On Antheridial Metabolism in the Fern Species Onoclea sensibilis L.
Dopp (1) demonstrated that the extract from mature prothalli of the fern species Ptcridiwtn1 aquiilinunil (L.) Kuhln hastened the onset of antheridium formation in young prothalli of this species by several days and in the prothalli of Dryopteris filixwwlas (L). Schott by several weeks. Dopp's conclusion that the prothalli of P. aquilinit elaborate a specific antheridium-inducing factor was con...
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
15 صفحه اولthe effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
Mutation Load in Natural Populations of the Sensitive Fern Onoclea Sensibilis Exposed to Soil Mutagens
This study examined mutations expressed in haploid fern gametophytes derived from spores collected in the wild in order to assay for the presence of mutagenic compounds in natural environments. Gametophytes of the fern Onoclea sensibilis were cultured from spores collected in 14 natural populations around the region of Montreal, Quebec, Canada. Most of the populations grew in soils exposed to s...
متن کاملBiochemistry of Fern Spore Germination: GLYOXYLATE AND GLYCOLATE CYCLE ACTIVITY IN ONOCLEA SENSIBILIS L.
In chlorophyll-containing spores of Onoclea sensibilis, depletion of lipid reserves during germination is correlated with increases in the activity of the glyoxylate cycle enzymes isocitrate lyase and malate synthase. In Onoclea, the heterotrophic activity associated with lipid catabolism occurs at the same time that autotrophic activity is taking place. Increases in chlorophyll content and in ...
