Isolation of endophytic streptomyces strains from surface-sterilized roots.
When the roots of 28 plant species were surface sterilized and incubated on agar medium, endophytic actinomycetes in the root cortex were observed by direct microscopic observation and pure culture techniques.
متن کاملHerbaspirillum hiltneri sp. nov., isolated from surface-sterilized wheat roots.
The genus Herbaspirillum of the Betaproteobacteria mainly comprises diazotrophic bacteria with a potential for endophytic and systemic colonization of a variety of plants. The plant-associated bacterial isolates N3(T), N5 and N9 were derived from surface-sterilized wheat roots. After phylogenetic analysis of 16S rRNA gene sequence data the isolates could be allocated to the genus Herbaspirillum...
متن کاملPseudonocardia kunmingensis sp. nov., an actinobacterium isolated from surface-sterilized roots of Artemisia annua L.
A Gram-positive, aerobic, actinobacterial strain with rod-shaped spores, designated YIM 63158(T), was isolated from the surface-sterilized roots of Artemisia annua L. collected from Yunnan province, south-west China. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain YIM 63158(T) belonged to the genus Pseudonocardia. The closest neighbours were 'Pseudonocardia sichuanensi...
متن کاملNon-Frankia actinomycetes isolated from surface-sterilized roots of Casuarina equisetifolia fix nitrogen.
Based on partial 16S sequences, we previously described a novel group of nonsymbiotic, acetylene reduction activity-positive actinomycetes which were isolated from surface-sterilized roots of Casuarina equisetifolia growing in Mexico. An amplified rRNA restriction analysis confirmed that these actinomycetes are distinct from Frankia, a finding substantiated by a 16S rRNA gene phylogenetic analy...
متن کاملComplete Genome Sequence of Herbaspirillum hiltneri N3 (DSM 17495), Isolated from Surface-Sterilized Wheat Roots
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.
