With the aim of searching for potent diazotrophic bacteria that are free of public health concerns and optimize rice cultivation, the endophytic colonization and plant growth-promoting activities of some endophytic diazotrophic bacteria isolated from rice were evaluated. Among these bacteria, the emerging diazotrophic strains of the genus Novosphingobium effectively associated with rice plant interiors and consequently promoted the growth of rice, even with the lack of a nitrogen source. These results suggest that diazotrophic Novosphingobium is an alternative microbial resource for further development as a safe biological enhancer in the optimization of organic rice cultivation...

Nitrogen (N) fixation through legume-Rhizobium symbiosis is important for enhancing agricultural productivity and is therefore of great economic interest. Growing evidence indicates that other soil beneficial bacteria can positively affect symbiotic performance of rhizobia. Nodule endophytic plant growth promoting rhizobacteria (PGPR) were isolated from common bean nodules from Nakuru County in Kenya and characterized 16S rDNA partial gene sequencing. The effect of co-inoculation of rhizobium and PGPR, on nodulation and growth of common bean (Phaseolus vulgaris L...

The fungus Xylaria arbuscula was isolated as an endophyte from Cupressus lusitanica and has shown to be a prominent producer of cytochalasans, mainly cytochalasin C, D and Q. Cytochalasans comprise an important class of fungal secondary metabolites that have aroused attention due to their uncommon molecular structures and pronounced biological activities. Due to the few published studies on the ESI-MS/MS fragmentation of this important class of secondary metabolites, in the first part of our work we studied the cytochalasin D fragmentation pathways using an ESI-Q-ToF mass spectrometer coupled with liquid chromatography...

The mechanisms that trigger the switch from endophytic fungi to saprophytic fungi are largely unexplored. Broad host range Phomopsis liquidambari is established in endophytic and saprophytic systems with rice (Oryza sativa L.). Endophytic P. liquidambari promotes rice growth, increasing rice yield and improving the efficiency of nitrogen fertilizer. This species's saprophytic counterpart can decompose rice litterfall, promoting litter organic matter cycling and the release of nutrients and improving the soil microbial environment...

Similar to mycorrhizal mutualists, the rhizospheric and endophytic fungi are also considered to act as active regulators of host fitness (e.g., nutrition and stress tolerance). Despite considerable work in selected model systems, it is generally poorly understood how plant-associated fungi are structured in habitats with extreme conditions and to what extent they contribute to improved plant performance. Here, we investigate the community composition of root and seed-associated fungi from six halophytes growing in saline areas of China, and found that the pleosporalean taxa (Ascomycota) were most frequently isolated across samples...

Taxol (paclitaxel) is a diterpenoid compound with significant and extensive applications in the treatment of cancer. The production of Taxol and relevant intermediates by engineered microbes is an attractive alternative to the semichemical synthesis of Taxol. In this study, based on a previously developed platform, we first established taxadiene production in mutant E. coli T2 and T4 by engineering of the mevalonate (MVA) pathway. We then developed an Agrobacterium tumefaciens-mediated transformation (ATMT) method and verified the strength of heterologous promoters in Alternaria alternata TPF6...

Despite the recent surge in mitochondrial (mt) genome sequencing, Kingdom Fungi remains underrepresented with respect to mtDNA. We describe the mt genome of the conifer needle endophyte, Phialocephala scopiformis DAOMC 229536 (Helotiales, Ascomycota). This strain is of interest to the Canadian forestry industry as it produces the anti-insectan compound rugulosin. Sequence was obtained from whole genome shotgun sequencing. Comparison to the only other published Phialocephala mt genome, Phialocephala subalpina, indicates that the suite of common mt genes - cox1-3, cob, nad1-6 and 4L, atp6, 8 and 9, as well as rrnL and rrnS - has retained an identical order...
