phytophthora austrocedrae sp. nov., a new species associated with austrocedrus chilensis mortality in patagonia (argentina). | phytophthora austrocedrae is a new species isolated from necrotic lesions of stem and roots of austrocedrus chilensis. it is a homothallic species characterized by semipapillate sporangia, oogonia with amphigynous antheridia, and very slow growth (1-2 mm d(-1) on v-8 agar at 17.5 degrees c optimum temperature). phylogenetic analysis of its rdna sequence indicates that its closest relative is phytophthora syringae, another species frequently isolated from soil and streams in a. chilensis forests. | 2007 | 17368010 |
isolation, characterization and structure-elicitor activity relationships of hibernalin and its two oxidized forms from phytophthora hibernalis carne 1925. | three alpha-elicitins, named hibernalin1, hibernalin2 and hibernalin3 (hib1, hib2 and hib3, respectively), were isolated by reverse phase-low-pressure liquid chromatography from culture filtrates of phytophthora hibernalis carne 1925, the causal agent of citrus lemon brown rot. hib1 proved to be identical to syringicin previously isolated from culture filtrates of phytophthora syringae. hib2 and hib3 shared the same primary structure with hib1, but contained, at position 50, met sulphoxide or su ... | 2008 | 17977856 |
