Frankia sp. strain CcI49 was isolated from Casuarina cunninghamiana nodules. However the strain was unable to re-infect Casuarina, but was able to infect other actinorhizal plants including Elaeagnaceae. Here, we report the 9.8-Mbp draft genome sequence of Frankia sp. strain CcI49 with a G+C content of 70.5 % and 7,441 candidate protein-encoding genes. Analysis of the genome revealed the presence of a bph operon involved in the degradation of biphenyls and polychlorinated biphenyls.
Permanent Draft Genome Sequence Of Frankia Sp. Nrrl B-16219 Reveals The Presence Of Canonical Nod Genes, Which Are Highly Homologous To Those Detected In Candidatus Frankia Dg1 Genome, Amir Ktari, Imen Nouioui, Teal Furnholm, Erik Swanson, Faten Ghodhbane-Gtari, Louis S. Tisa, Maher Gtari

Frankia sp. NRRL B-16219 was directly isolated from a soil sample obtained from the rhizosphere of Ceanothus jepsonii growing in the USA. Its host plant range includes members of Elaeagnaceae species. Phylogenetically, strain NRRL B-16219 is closely related to “Frankia discariae” with a 16S rRNA gene similarity of 99.78%. Because of the lack of genetic tools for Frankia, our understanding of the bacterial signals involved during the plant infection process and the development of actinorhizal root nodules is very limited. Since the first three Frankia genomes were sequenced, additional genome sequences covering more diverse strains have helped provide insight into …

Background: Soil salinization is a worldwide problem that is intensifying because of the effects of climate change. An effective method for the reclamation of salt-affected soils involves initiating plant succession using fast growing, nitrogen fixing actinorhizal trees such as the Casuarina. The salt tolerance of Casuarina is enhanced by the nitrogen-fixing symbiosis that they form with the actinobacterium Frankia. Identification and molecular characterization of salt-tolerant Casuarina species and associated Frankia is imperative for the successful utilization of Casuarina trees in saline soil reclamation efforts. In this study, salt-tolerant and salt-sensitive Casuarina associated Frankia strains were identified and comparative genomics, transcriptome …
Pb2+ Tolerance By Frankia Sp. Strain Ean1pec Involves Surface-Binding, Teal Furnholm, Medhat Rehan, Jessica Wishart, Louis S. Tisa
Pb2+ Tolerance By Frankia Sp. Strain Ean1pec Involves Surface-Binding, Teal Furnholm, Medhat Rehan, Jessica Wishart, Louis S. Tisa
Molecular, Cellular & Biomedical Sciences
Several Frankia strains have been shown to be lead-resistant. The mechanism of lead resistance was investigated for Frankia sp. strain EAN1pec. Analysis of the cultures by scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDAX) and Fourier transforming infrared spectroscopy (FTIR) demonstrated that Frankia sp. strain EAN1pec undergoes surface modifications and binds high quantities of Pb +2 . Both labelled and unlabelled shotgun proteomics approaches were used to determine changes in Frankia sp. strain EAN1pec protein expression in response to lead and zinc. Pb 2+ specifically induced changes in exopolysaccharides, the stringent response, and the phosphate (pho) regulon. Two metal …

Frankia sp. strain KB5 was isolated from Casuarina equisetifolia and previous studies have shown both nitrogenase and uptake hydrogenase activities under free-living conditions. Here, we report 5.5-Mbp draft genome sequence with a G+C content of 70.03 %, 4,958 candidate protein-encoding genes, and 2 rRNA operons.
