TEST OF INTERACTION BETWEEN GENETIC MARKERS THAT AFFECT FITNESS IN ASPERGILLUS NIGER
TLDR
The results suggest that the marker mutations have independent effects on fitness, and hence they do not support the deterministic mutation hypothesis of the evolution of sex. Expand
Chemical structure of algaenans from the fresh water algae Tetraedron minimum, Scenedesmus communis and Pediastrum boryanum
Abstract The cell walls of the fresh water green microalgae Tetraedron minimum, Scenedesmus communis and Pediastrum boryanum are composed of highly resistant, non-hydrolyzable aliphatic biopolymersExpand
A comparative study of fossil- and extant algaenans using ruthenium tetroxide degradation
In this study the chemical structure of algaenans isolated from the freshwater algae Tetraedron minimum, Pediastrum boryanum and Botryococcus braunii are compared with their fossil counterparts byExpand
Molecular and functional characterization of the non-isopeptide-selective ETB receptor in endothelial cells. Receptor coupling to nitric oxide synthase.
TLDR
It is demonstrated that the ETB receptor is functionally coupled to NOS and coordinates the generation of NO via a tyrosine kinase-dependent and a calcium/calmodulin-dependent pathway. Expand
Thrombin Induces the Activation of Progelatinase A in Vascular Endothelial Cells
TLDR
These data demonstrate that endothelial cells express a novel activation mechanism for progelatinase A, proteolytically active thrombin regulates this activation mechanism, and activation occurs independently of the functional throm bin receptor. Expand
Cell wall glucomannoproteins of Saccharomyces cerevisiae mnn9
TLDR
Mannoproteins were isolated from Saccharomyces cerevisiae mnn9 mutant cell walls by laminarinase digestion and purified by affinity and anion‐exchange chromatography to find three predominant proteins with molecular masses of 300 kDa, 220 kDa and 160 kDa. Expand
Ethanol stimulates phospholipid turnover and inositol 1,4,5-trisphosphate production in Chlamydomonas eugametos gametes
TLDR
From the effect of ethanol on the 32P-labelling of polyphosphoinositides, it is concluded that the synthesis of these lipids is stimulated, and this effect, coupled to a rise in intracellular calcium concentration, could explain gamete activation. Expand
Chemical fingerprinting of algaenans using RuO4 degradation
The freshwater green microalgae, Oocystus solitaria Wittrock f. maior Wille, Pediastrum braunii Wartmann, Pediastrum kawraiskyi Schmidle, Sorastrum spinulosum Nageli and Coelastrum reticulatumExpand
The Hyphal Wall of Mucor mucedo
Treatment of isolated hyphal walls of Mucor mucedo with nitrous acid resulted in the release of two water-soluble polyanions: (a) a glycuronan, containing all the neutral sugars and uronic acidExpand
Relationship Between Sexuality and Carotene Synthesis in Blakeslea trispora
TLDR
From spectroscopic analysis of purified samples, it appears that the hormones are identical with trisporic acids B and C, evidence for the hypothesis that the sex hormones are produced by B. trispora-plus only. Expand
