Survival of plants in such conditions as rapid temperature drops and rises in the range of 20 °C or more depends on their biochemical defense system's ability to quickly respond to such stress, as well as on the plant's structural features. Therefore, our goal was to analyze changes of biochemical parameters under conditions of abrupt hyperthermia in four species of Crassula linne genus and to establish the connection between their anatomical and morphological features and the peculiarities of the biochemical reactions. Plants of Crassula brevifolia Harvey, Crassula lanuliginosa Harvey, Crassula muscosa Linne and Сrassula perfoliata var. minor (haworth) G.d. rowley species were held in air thermostats at 40 °C and 50 °C for 3 h, the control temperature being 26 °C. Stress response was analyzed by malondialdehyde content, superoxide dismutase and peroxidase activity and pigments content. additionally, anatomical structure of the leaves was investigated. Antioxidant response to short-term high temperature varied in different species of the Crassula genus by its directionality and intensity, and depended on the anatomical features of the plant. The additional protective mechanisms were involved in the least heat-resistant plants, such as increased carotenoids and flavonoids contents. More powerful SOD and peroxidase activities under rapid heating in plants with more effective protection at the anatomical level were showed.","PeriodicalId":23448,"journal":{"name":"Ukrainian Biochemical Journal","volume":"92 1","pages":"111-123"},"PeriodicalIF":0.0,"publicationDate":"2020-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43634546","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study was to investigate the state of oxidative phosphorylation at Ca2+induced activation of mPTP in permeabilized hepatocytes. Hepatocytes were isolated by two-stage Seglen method. Permeabilization was performed using digitonin. Oxygen consumption rate was measured with Clark electrode. Oxidative phosphorylation was determined as the ratio of the aDP-stimulated respiration and substrate-stimulated respiration rates (aDP/S). It was established that increasing of Ca2+ concentration in the medium inhibited oligomycin effects and suppressed ADPand FCCP-stimulated respiration upon succinate or glutamate, pyruvate and malate mixture oxidation. The mPTP inhibitor cyclosporin a did not directly affect respiration and oxidative phosphorylation after elevation of Ca2+ concentration and mPTP activation. When cyclosporine a was added before increasing Ca2+ concentration, the electron transport chain function (FCCP-stimulated respiration) was not impaired while the partial disruption of oxidative phosphorylation (aDP-stimulated respiration) was observed only upon succinate oxidation. The results obtained showed that inhibition of oxidative phosphorylation was the primary event in mPTP activation, possibly due to the involvement of ATP synthase in pore opening. In the case of NAD-dependent substrates oxidation that effect was stronger and faster than at succinate oxidation, due to the lower mitochondria energization.","PeriodicalId":23448,"journal":{"name":"Ukrainian Biochemical Journal","volume":"92 1","pages":"14-23"},"PeriodicalIF":0.0,"publicationDate":"2020-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41611517","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
