| identification of a major locus conferring resistance to powdery mildew (erysiphe polygoni dc) in mungbean (vigna radiata l. wilczek) by qtl analysis. | a major locus conferring resistance to the causal organism of powdery mildew, erysiphe polygoni dc, in mungbean (vigna radiata l. wilczek) was identified using qtl analysis with a population of 147 recombinant inbred individuals. the population was derived from a cross between 'berken', a highly susceptible variety, and atf 3640, a highly resistant line. to test for response to powdery mildew, f7 and f8 lines were inoculated by dispersing decaying mungbean leaves with residual conidia of e. poly ... | 2003 | 14608390 |

| effect of powdery mildew infection on photosynthesis by leaves and chloroplasts of sugar beets. | chloroplasts isolated from powdery mildew-infected (erysiphe polygoni dc) sugar beet leaves (beta vulgaris l) showed a reduction in the rate of electron transport and in the accompanying atp formation in noncyclic photophosphorylation (water as electron donor, nadp as electron acceptor) and little or no change in the rate of atp formation in cyclic photophosphorylation catalyzed by phenazine methosulfate. the inhibition of noncyclic photophosphorylation appeared to lead in the parent leaves to a ... | 1976 | 16659511 |
| effects of powdery mildew infection on the efficiency of co(2) fixation and light utilization by sugar beet leaves. | sugar beet leaves (beta vulgaris l.) infected with powdery mildew (erysiphe polygoni d.c.) show declining rates of net photosynthesis as the disease develops; relative to healthy controls, reductions of 35, 70, and 75% were observed at 9, 16, and 22 days after inoculation, respectively. a leaf gas exchange procedure in which an air stream flowed through the leaf showed that mesophyll conductance declined in parallel with photosynthesis in mildew-infected leaves. viscous flow conductance of disea ... | 1982 | 16662146 |
| resistance to erysiphe polygoni of red clover infected with bean yellow mosaic virus. | the development of erysiphe polygoni on leaves of red clover was retarded by poor infection with bean yellow mosaic virus. conidia germinated on leaves infected with the virus but disintegrated following necrosis of the leaf tissue in the immediate area of the germinating conidia. | 1964 | 17832405 |

| resistance to fungal pathogens triggered by the cf9-avr9 response in tomato and oilseed rape in the absence of hypersensitive cell death. | summary in tomato and related species, the cf9 resistance gene induces hypersensitive cell death and activates downstream defence pathways upon recognition of the avr9 elicitor. we investigated whether the cf9-avr9 response without hypersensitive cell death symptoms increases resistance to several fungi. a low avr9 dose that does not cause hypersensitive cell death was injected in cf9 tomato and transgenic cf9 oilseed rape plants. subsequently, the injected leaves were infected with different fu ... | 2002 | 20569306 |
