Definitions
- the invention relates to a genetic marker at the 5 'end of the ⁇ S1-casein gene (CSN1S1) and the Kaseingen complex and a method for age and lactation-independent typing of cattle by determining the allelic state in this area, and the use of this method for selection of organisms with a preferred allele, for example in marker-based selection.
- CSN1S1 ⁇ S1-casein gene
- the heredity potential (with regard to the milk protein content and other breeding-relevant characteristics) of breeding animals is currently estimated using the breeding value estimation based on test pairs and performance recording of the offspring.
- the disadvantage of this conventional method is obvious: in cattle, it takes about 3 years between the first insemination with a test bull and the onset of lactation by the first daughters, or about 4 years until the daughter is completely lactated. Only then can the breeding value be estimated. Until then, keeping the bulls until the first estimated breeding values and test pairs are available will result in costs that are significant over this long period and in the sum of the animals. This applies analogously to the recording of own work and the determination of a breeding value for cows.
- lactalbumin sequence for the selection of breeding animals is disclosed in EP0555435.
- Numerous genetic tests also exist for the bovine ⁇ -casein (Denicourt et al., 1990, Animal Genetics 21, 215-216; Medrano & Aguilar-Cordova, 1990, Biotechnology 8, 144-145; Pinder et al., 1991, Animal Genetics 22, 11-20; Schlee & Rottmann, 1992, J Animal Breed. Genet. 109, 153-155; Zadworny & Kuhnlein, 1990, Theor. Appl. Genet. 80, 631-634) because of this Protein influences on the processing properties and cheese suitability of milk are attributed (see Lodes et al., 1996, Milchwissenschaft 51, 368-373 and 543-548).
- the promoters of the bovine milk protein genes and those of the ⁇ s1-casein gene are also used in the creation of transgenic animals and for expression in cell cultures.
- DE 38 54 555 T2 the disclosure content of which is included here, describes the use of the ⁇ s1-casein promoter and the signal peptide for the production of recombinant proteins in the milk of mammals.
- Rudolph (1999, Trends in Biotechnology (TIBTECH) 17, 367-374) also provides an overview of the use of transgenic animals for the production of recombinant proteins and the promoters used for this.
- microsatellite markers which were determined in QTL analyzes, are only suitable to a limited extent for use in marker-based selection, since the respective marker-QTL coupling must first be clarified. These are Microsatellite markers in each case for indirect tests which, depending on the density of the coupling to the causative gene location, have a reduced reliability of information.
- the disadvantage of the process of EP 0555435 is that lactalbumin makes up only a small (approx. 2-5%) portion of the total milk protein.
- the casein ( ⁇ s1-, ⁇ s2-, ß- and ⁇ -casein) represent the largest share with around 80% of the total protein. Therefore, only a little breeding progress can be expected when using this selection marker.
- the genetic test for DGAT1 by Winter et al. has the disadvantage that from the point of view of breeders and milk producers, the fat content of milk is not of primary interest, but is secondary to protein content.
- the disadvantage of the Koczan et al. (1993, Animal Genetics 24, 74) consists in the fact that on the one hand the reliability of the differentiation between the variants ⁇ s1-casein B and C (for which the test was developed) has now been refuted, and on the other hand the method has only one position the base substitution is detectable and further mutations in this area are not taken into account.
- the object of the invention is therefore to provide a genetic marker and a method for typing on milk performance characteristics in order to examine animals for milk performance characteristics regardless of age and lactation on the basis of their genetic material.
- the problem is solved by providing a genetic marker that is also polymorphic in selected milk breeds in the ⁇ s1-casein gene region and a method that enables the animals to be typed regardless of age and lactation, the genetic mapping of the s1-casein gene, and the investigation of closely linked genes or directly caused effects and a breeding use.
- the method according to the invention is a genetic test for a functional gene segment, the reliability of the information is greater than with coupled markers and the test result is available within a few days to hours.
- This test can also be used to select breeding animals which are more likely to have positive inheritance properties, so that the number of test pairs and animals to be tested can be reduced, which can reduce the considerable cost of the test pairs.
- the method according to the invention thus eliminates the disadvantages described in the prior art.
- the invention consists of a test kit which contains the oligonucleotides for enriching a partial region of the marker sequence of the ⁇ s1-casein gene, preferably the primer 1 CSN1S1 pro1f (5 'GAA TGA ATG AAC TAG TTA CC 3'), primer 2 CSN1 S1 prol r (5 'GAA GAA GCA GCA AGC TGG 3') and primer 3 CSN1S1 pro2r (5 'CCT TGA AAT ATT CTA CCA G 3') as well as reference samples for one or more sequences of the marker sequence of the ⁇ s1-casein gene and its alleles contains.
- the primer 1 CSN1S1 pro1f 5 'GAA TGA ATG AAC TAG TTA CC 3'
- primer 2 CSN1 S1 prol r 5 'GAA GAA GCA GCA AGC TGG 3'
- primer 3 CSN1S1 pro2r 5 'CCT TGA AAT ATT CTA C
- the examined sequence section which is delimited by the oligonucleotides CSN1 S1 prolf and CSN1S1pro1 r or CSN1 S1 pro2r (gray box in Figure 1) within the German Holstein breed has four alleles which can be detected by means of a single-strand conformation polymorphism analysis and is therefore sufficiently polymorphic to carry out a genetic mapping and analysis of the effect of the alleles on milk production parameters.
- the polymorphism found is thus located in a presumably functional gene region and is thus a suitable marker for milk performance characteristics, in particular for the protein content.
- the sequence section is flanked with the following oligonucleotide sequences according to the invention, which are used as primers for amplification by means of PCR, the combinations of primer 1 with primer 2 and primer 1 with primer 3 being possible:
- Primer 1 CSN1 S1 prolf (5 'GAA TGA ATG AAC TAG TTA CC 3')
- Primer 2 CSN1 S1 prol r (5 'GAA GAA GCA GCA AGC TGG 3')
- Primer 3 CSN1S1 pro2r (5 'CCT TGA AAT ATT CTA CCA G 3 ')
- the primer binding sites are highlighted in gray in Figure 1.
- a method according to the invention is provided which can be carried out directly on the genetic material of the organism to be examined.
- a genetic mapping of the ⁇ s1-casein gene within the coupling map is made possible and the determination of the allelic state in individual organisms, e.g. Cattle, which determines the genetic potential with regard to milk protein content within a few hours.
- the organism is by definition an animal, in particular a mammal, in particular a cattle, a sheep or a goat including embryos of this species.
- the organism is also a genetically modified organism (GMO), which contains the sequence section described from the ⁇ s1-casein gene and the 5'-flanking region ( Figure 1) or parts thereof.
- GMO genetically modified organism
- the genetic material is by definition genomic DNA or RNA from animals, but also plasmid DNA from bacteria, from artificial chromosomes such as BACs and YACs or constructs made of genetic material from various organisms, e.g. for the production of transgenes.
- the starting material for obtaining DNA- or RNA-containing material is, for example, blood, leukocytes, tissue including biopsy material, milk, sperm, hair, individual cells including cell material from embryos, a bacterial culture or also isolated chromosomes. Furthermore, amplifi- decorated genetic material, which contains the marker sequence (Figure 1) or parts thereof, again starting material.
- the genetic material is isolated using standard methods, e.g. in the manual "Molecular Cloning” (Sambrook, Fritsch, Maniatis, 1989; Cold Spring Harbor Laboratory Press, New York) or can be carried out using commercially available kits (e.g. Nucleospin, Machery Nagel, Düren, Germany).
- the enrichment is preferably carried out by means of a polymerase chain reaction (PCR, Mullis & Falloona, 1987, Methods in Enzymology 155, 335-350), it also being possible to use fluorescent-labeled, radioactive or chemically labeled primers. If RNA is used as the genetic material, a previous reverse transcription is expediently carried out (Myers & Gelfand 1991, Biochemistry 30, 7661-7666).
- sequence section is preferably enriched with the following oligonucleotide sequences according to the invention as primers for the amplification, the combinations primer 1 with primer 2 and primer 1 with primer 3 being possible:
- CSN1 S1 prolf and CSN1S1 pro1 r is limited.
- a number of standard techniques known to those skilled in the art are available for determining the allelic state, such as the sequencing according to Sanger et al. 1977, the method of pyrosequencing (www.pyrosequencing.com), by displaying single-stranded conformational polymorphisms (SSCP, Orita et al. 1989, Genomics 5, 874-879), using restriction fragment length polymorphisms (RFLP; Botstein et al. 1980, American Journal of Human Genetics 32, 314-331) and PCR-RFLP (Damiani et al.
- the primers according to the invention with a label (fluorescence, radioactivity and the like) and to carry out the determination of the allelic state on the automatic sequencer, by autoradiography or chemiluminescence. If unlabeled primers are used, the allelic state is determined by displaying the fragments after gel electrophoresis by staining the nucleic acids, e.g. with ethidium bromide (Sambrook et al., 1989) or in the silver staining method (Bassam et al 1991, Analytical Biochemistry 196, 80-83).
- allelic state is to be understood as the presence of a certain nucleotide sequence within the enriched area.
- Figure 2 shows an example of the nucleic acid sequence of four different allelic states of the marker according to the invention ( Figure 2, alleles 1, 2, 3 and 4).
- allelic states by means of single strand conformation polymorphisms (SSCP) is particularly advantageous, since the allelic state can be read off directly from the fragment pattern.
- the method also enables the detection of further mutations not described here. For this reason it is particularly well suited for the analysis of the homologous genome area in animal species other than cattle.
- the use of a shorter fragment for example the sequence marked with an arrow in FIG. 1 and determined by the oligonucleotides according to the invention, is recommended as the complete sequence.
- Figure 4 shows a schematic representation of alleles 1 to 4 of the marker CSN1S1 in the SSCP analysis in 12% acrylamide: bisacrlymide 49: 1 gel with 1% glycerol addition.
- Fields 1 to 4 represent the four different separation patterns of the alleles. The direction of migration of the molecules in the electric field from cathode (-) to anode (+) is shown with an arrow.
- the single strands of the alleles show a typical, clearly different separation pattern. Since both DNA single strands are represented by silver staining, each of the alleles is characterized by two bands.
- allelic state 1 or 4 which differs from allele 2 by the number of potential binding sites for transcription factors.
- oligonucleotide sequences according to the invention are used as primers to carry out the amplification of the marker by means of a PCR reaction: Primer 1 CSN1S1 prolf (5 'GAA TGA ATG AAC TAG TTA CC 3')
- the reaction mixtures each contain 20-100 ng of genomic DNA to be tested in 15 ⁇ l, 10pmol of each oligonucleotide CSN1S1 prolf and CSN1S1pro1 r, 0.5 U Taq DNA polymerase (Peqlab Biotechnologie, Er GmbH), 50 ⁇ M dNTPs in a standard buffer (10mM Tris HCl pH 8.8, 50 mM KCI, 1.5 mM MgCl 2 ).
- the temperature program (in a thermal cycler model iCycler from Biorad) is selected as follows: 1 min. - 93 ° C (1x), (40 sec - 91 ° C, 40 sec. 57 ° C, 40 sec - 70 ° C) (30x) and 3 min - 70 ° C (1x). This was followed by cooling to 4 ° C.
- 25 ⁇ l of a formamide denaturation buffer are then added to each reaction mixture (95% formamide, 0.025% (w / v) bromophenol blue, 0.025% (w / v) xylene cyanole (FF), 20 mM EDTA), the mixture for 2 min at 93 ° C heated, cooled in ice water and each 4 ⁇ l of the mixture loaded on a 12% 49: 1 acrylamide bisacrlymide gel with 1% glycerol addition. The separation takes place over 20 hours at 420V and 10 ° C in a vertical electrophoresis chamber model Pengiun P9DS (OWL Scientific, Woburn, USA) with a 0.8 mm thin 16x16cm gel.
- Pengiun P9DS OWL Scientific, Woburn, USA
- DNA is isolated from blood samples from 503 cows of the German Holstein breed using the method of Mongomery & Sise (1990, NZ J Agric Res 33, 437-441).
- the sequence shown in FIG. 2 is enriched with the oligonucleotides CSN1S1 prolf and CSN1 S1pro1 r according to the invention, as described above, and the variations present are represented by SSCP technology.
- all four alleles are also detectable. The following allele frequencies are determined:
- Allele 3 - 0.194 Allele 4 - 0.036 Allele 2 is the most common allele in the German Holstein breed, followed by allele 3 and the two rare alleles 1 and 4.
- the frequency of the genotypes is 22> 23> 24> 12> 33> 34. Genotypes 11 and 14 and the combination of these two rare alleles (genotype 14) are not found in the cows examined.
- the ongoing FLIPS analysis leads to the final mapping of CSN1S1 between the markers FBN14 and CSN3.
- the total length of the coupling map of BTA6 calculated with the 11 markers in the 8 families is 161.1 cM.
- the following table 1 shows the position of all markers included in the coupling map and the comparative information from the existing gene maps MARC97 and IBRP97.
- Table 2 The breeding values of the bulls are estimated centrally by the United Information Systems for Animal Husbandry (VIT) in Verden. A total of over 150,000 daughters and their performance data are included in the breeding value estimation. All bulls use deregistered breeding values for milk quantity, protein and fat quantity, protein content (in%) and fat content (in%) in the variance component estimation. The breeding values are deregression as in Thomsen et al. (2001, J Anim Breed Genet. 118, 357-370).
- the variance component estimation is carried out with the program package SAS.
- the marker CSN1S1 is first taken into account in the model, since other influencing factors (e.g. operational effects, milking frequency) are already corrected as part of the breeding value estimation.
- the analysis shows significant effects of the marker CSN1S1 on all traits examined (deregressed breeding values for protein content (DRG_PP), milk quantity (DRG_MY1), fat quantity (DRG_FY1), protein quantity (DRG_PY1), fat content (DRG_FP)).
- Table 3 shows the effect of CSN1S1 on deregistered breeding values for milk performance characteristics with indication of the error probabilities (p) for the effects on the individual characteristics.
- the greatest significance is calculated for the effect on DRG_PP. Since the investigated marker CSN1S1 lies directly in the regulatory region of a milk protein gene, this could be an indication of a direct effect.
- the marker CSN1S1 fulfills the requirements for a functional candidate gene.
- Genomic DNA from various European sheep breeds (milk and meat sheep) is used as a template for the amplification of the CSN1S1-5 'region as described above and an SSCP analysis is carried out, whereby 5 different migration patterns occur which are very similar to the migration pattern of DNA from cattle (Data not shown).
