Formation of Large Thioredoxin / Accompanies Chloroplast Development in Scenedesmus obliquus
Chloroplast-free mutant cells C-2A ' of the green algae Scenedesmus obliquus lack thioredoxin / , which functions in the light activation of chloroplast enzymes, but do con tain the regular thioredoxins I and II. When dark-grown algae are transferred to light, thioredoxin / activity appears rapidly and increases in parallel with photosynthetic ac tivities; however it precedes chlorophyll bios...
متن کاملTransfer ribonucleic acid from Scenedesmus obliquus D3.
Scenedesmus obliquus is a green alga whose cells have a well-defined nucleus, and contain a chloroplast. Even when grown in the dark these cells retain their chloroplast. Because of the toughness of the cell wall, extraction of tRNA requires either vigorous homogenization of the cells before phenol extraction or prolonged phenol extraction at 60°C. Determination of the amount of tRNA and its pu...
متن کاملThe nucleotide sequence of 5S rRNA from Scenedesmus obliquus.
The nucleotide sequence of the cytoplasmic 5S ribosomal RNA from Scenedesmusobliquus has been determined using post-labelling techniques. The sequence is closely related to the 5S RNA sequence of Chlorella and contains all the areas of invariant sequence which appear to be conserved in plant cytoplasmic 5S RNA species.
متن کامل“Rational” Management of Dichlorophenols Biodegradation by the Microalga Scenedesmus obliquus
The microalga Scenedesmus obliquus exhibited the ability to biodegrade dichlorophenols (dcps) under specific autotrophic and mixotrophic conditions. According to their biodegradability, the dichlorophenols used can be separated into three distinct groups. Group I (2,4-dcp and 2,6 dcp - no meta-substitution) consisted of quite easily degraded dichlorophenols, since both chloride substituents are...
متن کاملColony formation in Scenedesmus: grazer-mediated release and chemical features of the infochemical
In the unicellularly growing green alga Scenedesmus acutus, the formation of many-celled coenobia may be induced by an infochemical released by the grazer Daphnia magna. We used a standardized bioassay to obtain information about the release of the infochemical by actively feeding D.magna and its chemical nature. The infochemical could not be extracted from the alga or the grazer by aqueous or ...
