Magnaporthe grisea produces an infection structure called appressorium, which is used to breach the plant cuticle by mechanical force. Appressoria generate hydrostatic turgor accumulating molar concentrations of glycerol. To investigate genetic control and biochemical mechanism for generation, we assayed glycerol biosynthetic enzymes during appressorium development, movement storage reserves was monitored in developmental mutants. Enzymatic activities generation from carbohydrate sources...
ABSTRACT The gray mold fungus Botrytis cinerea is a major threat to fruit and vegetable production. Strawberry fields usually receive several fungicide treatments against per season. Gray isolates from German strawberry-growing regions were analyzed determine their sensitivity botryticides. Fungicide resistance was commonly observed, with many possessing multiple (up six) fungicides. A stronger variant of the previously described multidrug (MDR) phenotype MDR1, called MDR1h, found be widely...
Botrytis cinerea is a major plant pathogen, causing gray mold rot in variety of cultures. Repeated fungicide applications are common but have resulted the development fungal populations with resistance to one or more fungicides. In this study, we monitored frequencies and occurrence multiple isolates from raspberries, strawberries, grapes, stone fruits ornamental flowers Germany 2010 2015. High all classes botryticides was cultures, represented part populations. A monitoring raspberry field...
A strain harbouring an insertion within the promoter of CON7 gene Magnaporthe grisea was isolated. This previously shown to be essential for appressorium formation and growth in planta is predicted encode a transcription factor. Microarray-based expression analysis used identify several genes whose during germination depends on Con7p. These include pathogenicity factor-encoding PTH11 other which like are G protein-coupled receptors. Microarray also revealed Con7p-dependent may factors...
During the vegetation period 2010, 353 isolates of Botrytis cinerea from 23 Northern German strawberry, raspberry, highbush blueberry, and redcurrant fields were examined for sensitivity to benzimidazole derivative thiophanate-methyl dicarboximide iprodione, as well five fungicides currently used against gray mold in Germany. Of all isolates, 40.5% highly resistant thiophanate-methyl, 64.0% 45.0% fenhexamid, 76.8% trifloxystrobin, 21.5% boscalid, 14.7% cyprodinil. No high resistance...
ABSTRACT Botrytis cinerea is one of the most important pathogens worldwide, causing gray mold on a large variety crops. pseudocinerea has been found previously to occur together with B. in low abundance vineyards and strawberry fields. Here, we report be common sometimes dominant over several fruit vegetable crops Germany. On apples calyx end rot oilseed rape, it was major species. Abundance often negatively correlated fungicide treatments. cultivated strawberries, frequently spring but...
Sooty blotch and flyspeck (SBFS) fungi colonize the surface wax layer of fruit apple, pear, persimmon, banana, orange, papaya, several other cultivated tree vine crops. In addition to colonizing crops, SBFS also grow on surfaces stems, twigs, leaves, a wide range wild plants. The disease occurs worldwide in regions with moist growing seasons. is regarded as serious by growers plant pathologists because it can cause substantial economic damage. smudges stipples often result downgrading from...
ABSTRACT Botrytis cinerea causes pre- and postharvest decay of many fruit vegetable crops. A survey German strawberry fields revealed strains that differed from B. in diagnostic PCR markers growth appearance. Phylogenetic analyses showed these belong to an undescribed species clade 2, named fragariae sp. nov. Isolates B . were detected throughout Germany, sometimes at frequencies similar those , the southeastern United States. was isolated overwintering tissue but not freshly infected fruit....
Abstract Background European canker, caused by Neonectria ditissima , is a disease of worldwide importance in apple production, yet knowledge about it limited, highly regional and sometimes contradictory. This an obstacle to successful management. Key aspects for Northern Europe are reviewed, based on research results from Germany Norway international literature data. Main topics Trunk cankers developing young trees within the first 1–3 seasons explanting can often be traced back latent...
