Burkholderia has only recently been recognized as a potential nitrogen-fixing symbiont of legumes, but we find that the origins symbiosis in are much deeper than previously suspected. We sampled 143 symbionts from 47 native species Mimosa across 1800 km central Brazil and found 98% were Burkholderia. Gene sequences defined seven distinct divergent complexes within genus The symbiosis-related genes formed deep Burkholderia-specific clades, each specific to complex, implying these diverged...
• An extensive survey of nodulation in the legume genus Mimosa was undertaken two major biomes Brazil, Cerrado and Caatinga, both which there are high degrees endemicity genus. Nodules were collected from 67 70 spp. found. Thirteen species newly reported as nodulating. examined by light electron microscopy, all except for M. gatesiae had a structure typical effective nodules. The endosymbiotic bacteria nodules identified Burkholderia via immunolabelling with an antibody against phymatum...
The purpose of the present study is to evaluate influence different handling systems, microbial population and its activity. To that end, soil samples were collected in October 2006 March 2007, at Fazenda Sereno city Jaciara, Mato Grosso State. removed 0-10 cm deep with four replications five areas systems: agriculture-livestock integration, corn/soy fields, pastures, native vegetation, vegetation under recovery. method Chloroform Fumigation-Incubation (CFI) was used biomass carbon (MBC)...
The production of sweets and similar sugarcane products is an activity performed by smallholder farmers from Acorizal, Cuiabá, Jangada, Nossa Senhora do Livramento, Santo Antônio Leverger, in Mato Grosso. Therefore, this study aimed to assess the socioeconomic productive aspects rural producers (individuals and/or families) that work with derivatives municipalities ‘Baixada Cuiabana’ region. 145 questionnaires were applied period March 2019 January 2020. Among main results, it was verified...
The genus Discolobium comprises forage legumes indigenous to the Brazilian Pantanal. Over 80% of Pantanal areas flood during wet season, and stem root nodules showing high biological N2 fixation rates result in protein content plants, representing a major component animals’ diet this area. In nature it is possible recognize species based on some phenotypic properties, as size, shape viscosity leaflets fruit morphology. However, when cropped under controlled environmental conditions such...
This study aimed to characterize rhizobia isolates of root and stem nodules Discolobium spp., a native legume Pantanal. Ten isolated were randomly chosen from the culture collection Soil Microbiology Laboratory Federal University Mato Grosso. The parameters evaluated were: growth in YM medium with different salt concentrations (0%, 1.5% 3%), initial pH levels (6.8, 3.0 9.0), two temperatures (28 39 °C), mucus production. analyses showed that all tolerant salinity temperature °C. alkaline...
O gênero Discolobium compreende leguminosas forrageiras nativas do Pantanal brasileiro, a maior área de terras naturalmente inundadas mundo. Quase 80% das áreas são submetidas alagamento durante estação chuvas, e nódulos no caule nas raízes com altas taxas fixação biológica N2 resultam em teores elevados proteína, representando um componente importante da dieta animal. Na natureza é possível reconhecer plantas por alguns sinais fenotípicos, como o tamanho, forma pegajosidade dos folíolos...
