It has been shown that plant mitochondria have a translocase similar to the adenine-nucleotide translocase of animal mitochondria, since atractyloside, at a concentration of 40 micro M, inhibits Chance's State 3 respiration 100%. It has been demonstrated that palmitoyl-CoA--formed by a mitochondrial system for activation of fatty acids--lowers the rate of State 3 respiration during succinate oxidation, if palmitate, CoA and ATP are introduced into the incubation medium simultaneously. This can be explained by an inhibition of transport of adenine nucleotides through the internal mitochondrial membrane. The inhibition in question is counteracted by addition of carnitine.</p>","PeriodicalId":9166,"journal":{"name":"Biology bulletin of the Academy of Sciences of the USSR","volume":"6 4","pages":"499-501"},"PeriodicalIF":0.0,"publicationDate":"1979-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"11447514","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}

Life forms of plants are divided into thirteen types corresponding to the nature of their basic metameres. Further, every type is divided into subtypes and sections according to the character of these metameres and then into smaller grades (classification units of the system of living forms corresponding to one trait and its evolutionary level) according to categories of traits: ramification, vegetative flexibility, rate of changes of metameres, types of habitat and environment. On the basis of the principle of parallel divergence scales of traits were constructed for each category. Corresponding to 26 paires of alternative traits 26 degrees of hierarchic classification were devised and within the limits of every type of life form there were 2(26) grades at the lowest rank. Separate systems were developed for single-celled and colonial forms.</p>","PeriodicalId":9166,"journal":{"name":"Biology bulletin of the Academy of Sciences of the USSR","volume":"6 4","pages":"476-86"},"PeriodicalIF":0.0,"publicationDate":"1979-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"11753446","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}
