Opis:
The usefulness of mutagenic treatment to enlarge isozymic variability of barley and the use of induced mutants for genetic analysis were evaluated. N-methyl-N-nitroso urea, sodium azide and gamma rays were employed as mutagenic agents. Electrophoretic assays of 3848 M₂ seedlings obtained by chemical mutagenic treatment of the spring barley cultivars Dema, Aramir, Bielik and 3100 M₂ seedlings obtained by physical mutagenic treatment of the cv. Dema revealed 70 isozymic mutants, which represent 30 separate mutants in 25 M₁ plants. Most of mutations (27) were induced by chemical mutagen at polymorphic esterase loci. The occurrence of induced mutants at monomorphic loci, Got2 and Lap2, made it possible to perform genetic analysis of those loci in barley including mapping respective genes within chromosomes.

Opis:
In the paper the detection of the SSCP polymorphism within the 5’ fragment of bovine beta-lactoglobulin (LGB) gene is described. The 5’ fragment of LGB gene (209 bp) was PCR-amplified and then subjected to electrophoresis allowing the detection of SSCP polymorphism. Among 124 animals (50 cows and 74 bulls) six SSCP patterns were identified and named Rl, R2, R3, R4, R5 and R6, which occured with the frequency of 0.32, 0.51, 0.09, 0.06, 0.01 and 0.01, respectively. The PCR-SSCP method is simple, fast, and relatively inexpensive. The SSCP polymorphism reported in the paper may be useful in looking for the associations between different SSCP patterns and LGB gene expression and milk properties.

Opis:
The present study describes a rapid, simple method of bovine IVF embryo sexing by use of PCR technique. A pair of primers corresponding to the bovine amelogenin sequence has been used. The Rapid Cycler (Idaho Technology, USA) used in the current experiment enabled the PCR programme consisting of 55 cycles to be completed in less than 40 minutes. Therefore the total sexing procedure could be performed in less than 90 minutes. The described method succeded in case of 85% analysed embryos.

Opis:
We have analysed allele distribution at the highly polymorphic variable number of tandem repeats (VNTR) locus D1S80 (pMCT118) in the Polish population using the, polymerase chain reaction (PCR) technique. Characteristics of the D1S80 locus makes it a very useful marker for population genetic research, genetic linkage studies and forensic identification of individuals. During our routine application of the D1S80 marker to paternity testing in several cases of homozygosity detected by polyacrylamide gel electrophoresis, heteroduplex formation for alleles 18 and 24 was also observed. Direct sequencing of PCR products revealed that alleles 18 and 24 of locus D1S80 actually represent a mixture composed of different sequences. Our observations indicate that identification of some 18 and 24 VNTR alleles based only on size estimated in electrophoretic analyses could lead to errors in paternity testing and DNA profiling.

Opis:
C-banding identified centromeric heterochromatin polymorphism, most often located in pair no. 16, was a basis for selecting animals for the experiment. The aim of the experiment was to assess the impact of centromeric heterochromatin polymorphism on pig fertility, expressed by litter size. The research included the first two litters obtained from 30 pairs of parents with different genotypes as regards the parameter under study. A statistical analysis of the number of offspring from different mating types showed no significant differences between the experimental groups of animals. The results obtained did not confirm suggested correlation between polymorphism of the centromeric heterochromatin regions and pig fertility, estimated by mean litter size. Thus the polymorphism cannot be regarded as a selection criterion.

Opis:
The effect of transferrin genotypes and genes and globulin antigens on sheep resistance/susceptibility to mastitis was analysed. The udder health condition was diagnosed on the basis of the somatic cell count in 1 ml of milk and results of bacteriological tests. It was found that sheep with the transferrin genotype AC, AD and CC were characterised by a better health of the mammary gland than the remaining ewes. Among 9 transferrin alleles observed in the examined sheep, only the presence of transferrin I allele in the ewes genotype was connected with the somatic cell count below the mean value of this trait. The presence of transferrin A allele in the sheep's genotype was connected with a small infection of milk with mastitis pathogens. The serum globulin antigens analysed did not significantly affect the somatic cell count in the milk of the examined ewes. However, the antigens A2, NS1 (antigens of ß-globulin) and GB2 (antigen of class IgG immunoglobulins) as well as the globulin antigen A6 and GA1 antigen of class IgG immunoglobulins showed to have a significant effect on the level of sheep milk infection.

Opis:
α-Amylase isozymes from rye endosperm were analysed by means of isoelectric focusing, polyacrylamide gel electrophoresis, immunoelectrophoresis and colorimetric assay. Α-AMY 1 (high pI) group was separated into 13 IEF bands, whereas in group α-AMY2 (low pI) 2 intensive and 6-8 faint bands were found. Two linked (2±1 cM) polymorphic loci and a single locus with two alleles encoding for α-AMY 1 and α-AMY 2 groups, respectively, were identified after genetic analysis of the IEF patterns. All α-amylase isozymes developed on PAGE, were shown to belong to α-AMY 1 group. It was demonstrated that a single PAGE isozyme corresponds to 2-4 separate IEF bands and that most of the IEF bands can be attributed to more than one PAGE isozyme. The activity of α-amylases from PAGE zone I was 2.3 times higher than the activity of zone II isozymes. A strong correlation between the activity and protein amount of particular α-AMY 1 isozymes (r=0.94) was found.
