| We studied the microhabitats and the climatic requirements of six Drosera taxa, which occur in the subtropical grasslands of the Tibagi river basin. They are annual,or most communly, perennial herbs known as carnivorous plants, whose leaves are transformed into traps for the capture and digestion of small insects as an adaptation for supplying nutricional deficiencies. They usually occur in distrophic substrata. In order to contribute to conservation plans for the species of the genus, threatened by the conversion of the natural grasslands into pastures, we tried to define their preferential habitats and climatic requirements. We verified that the variables of microhabitat and altitude presented significant correlation at 5% probability level, while the... |

| The objective of this work was to assess the effect of two strains of Bacillus thuringiensis var. kurstaki on sorghum rhizosphere microorganisms. The strains were HD1, that produces the bioinsecticidal protein, and 407, that is a mutant non-producer. The strains do not influence microbial population, but reduce plant growth and improve mycorrhizal colonization and free living fixing N2 community. |

| Quatro isolados bacterianos da rizosfera de Drosera villosa var. villosa (B1, B2, B3, B4) e dois isolados de Bacillus thuringiensis (B5 e B6), sendo B6 produtor da toxina bioinseticida Cry1Ab, foram avaliados quanto à capacidade de inibir os fungos fitopatogênicos Fusarium solani f. sp. phaseoli, Fusarium solani f. sp. glycines, Fusarium oxysporum e Colletotrichum sp. A cepa mais efetiva foi B1 que inibiu o crescimento dos quatro fungos até o 26º dia. B. thuringiensis inibiu o crescimento de três destes, o que indica que possui atividade antifúngica e abre um novo campo de estudo para a utilização do B. thuringiensis. |

| Some diazotrophic bacteria can fix nitrogen biologically in gramineous host plants. Generally, gramineous plants are also associated with mycorrhizal fungi, that can improve mainly plant P uptake. Among the factors affecting plant-microbe interactions, the plant genotype plays an important role. This study evaluates the effect of diazotrophic bacteria and an arbuscular mycorrhizal fungus (AMF), on five genotypes of maize (Zea mays L.), in relation to plant biomass, shoot N and P concentrations, and fine root morphological traits. The experimental design was entirely randomized in a factorial 5 × 4 × 2 arrangement, i.e., five maize genotypes (hybrids C333B, AS3466, and PREMIUM, and the inbreed lines lg40897-1 and lg40505-1), three diazotrophic bacteria... |
