Stringent response mutants of Pseudomonas chlororaphis PA23 exhibit enhanced antifungal activity against Sclerotinia sclerotiorum in vitro.
The stringent response (SR) is a regulatory mechanism that enables bacteria to adapt to nutrient stress through the production of the alarmone (p)ppGpp. The aim of the current study was to understand how the SR affects the antifungal (AF) activity of Pseudomonas chlororaphis PA23. Two SR mutants were generated, PA23relA and PA23relAspoT, that no longer produced (p)ppGpp. Both mutants exhibited ...
متن کاملbeta glucanase (bgn13.1) expressed in transgenic brassica napus confers antifungal activity against sclerotinia sclerotiorum
brassica napus is an important oilseed crop and the yield loss due to fungal disease stem rot caused by sclerotinia sclerotiorum is a serious problem in cultivation of this crop. the pathogenesis-related (pr) protein, glucanase, hydrolyzes a major cell wall component, glucan, of the pathogenic fungi and acts as a plant defense barrier. in this study, a β-1,3-glucanase (bgn13.1) gene was isolate...
متن کاملEnhancement of Trichoderma Harzianum Activity Against Sclerotinia sclerotiorum by Overexpression of Chit42
Backgoround: Plant diseases, caused by a wide range of phytopathogenic fungi, could be managed using of Trichoderma sp, as a biocontrol agent. Cell wall degrading enzymes like chitinase from T. harzianum are important means for fungal pathogen inhibition. Overexpression of these chitinase enzymes can i...

backgoround: plant diseases, caused by a wide range of phytopathogenic fungi, could be managed using of trichoderma sp, as a biocontrol agent. cell wall degrading enzymes like chitinase from t. harzianum are important means for fungal pathogen inhibition. overexpression of these chitinase enzymes can improve the antagonistic potential of trichoderma sp. strains. objectives: this study aimed to ...
متن کاملMetabolism of crucifer phytoalexins in Sclerotinia sclerotiorum: detoxification of strongly antifungal compounds involves glucosylation.
The strongly antifungal phytoalexins brassilexin and sinalexin were metabolized by the stem rot fungus Sclerotinia sclerotiorum to glucosyl derivatives, whereas the phytoalexins brassicanal A, spirobrassinin and 1-methoxyspirobrassinin, displaying lower antifungal activity, were transformed via non-glucosylating pathways. Significantly, these transformations led to metabolites displaying no det...
