Grazer-induced morphological defense in Scenedesmus obliquus is affected by competition against Microcystis aeruginosa
The green alga Scenedesmus is known for its phenotypic plasticity in response to grazing risk. However, the benefits of colony formation induced by infochemicals from zooplankton should come with costs. That is, a tradeoff in benefit-to-cost ratios is likely under complex environmental conditions. In this study, we hypothesized that the coexistence of Scenedesmus and its competitors decreases t...
متن کاملDaphnia growth on microcystin-producing and microcystin-free Microcystis aeruginosa in different mixtures with the green alga Scenedesmus obliquus
The hypothesis that negative effects of Microcystis on Daphnia growth and reproduction can be explained from the presence of microcystin in the Microcystis cells was tested by comparing the effects on Daphnia life history characteristics of a microcystin-free mutant strain and microcystin-containing strain of the cyanobacterium Microcystis aeruginosa PCC7806. To avoid nutritional deficiency, Mi...
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 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 کاملFormation 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...
