(Sel. 184) plant, with marked transients induced by light on-off. A study of this potential and the transients was made by means of two electrodes in contact with the bathing solution and the cotyledon of a six-day-old plantlet. We varied the light intensity and wavelength, and worked with green and photobleached (SANDOZ 9789 pretreated) plants. Light intensities below 1.4 W m−22 of white light did not produce any appreciable transients, the amplitude of change of potential difference then increasing to a maximum ≈ 20 W m−2, where it stayed constant upto light intensities above 100 W m−2. A maximum in response was obtained at 644 nm and wavelengths>700 nm did not cause any transients. No transients could be observed with bleached or DCMU treated plants. Thus while the participation of the photosynthetic process in the light-induced transients is unequivocal, the participation of a phytochrome coupled component could not be ascertained.</div>","PeriodicalId":8798,"journal":{"name":"Biochemie und Physiologie der Pflanzen","volume":"188 4","pages":"Pages 211-219"},"PeriodicalIF":0.0,"publicationDate":"1992-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S0015-3796(11)80024-7","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90478159","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}

During a period of 24 h, methyl viologen induced a significant decrease of NADPH + H+ compared with the control, resulting in a marked decrease of ARC (anabolic reduction charge: [NADPH + H+]/[NADPH + H+ + NADP+]). Later on, the ARC of treated samples remained on a constant level at least until 72 h, though the total content of phosphorylated pyridine nucleotides decreased. The CRC (catabolic reduction charge: [NADH + H+]/[NADH + H+ + NAD+]) of treated seedlings was lowered only transiently. This indicates that reducing equivalents contribute to the detoxification of reactive oxygen species only initially during methyl viologen application. The decrease of functions — photosynthesis, respiration — supports the view that after prolonged treatment the progressive damage of cell components rather than the availability of reducing equivalents limits the capacity of the plant tissue to detoxify methyl viologen-induced reactive oxygen species.</div>","PeriodicalId":8798,"journal":{"name":"Biochemie und Physiologie der Pflanzen","volume":"188 4","pages":"Pages 231-240"},"PeriodicalIF":0.0,"publicationDate":"1992-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S0015-3796(11)80028-4","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81208539","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}
