Two maturation media with high and low concentration of gellan gum were used to evaluate the maturation performances of four maritime pine ESM (embryonal-suspensor mass) lines. The maturation performance is influenced by sampling modalities; the oute

In solutions of CuCl2 and adenine copper can be bound to adenine. Two Cu(adenine)(2) complexes [Cu(C(5)H(5)N(5))(2)]2+/Cu(C(5)H(4)N(5))(2)] are in equilibrium with free adenine. Copper-adenine complexes present a catalytic activity (e.g., H(2)O(2) di

Etiolated cells of Euglena gracilis, grown at 26°C in the dark, were taken at different growth phases and submitted to heat shocks (up to 2 hr) at temperatures ranging from 33 to 42°C. Their volumes and mortality increased rapidly with temperature

Mutations conferring herbicide resistance have been detected in two new strains (ZR250 and ZR480) of Euglena gracilis Z by partial gene cloning and sequencing. These mutants were originally derived from Z cells grown in medium containing progressivel

The lipid class and fatty acid compositions of Euglena gracilis were analysed after growth under various conditions of autotrophy or photoheterotrophy, in order to identify the contribution of lactate (a carbon source) and ammonium phosphate (a nitro

Summary A study of the action of DNP on the respiration of Euglena gracilis (Z Klebs strain) treated or untreated with antimycin shows that the generation time of cells increases proportionally to DNP concentration from 10 -6 to 10 -5 M, with a furth

Xeroderma pigmentosum (XP) and trichothiodystrophy (TTD) are two recessively transmitted human diseases characterized by DNA repair deficiency. While XP is associated with a very high incidence of cancer on skin exposed to sunlight, TTD is not a canc

Euglena gracilis can be used as a microbial model to study the effect of drugs on lactate metabolism and gluconeogenetic synthesis. The cell growth and metabolism have been characterized in a 33 mM lactate medium, non-supplemented or supplemented by

We report that an internal and non-UV-dependent type of neoplasia, the human cervical intraepithelial neoplasia (SIL), is also deficient in catalase activity, like the UV-induced tumors in the autosomal recessive human epithelial disease, xeroderma p
