1. The genomes of three Bradyrhizobium sp. isolated from root nodules of Lupinus albescens grown in extremely poor soils display important genes for resistance to environmental stress
Abstract Lupinus albescens is a resistant cover plant that establishes symbiotic relationships with bacteria belonging to the Bradyrhizobium genus. This symbiosis helps the development of these plants in adverse environmental conditions, such as the ones found in arenized areas of Southern Brazil. This work studied three Bradyrhizobium sp. (AS23, NAS80 and N

2. Atividade de flavonoides sobre esporos do fungo micorrizico Giaspora gigantea in vitro.
Os flavonoides vegetais, alem de atuarem em diversos processos do crescimento e desenvolvimento das plantas, soa bastante ativos na relacao planta-microrganismos. Na simbiose rizobio-leguminosas, por exemplo, eles atuam como sinais moleculares ativando a transcricao de genes essenciais na interacao bacteria-planta. Apesar da acao estimulante de alguns flavon

3. Bioprospecting for Microbial Endophytes and Their Natural Products
Endophytic microorganisms are to be found in virtually every plant on earth. These organisms reside in the living tissues of the host plant and do so in a variety of relationships, ranging from symbiotic to slightly pathogenic. Because of what appears to be their contribution to the host plant, the endophytes may produce a plethora of substances of potential

4. The Elicitor Cryptogein Blocks Glucose Transport in Tobacco Cells1
Cryptogein is a 10-kD protein secreted by the oomycete Phytophthora cryptogea that induces a hypersensitive response on tobacco (Nicotiana tabacum var. Xanthi) plants and a systemic acquired resistance against various pathogens. The mode of action of this elicitor has been studied using tobacco cell suspensions. Our previous data indicated that within minute

5. Enhanced Mineralization of [U-14C]2,4-Dichlorophenoxyacetic Acid in Soil from the Rhizosphere of Trifolium pratense
Enhanced biodegradation in the rhizosphere has been reported for many organic xenobiotic compounds, although the mechanisms are not fully understood. The purpose of this study was to discover whether rhizosphere-enhanced biodegradation is due to selective enrichment of degraders through growth on compounds produced by rhizodeposition. We monitored the minera
