1. Rhizosphere pH and phosphorus forms in an Oxisol cultivated with soybean, brachiaria grass, millet and sorghum
Plants have shown different responses to fertilization with rock phosphate, including responses through alteration of the attributes of rhizospheric soil. The objective of this study was to evaluate soil pH alterations and alterations in the contents of forms of phosphorus in the rhizosphere of soil fertilized with rock phosphate as a result of cultivation o

2. Bactérias associadas a variedades de cana-de-açúcar cultivadas em Pernambuco: diversidade genética e produção de ácido indol acético. / Bacteria associated of varieties of sugar cane cultivated in Pernambuco: genetic diversity and indole acetic acid production.
A associação entre bactérias benéficas e plantas é considerada extremamente importante, pois pode promover o desenvolvimento do vegetal através da disponibilização de nutrientes, proteção e produção de substâncias promotoras de crescimento vegetal, como o ácido indol acético (AIA). A canade- açúcar é uma cultura de grande importância agrí

3. Interações entre bactérias endofíticas e do rizoplano com fungos causadores da murcha e cancro de Eucalyptus / Interactions among endophytic and rhizoplane bacteria with fungi that cause wilt and canker in Eucalyptus
Os microrganismos endofíticos são aqueles, cultiváveis ou não, que habitam o interior da planta hospedeira sem causar danos aparentes ou estruturas externas visíveis. Essa interação planta-microrganismo é intrínseca a determinadas espécies de plantas e/ou bactérias. Nas últimas décadas os estudos de microrganismos endofíticos têm sido realizad

5. Isolation, identification and evaluation of Pochonia chlamydosporia for controlling Meloidogyne javanica and promoting growth in tomato plants / Isolamento, identificação e avaliação de Pochonia chlamydosporia no controle de Meloidogyne javanica e na promoção de crescimento de tomateiro
Twenty-nine isolates of Pochonia chlamydosporia were found in Meloidogyne infested-soils samples of vegetables crops from Viçosa (MG), Mariópolis (PR) and Venda Nova do Imigrante (ES). Among them, 65.52 % were identified as P. chlamydosporia var. chlamydosporia and 34.48 % as P. chlamydosporia var. catenulata. The potential of these isolates including four

6. Effect of potato cultivars and pesticides application on the rDNA profiles of soil bacterial communities. / Efeito de cultivares de batata e de agrotóxicos sobre os perfis de rDNA de comunidades bacterianas do solo
Potato cropping shows great social and economical importance and, it is responsible by a very expressive part of the labor force of agricultural workers, besides being the forth product used as human food. Comercial potato cultivars show a great variety of characteristics related to maturation stage, accumulated dry matter content and disease resistance, whi

7. Seleção de rizobactérias como promotoras de crescimento e indutoras de resistência sistêmica em feijoeiro / Selection of rhizobacteria as growth-promoters and inducers of systemic resistance in bean
Two hundred rhizobacteria obtained from rhizosphere and rhizoplane of healthy looking bean plants were investigated for their ability to promote growth in bean plants, increase grain yield and induce systemic resistance against leaf pathogens. In growth-promoting assays, bean seeds (Ouro Negro) were microbiolized with a propagule suspension and next sown und

8. Mineralization Capacity of Bacteria and Fungi from the Rhizosphere-Rhizoplane of a Semiarid Grassland
A radiotracer glucose mineralization assay was used with streptomycin and actidione to monitor the relative seasonal contributions of bacteria and fungi to mineralization processes in soils derived from the rhizosphere-rhizoplane zone of plants from a shortgrass prairie ecosystem. Bacteria played a major role in glucose mineralization in both the rhizosphere

9. Comparison of Bacterial Community Structures in the Rhizoplane of Tomato Plants Grown in Soils Suppressive and Conducive towards Bacterial Wilt
It has been reported that the growth of Ralstonia solanacearum is suppressed at the rhizoplane of tomato plants and that tomato bacterial wilt is suppressed in plants grown in a soil (Mutsumi) in Japan. To evaluate the biological factors contributing to the suppressiveness of the soil in three treated Mutsumi soils (chloroform fumigated soil; autoclaved soil

10. Close Association of Azospirillum and Diazotrophic Rods with Different Root Zones of Kallar Grass
The populations of diazotrophic and nondiazotrophic bacteria were estimated in the endorhizosphere and on the rhizoplane of Kallar grass (Leptochloa fusca) and in nonrhizosphere soil. Microaerophilic diazotrophs were counted by the most-probable-number method, using two semisolid malate media, one of them adapted to the saline-sodic Kallar grass soil. Plate

11. Genetic and Phenotypic Diversity of Bacillus polymyxa in Soil and in the Wheat Rhizosphere
Diversity among 130 strains of Bacillus polymyxa was studied; the bacteria were isolated by immunotrapping from nonrhizosphere soil (32 strains), rhizosphere soil (38 strains), and the rhizoplane (60 strains) of wheat plantlets growing in a growth chamber. The strains were characterized phenotypically by 63 auxanographic (API 50 CHB and API 20B strips) and m

12. Persistence of Selected Spartina alterniflora Rhizoplane Diazotrophs Exposed to Natural and Manipulated Environmental Variability
Rhizoplane-rhizosphere nitrogen-fixing microorganisms (diazotrophs) are thought to provide a major source of biologically available nitrogen in salt marshes dominated by Spartina alterniflora. Compositional and functional stability has been demonstrated for this important functional group; however, the quantitative responses of specific diazotroph population
