Antioxidant Enzymes Activities

Phosphite-based fungicides are a group of chemicals that are directly harmless to the environment and have a direct fungicide effect, while also indirectly stimulating the plant immune response. Potato late blight is one of the most destructive potatoes diseases globally, causing many morphological and physiological changes in potato leaves and tubers. In current experiment, the potato plants with three-time spray of potassium phosphite (KPhi) on potato leaves, following three months in storage, and inoculated with late blight were investigated. This study examined the possible role of KPhi in delays of late blight invasion and physiological responses including the reactive oxygen species (ROS) metabolism in potato tubers after challenging with late blight pathogen. Samples were collected at 0, 24, 48, 72 and 96 hours of time points for evaluations. Antioxidant enzymes such as superoxidase dismutase (SOD), peroxidase (POD) and catalase (CAT), in addition content of metabolites such as phytoalexin and phenolic after infection with pathogen was investigated. Meanwhile, KPhi treatment resulted in plant tolerance with improved resistance, increased antioxidant enzymes activities and non-enzymatic compounds compare to untreated plants under similar stress. The results of this study indicate that the role of KPhi reduces the adverse effects of pathogens, suppress potato late blight and improves antioxidant enzymes activities and non-enzymatic compounds in potato tubers.

There have been numerous indications since the 1990s that oospore-derived primary infections play an increasing role in the epidemiology of potato late blight. The aim of this study was to verify that oosporederived epidemics actually occur in Finland. For this purpose, 20 suspected foci of oospore-derived potato late blight were scouted in 2000–2002. All of these were located in fi elds in which late blight had been observed in at least one of the four previous years. Primary symptoms in these foci occurred always on the lowest leaves near or touching the ground. Leafl ets typically showing numerous primary infections or lesions were in direct contact with the soil. In the former, oospores were observed after incubation. Soil samples from two experimental fi elds, marked by severe epidemics in most years during the last decade, caused infections in a bioassay. Both mating types were on every occasion present in groups of single lesion isolates collected from foci and the bioassay. Oospores survived over the winter, as shown by soil samples taken during the spring that infected potato leafl ets in the bioassay. The results presented indicate that oospore-derived epidemics occur in Finland. This paper also discusses the role of oospores in causing blight epidemics in Finland compared to more southern countries.;
