The RIB7 gene encoding the enzyme of the final stage of riboflavin biosynthesis in Pichia guilliermondii--riboflavin synthase was cloned on the pFL38 shuttle vector as the Sau3A fragment of the chromosomal DNA of about 4 kb. The HindIII fragment of 1.4 kb was subcloned from the hybrid plasmid pFR7 obtained onto the pUC18 plasmid.

Inactivation of the gene in Hansenula polymorpha strain 48V, as well as Leu(-)-Leu+ conversion of phenotype and arising of antibiotic G418 resistance resulted from transformation of the strain by the linear DNA molecules of the cloned HIS-gene with the in vitro inserted LEU2 gene from Saccharomices cerevisiae and KmR gene. The Southern hybridization analysis of the Leuf+His- G418R clones representing 1-2% of transformants population together with the DNA analysis of the monospore clones from the hybrid Leu+His-G418R transformant tetrad and tester strain have revealed the locus specific nature of the clones.

It should be mentioned that despite the fact that the given parameter is not so far generally acknowledged, it reflects accurately enough the operation "reliability" of the automated system. The author bases theoretically the choice of the adaptive piecewise model of ECS.

EcoRI fragment of 4 kb with RIB1 gene was subcloned from the pFRI hybrid plasmid obtained into the pUC18 plasmid and then shortened to give 2.9 kb via deletion in SalGI site.
