The molecular mechanisms of plant recognition, colonization, and nutrient exchange between diazotrophic endophytes and plants are scarcely known. Herbaspirillum seropedicae is an endophytic bacterium capable of colonizing intercellular spaces of grasses such as rice and sugar cane. The genome of H. seropedicae strain SmR1 was sequenced and annotated by The(More)
Diazotrophic species in the genus Herbaspirillum (e.g. H. frisingense, H. rubrisubalbicans and H. seropedicae) associate with several economically important crops in the family Poaceae, such as maize (Zea mays), Miscanthus, rice (Oryza sativa), sorghum (Sorghum bicolor) and sugarcane (Saccharum sp.), and can increase their growth and productivity by a(More)
Rice (Oryza sativa L.) is the primary source of carbohydrate for the majority of the World's population. Herbaspirillum seropedicae is a diazotroph that lives within and on the surface of rice roots. It can promote the growth of rice, partly by supplying it with fixed nitrogen. To better understand the rice–H. seropedicae interaction, cDNA libraries from(More)
Herbaspirillum spp. are endophytic diazotrophic bacteria associated with important agricultural crops. In this work, we analyzed six strains of H. seropedicae (Z78, M2, ZA69, ZA95, Z152, and Z67) and one strain of H. rubrisubalbicans (M4) by restriction fragment length polymorphism (RFLP) using HindIII or DraI restriction endonucleases, random amplified(More)
The acidic peatlands of southern Brazil are ecosystems essential for the maintenance of the Atlantic Forest, one of the 25 hot-spots of biodiversity in the world. In this work, we investigated the composition of prokaryotic communities in four histosols of three acidic peatland regions by constructing small-subunit (SSU) rRNA gene libraries and sequencing.(More)
Herbaspirillum rubrisubalbicans was first identified as a bacterial plant pathogen, causing the mottled stripe disease in sugarcane. H. rubrisubalbicans can also associate with various plants of economic interest in a non pathogenic manner. A 21 kb DNA region of the H. rubrisubalbicans genome contains a cluster of 26 hrp/hrc genes encoding for the type(More)
Here we report the one-scaffold draft genome of Herbaspirillum huttiense subsp. putei strain 7-2 T (IAM 15032), which was isolated from well water. Draft genome sequence of Herbaspirillum huttiense subsp. putei IAM 15032, a strain isolated from well water. H erbaspirillum huttiense subsp. putei strain 7-2 T (IAM 15032) is a betaproteobacterium isolated from(More)
Herbaspirillum seropedicae is a diazotrophic bacterium which associates endophytically with economically important gramineae. Flavonoids such as naringenin have been shown to have an effect on the interaction between H. seropedicae and its host plants. We used a high-throughput sequencing based method (RNA-Seq) to access the influence of naringenin on the(More)
Aeromonas spp. are Gram-negative rods ubiquitous in aquatic environments; however, some species are able to cause a variety of infections in humans. Here, we report the draft genome sequence of Aeromonas caviae 8LM isolated from stool culture from a child with diarrhea in southern Brazil.
We report the complete genome sequence of Herbaspirillum hiltneri N3 (DSM 17495), a member of the genus Herbaspirillum of the Betaproteobacteria. The genome is contained in a single chromosome, and analysis revealed that N3 lacks the whole nitrogen fixation (nif) gene cluster, confirming its inability to fix nitrogen.
