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)
Endophytic bacteria live inside plant tissues without causing disease. Studies of endophytes in sugarcane have focused on the isolation of diazotrophic bacteria. We examined the diversity of endophytic bacteria in the internal tissues of sugarcane stems and leaves, using molecular and biochemical methods. Potato-agar medium was used to cultivate 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)
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)
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)
Despite the development in DNA sequencing technology, improving the number and the length of reads, the process of reconstruction of complete genome sequences, the so called genome assembly, is still complex. Only 13% of the prokaryotic genome sequencing projects have been completed. Draft genome sequences deposited in public databases are fragmented in(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.
