The effect of benzothiadiazole and fungal extracts of Cercospora beticola and Fusarium graminearum on phosphoenolpyruvate carboxylase activity in cucumber leaves
Abstract The cytosolic phosphoenolpyruvate carboxylase (PEPC) catalyses the anaplerotic synthesis of oxalacetic acid resulting in the replenishment of citric acid cycle intermediates, which are precursors for the synthesis of amino acids. Biotic stress in plants generally leads to redistributions in...

| 520 | |a Abstract The cytosolic phosphoenolpyruvate carboxylase (PEPC) catalyses the anaplerotic synthesis of oxalacetic acid resulting in the replenishment of citric acid cycle intermediates, which are precursors for the synthesis of amino acids. Biotic stress in plants generally leads to redistributions in primary and secondary pathways and therefore to a shift in the requirement of proteins. To reveal whether and how PEPC is affected by biotic stress we analysed PEPC activity after treating cucumber (Cucumis sativus) leaves with the synthetic plant activator benzothiadiazole (BTH) and extracts of the economically important phytopathogenic fungi Cercospora beticola and Fusarium graminearum. BTH as well as fungal extracts increased PEPC activity significantly 72 and 96 hours after treatments. In addition, the extracts, but not BTH, induced the formation of necrotic lesions. Defence responses are generally associated with decreased photosynthesis rates, an enhanced respiration rate and an increased demand in proteins. Regarding our results we assume that the increase in PEPC activity by biotic stress is conducive to a compensation of these antagonistic processes. However, PEPC activity enhancements are not necessarily associated with the formation of necrotic lesions. This study indicates that PEPC is involved in biotic stress responses and we suggest that PEPC contributes to successful defence responses in plants. | ||

Biotic stress in plants generally leads to redistributions in primary and secondary pathways and therefore to a shift in the requirement of proteins. To reveal whether and how PEPC is affected by biotic stress we analysed PEPC activity after treating cucumber (Cucumis sativus) leaves with the synthetic plant activator benzothiadiazole (BTH) and extracts of the economically important phytopathogenic fungi Cercospora beticola and Fusarium graminearum. BTH as well as fungal extracts increased PEPC activity significantly 72 and 96 hours after treatments. In addition, the extracts, but not BTH, induced the formation of necrotic lesions. Defence responses are generally associated with decreased photosynthesis rates, an enhanced respiration rate and an increased demand in proteins. Regarding our results we assume that the increase in PEPC activity by biotic stress is conducive to a compensation of these antagonistic processes. However, PEPC activity enhancements are not necessarily associated with the formation of necrotic lesions. This study indicates that PEPC is involved in biotic stress responses and we suggest that PEPC contributes to successful defence responses in plants.

Biotic stress in plants generally leads to redistributions in primary and secondary pathways and therefore to a shift in the requirement of proteins. To reveal whether and how PEPC is affected by biotic stress we analysed PEPC activity after treating cucumber (Cucumis sativus) leaves with the synthetic plant activator benzothiadiazole (BTH) and extracts of the economically important phytopathogenic fungi Cercospora beticola and Fusarium graminearum. BTH as well as fungal extracts increased PEPC activity significantly 72 and 96 hours after treatments. In addition, the extracts, but not BTH, induced the formation of necrotic lesions. Defence responses are generally associated with decreased photosynthesis rates, an enhanced respiration rate and an increased demand in proteins. Regarding our results we assume that the increase in PEPC activity by biotic stress is conducive to a compensation of these antagonistic processes. However, PEPC activity enhancements are not necessarily associated with the formation of necrotic lesions. This study indicates that PEPC is involved in biotic stress responses and we suggest that PEPC contributes to successful defence responses in plants.</subfield></datafield><datafield tag="700"

| abstract |
Abstract The cytosolic phosphoenolpyruvate carboxylase (PEPC) catalyses the anaplerotic synthesis of oxalacetic acid resulting in the replenishment of citric acid cycle intermediates, which are precursors for the synthesis of amino acids. Biotic stress in plants generally leads to redistributions in primary and secondary pathways and therefore to a shift in the requirement of proteins. To reveal whether and how PEPC is affected by biotic stress we analysed PEPC activity after treating cucumber (Cucumis sativus) leaves with the synthetic plant activator benzothiadiazole (BTH) and extracts of the economically important phytopathogenic fungi Cercospora beticola and Fusarium graminearum. BTH as well as fungal extracts increased PEPC activity significantly 72 and 96 hours after treatments. In addition, the extracts, but not BTH, induced the formation of necrotic lesions. Defence responses are generally associated with decreased photosynthesis rates, an enhanced respiration rate and an increased demand in proteins. Regarding our results we assume that the increase in PEPC activity by biotic stress is conducive to a compensation of these antagonistic processes. However, PEPC activity enhancements are not necessarily associated with the formation of necrotic lesions. This study indicates that PEPC is involved in biotic stress responses and we suggest that PEPC contributes to successful defence responses in plants. © Deutsche Phythomedizinische Gesellschaft 2007 |
