... of PABP1 during the phase of recovery from heat shock may be neces- sary to meet the cellular demand for protein synthesis for complete recovery from stress. Results PABP1 expression during recovery ... TOP cis-element of PABP1 mRNA is involved in the upregulation of PABP1 mRNA translation during recovery from heat shock. Previous studies have shown...

... Induction of ctt1, encoding catalase, and apt1, encoding a 25 kDa protein, but not that of gpx1, encoding glutathione peroxidase, was indistinguishable in four ubiquinone-deficient mutants, indicating ... phenotypes were indis- tinguishable from those of other ubiquinone-deficient Sc. pombe mutants, which argues against a possible role for demethoxyubiquinone in respiration. Result...

... simulated antagonism. The expression of agn13.2 during in vivo assays against the strawberry pathogen Botrytis cinerea strongly supports the role of AGN13.2 in the antagonistic action of T. asperellum. Results Biochemical ... with this idea, it is worth mention- ing that both strains display clear distinctive host range and antagonistic abilities in controlled assays (unpub-...
