Description

A new primer set and a method for discriminating Korean beef using the same {A NEW PRIMER SET AND A METHOD OF SELECTING HANWOO BY USING THE SAID PRIMER SET}

The present invention relates to a novel primer set and a method for discriminating Korean beef using the same.

In recent years, the consumption of meat has increased as the Korean economy has been rapidly westernized along with the growth of the national economy and the increase of income. Beef demand has also increased. Meanwhile, as the beef market is fully opened, imported beef enters the domestic market indiscriminately, and imported beef, which is relatively cheaper than Korean beef, is quickly dominating the domestic beef market.

Domestic livestock farmers' response strategy is to differentiate them from imported beef through the production of high quality, high quality beef. The high quality of Korean beef has deepened the price gap between Korean beef and imported beef, and the price gap caused frequent cases of distributional irregularities in which cheap imported beef was sold as expensive Korean beef. For example, several cases related to the sale of mud-carps, such as the sale of mixed beef and imported meat with Hanwoo beef, were made at department stores and department stores, including Hanwoo meat gift sets.

The sale of bluffs has been pointed out as another cause of weakening the competitiveness of Hanwoo beef. In order to eradicate this, the government mandated a crackdown on the meat transaction record (the transaction history system). One reason for this is the lack of scientific and objectively secured beef and imported beef. In other words, the development of the technology for distinguishing Korean beef from cows, imported beef and imported beef is essential to block the sale of bovine meat and protect the Korean beef cattle farmers and beef market. On the other hand, it is common to distinguish breeds of cows such as hair color, body shape, etc., which are external characteristics. Therefore, breeding is virtually impossible in cattle that have been slaughtered and converted to meat.

Recently, with the development of molecular biology and genetic analysis, homologous breed discrimination techniques using DNA sequence differences have been proposed. These discrimination techniques are based on DNA polymorphism, and specific examples include Restriction Fragment Length Polymorphism (RFLP), Amplified Fragment Length Polymorphism (AFLP), Single Strand Conformational Polymorphism (SSCP), Discrimination techniques include DAF, Decay Accelerating Factor, Microsatellite, Random Amplified Polymorphic DNA (RAPD), and Sequence Characterized Amplified Regions (SCAR) primers that extend some of the base sequences of RAPD primers.

However, these discrimination techniques also have problems as a practical method for discriminating Korean beef. As a specific example, among the above-described identification techniques, Korean beef cattle discrimination method (Byeong-rok Min, Lee Mu-ha, Han Jae-yong, Beef varieties (Korean beef, beefstein (Holstein), imported beef) using RAPD), Korean Society for Animal Science Vol. 37 (6) ): 651-660 (1995)) has a problem in that it is difficult to put to practical use because of the low reproducibility and accuracy of the results due to the sensitivity of PCR amplification conditions.

In addition, Hanwoo discrimination method using Hanwoo specific SCAR primer that partially extended the base sequence of RAPD primer (Hong Young Ho, Jung Il Jung, Kim Tae Heon, Kim Heebal, Yoon Do Hak, Kim Hyung Sun, Cho Byung Wook, Han Jae Yong, Han Soong Yong, Marker specificity using breed specificity Factor Development, Vol. 2 (2): 107-114 (1998), was found to be relatively stable compared to the RAPD method, but this problem was also pointed out in the reliability of discrimination.

Recently, discrimination techniques using the MC1R (Melanocortin 1 Receptor) gene, which is known to be involved in the dark and red color expression, have been proposed.

Specific examples include the method of discriminating Hanwoo cattle using PCR-RFLP using three restriction enzymes such as Bse118Ⅰ, MspⅠ and Aci I (Kim Tae-heon, Yoon Doo-hak, Park Eung-woo, Lee Hye-young, Oh Sung-jong, Jung Il-jeong, Tak Tae-young, Kim Kyung-nam, Han Jae-yong, and Cattle Breeds by Melanocortin Receptor 1 A Study on Genotype Frequency of (MC1R) Gene, Journal of Animal Science and Technology Vol. 42 (6): 735-744 (2000)) and PCR-RFLP Methods Using Two Restriction Enzymes, BsrFⅠ and MspⅡ , Han Sang, Korean Beef Determination using PCR-RFLP marker of MC1R, the Korean Society of Animal Science and Technology Vol 42: 379-390 (2000)).

The method of discriminating Hanwoo beef using the MC1R gene is very efficient and economical in distinguishing Hanwoo beef from cow meat (Holstein species) and some imported meat products (Black Angus species). There is a problem in that it is not possible to distinguish between the limousine species having a similar color to Korean beef, the simanthal species having a light yellowish brown color to the deep reddish brown color, or the hybrids of Hanwoo and cows (Holstein).

The present invention, as described above, solves the problems of the existing method of discriminating Korean beef and imported meat, to provide a novel primer set and a method for discriminating Korean beef using the same for quickly and accurately discriminating various kinds of imported beef and Korean beef For the purpose of

In order to achieve the above object, the present invention provides a set of primers for screening Hanwoo.

In addition, the present invention provides a method for discriminating Hanwoo beef and Hanwoo beef using the Hanwoo beef screening primer set.

The present inventors compared and analyzed the DNA sequence of a domestic cow and the DNA sequence of a foreign cow, and as a result, a primer capable of identifying and searching for an indel, insertion and deletion region and a mismatch region existing in a domestic cattle. The present invention was completed by manufacturing a set and using the same to develop a method for discriminating meat of Korean cattle and foreign beef.

Hereinafter, the present invention will be described in detail.

In addition, as shown in FIG. 14, using the primer YUHW-MBL-7 (primer set 5), PCR was performed under the conditions of Table 2, and the number of individuals whose DNA bands of sizes other than 286 base pairs appeared was Hanwoo. 12 were cows, 5 were foreign cows, and 3 were cows. In addition, as shown in Table 4, 91 of the 179 samples in the case of Hanwoo, that is, 51%, while in foreign cattle, only 12 of the 80 samples, that is, only 18%, a plurality of bands appeared.

Based on the above results, when PCR was performed using the primer YUHW-MBL-7, a sample showing a plurality of bands (ie, bands different from the primer size) was meat of foreign beef, that is, Korean beef rather than imported meat. The probability was confirmed to be high.

In addition, as shown in FIG. 15, using PCR YUHW-MBL-8 (primer set 6), PCR was performed under the conditions of Table 2, and the number of individuals whose DNA bands of sizes other than 287 base pairs appeared was Hanwoo. 6 were cows, 4 foreign cows and 0 cows. In addition, as shown in Table 4, only 51 of the 179 samples, that is, 29% in the case of Hanwoo cattle, while only 5 of the 80 samples, 6% of the 80 samples in foreign cattle appeared a plurality of bands.

Referring to the results of the above experiment, using the indel, insertion and deletion (Indel, Deletion) region of the native cow's own genetic markers, to make a primer set that can detect this, using PCR and electrophoresis after using By analyzing the differences in the DNA band patterns of electrophoresis, the present invention distinguishes between Korean cattle and foreign cows, compared to conventional methods using the MC1R (Melanocortin 1 Receptor) gene, which is known to be involved in groping. In a short time, it is possible to distinguish between Korean beef and imported meat in a simple way.

In addition, it was confirmed from the experimental results that the insertion-deletion (Indel, insertion and deletion) region of the Korean cattle can be recognized as a gene marker unique to Hanwoo, oligo having a nucleotide sequence including the insertion-deletion region of the Hanwoo It is expected that the probe nucleotide oligonucleotide (probe) can be used to effectively distinguish between Korean beef and imported meat.
