The effectiveness of this method was checked for aldolase, whose thermostability was established from the temperature required for 50% inactivation after heating for 30 min (T50%). Eggs from a relatively cryophilic species, the loach, were fertilized with sperm from warm-water aquarium fish: the danio, barb, rasbora, and goldfish. The T50% for aldolase from the hybrid embryos and fry was 1-4 degrees higher than for aldolase from the loach. The increase in T50% in the loach times danio and loach times rasbora hybrids was shown to be caused by functioning of the paternal aldolase-controlling genes, which began at the somite-formation stage and coincided with the increase in enzyme activity in the embryo. The value of T50% was increased to a greater extent and reached its maximum more rapidly in the somite tissues than in the cephalic tissues. A decrease in aldolase thermostability occurred in reciprocal danio times loach hybrids during the same developmental stages.</p>","PeriodicalId":76730,"journal":{"name":"The Soviet journal of developmental biology","volume":"5 3","pages":"220-8"},"PeriodicalIF":0.0,"publicationDate":"1975-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12303227","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}

It was shown that specific blocking of the photosynthetic reaction occurs in plastome mutants of A. majus; Photosystem II was found to be damaged in the en:alba-1 mutant and photo-system I was affected in the en:viridis-1 mutant. The plastid mutations in these mutants caused loss of certain soluble lamellar proteins and pigment--protein complexes or a reduction in their content, which led to disappearance of photosynthetic activity. When the content of high-molecular ribosomal RNA in the leaves of normal and mutant P. zonale plants was compared, the normal plants were found to have four types of RNA: two types of cytoplasmic-ribosome RNA and two types of plastid-ribosome RNA. No plastid-ribosome RNA was detected in the mutant. These results were confirmed by electron-microscopic examination: no ribosomes were detected in the mutant plastids. Thus, use of plastome mutants made it possible to establish that the genetic information concentrated in the plastid DNA controls formation of ribosomes and lamellae in the chloroplasts and thus affects chloroplast photosynthetic function.</p>","PeriodicalId":76730,"journal":{"name":"The Soviet journal of developmental biology","volume":"5 3","pages":"236-44"},"PeriodicalIF":0.0,"publicationDate":"1975-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12303229","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}
