[Allelic state of the molecular marker for the golden nematode (Globodera rostochiensis) resistance gene H1 among Ukrainian and world cultivars of potato (Solanum tuberosum ssp. tuberosum)].

The purpose of our investigation was determination of allelic state of the H1 resistance gene against the pathotypes Ro1 and Ro4 of golden potato cyst nematode (Globodera rostochiensis) among Ukrainian and world potato (Solanum tuberosum ssp. tuberosum) cultivars. The allelic condition of the TG689 marker was determined by PCR with DNA samples isolated from tubers of potato and primers, one pair of which flanks the allele-specific region and the other one was used for the control of DNA quality.

[Chemiluminescent determination of copper in the serum].

A procedure for chemiluminescent determination of copper in the blood serum ash is suggested using an indicator reaction between 4-aminophthalhydrazide and hydrogen peroxide permitting copper to be determined in a minimum (0.003 micrograms) concentrations in 1 ml of the blood serum.
