TL;DR: A modulation of F. oxysporum gene expression in response to the interaction with the ectosymbiotic bacteria is demonstrated, suggesting that the inability of WT strain to penetrate the plant roots could be due to alterations in the expression profile of cell wall-degrading enzymes.

TL;DR: Six mutants of Azospirillum brasilense Sp6 unable to fix nitrogen have been isolated and characterized and analysis of the enzymes involved in nitrogen metabolism has shown that the mutants are deficient in glutamate synthase activity.

TL;DR: Genetic, molecular and electrophoretic karyotyping data indicated that interspecific hybrids were obtained, and it was concluded that fertile asci could derive from allotetraploid cells generated by endomitotic events in allodiploids cells, a mechanism that enables overcoming the species barrier between S. cerevisiae and S. bayanus.

TL;DR: Seven spontaneous Saccharomyces cerevisiae mutants that express dominant resistance to 5,5,5-trifluoro-DL-leucine have been characterised at the molecular level, and a region, the R-region, involved in both leucine feedback inhibition and in Zn2+-mediated inactivation by CoA is defined.

TL;DR: The isolates described here exhibit a biodegradation potential towards monocyclic aromatic compounds of OMWs that is markedly broader and higher than that displayed by other aerobic bacteria described previously, which makes them excellent candidates for removing the low-molecular-weight phenolic compounds persisting in the effluent following anaerobic digestion of O MWs.
