASVs taxonomically close to the inoculated bacteria were observed in low abundance. The present study is the first report to elucidate the bacterial community in sugarcane apoplast fluid using a culture-independent approach. It demonstrated that the diazotrophic bacterial consortium interferes in the natural bacterial community in sugarcane variety RB867515 MenosThe extracellular space in plants, termed the apoplast, has a pH and sugar content that enables bacterial growth and represents a possible niche for the establishment of endophytic bacteria.
