본 결과물은 농림축산식품부 GoldenSeed프로젝트 사업 및 과학기술정보통신부 개인기초연구 사업의 지원을 받아 연구되었습니다 (과제번호 213006055SBK30 및 2021R1A2C3006061).This result was researched with the support of the GoldenSeed Project of the Ministry of Agriculture, Food and Rural Affairs and the Personal Basic Research Project of the Ministry of Science and ICT (Task Nos. 213006055SBK30 and 2021R1A2C3006061).
무(Raphanus sativus L.)는 배추에 이어 국내 채소 종자 시장(약 2,000억)에서 두 번째로 중요한 채소 작물이며, 중국, 인도를 비롯한 아시아 국가에서 널리 소비되고 있다. 그러나 소비량이 많은 채소 작물임에도 불구하고 무는 유전체 정보에 기반한 분자 육종 기술 수준은 타 대표작물에 비하여 낮은 편이다.Radish ( Raphanus sativus L.) is the second most important vegetable crop in the domestic vegetable seed market (approximately 200 billion won) after Chinese cabbage, and is widely consumed in Asian countries including China and India. However, despite being a vegetable crop with high consumption, radish has a lower level of molecular breeding technology based on genetic information than other representative crops.
수확된 무를 잘랐을 때 속이 푸석푸석하고 빈공간이 생긴 경우를 종종 발견할 수 있는데, 이러한 현상을 바람들이(pithiness 또는 sponginess)라고 한다. 바람들이가 일어난 무는 상품적 가치가 없어 재배농가 소득에 큰 피해를 일으킬 수 있기 때문에, 무 육종가들은 바람들이가 일어나지 않는 무 품종을 개발하려는 노력을 기울여 왔다. 그럼에도 불구하고, 바람들이는 재배 환경과 유전적 요인이 복합적으로 작용하여 일어나는 특성이고 수확하여 뿌리를 절단해야 발생 여부를 확인이 가능하기 때문에 육종 과정에서 선별하여 배제시키기에 매우 어려운 특성으로 알려져 있다.When harvested radish is cut, it is often found that the inside is crumbly and empty spaces are formed. This phenomenon is called pithiness or sponginess. Radish breeders have made efforts to develop radish varieties that do not wind up because wind-infested radish has no commercial value and can cause great damage to growers' income. Nevertheless, it is known as a very difficult characteristic to select and exclude in the breeding process because it is a characteristic that is caused by a combination of the cultivation environment and genetic factors, and it is possible to check whether it occurs only by harvesting and cutting the roots.

However, the following examples are only to illustrate the present invention, and the content of the present invention is not limited to the following examples.

1.1 바람들이에 약한 무 원교10040호(WK40)의 전사체 분석1.1 Transcriptome analysis of Wongyo 10040 (WK40), which is weak to wind
원교10040호를 국립원예특작과학원의 노지(field grown)와 서울대학교 생명과학부 온실(greenhouse grown)에서 키우면서 파종 후 6주부터 10주 사이에 무 뿌리에 바람들이가 일어났는지의 여부를 microCT scanning을 이용하여 분석하고, 해당 뿌리로부터 총 RNA를 분리하였다. 분리한 총 RNA를 마크로젠에 의뢰하여 Illumina paired-end RNA sequencing한 결과, 총 17개의 무 개체로부터 4억 7천 7백 만개의 paired-end read들을 확보하였고, 이를 50,032개의 무 유전자 코딩 시퀀스에 mapping하였다. Differentially Expressed Gene (DEG; false discovery rate, FDR,≤0.05; |Fold Change|≥2)에 해당하는 3,966개의 유전자를 발견하였고 이들의 발현 양상과 기능을 K-means clusterning과 gene ontology (GO) term enrichment 분석(FDR ≤0.05)을 통해 유추하였다.While Wongyo No. 10040 was grown in the field grown of the National Institute of Horticultural and Herbal Science and in the greenhouse grown of the Department of Life Sciences, Seoul National University, microCT scanning was used to determine whether wind blowing occurred to the radish roots between 6 and 10 weeks after sowing. and analyzed, and total RNA was isolated from the root. As a result of Illumina paired-end RNA sequencing by commissioning the isolated total RNA to Macrogen, 477 million paired-end reads were obtained from a total of 17 radish individuals, which were mapped to 50,032 radish gene coding sequences. . 3,966 genes corresponding to Differentially Expressed Genes (DEG; false discovery rate, FDR,≤0.05; |Fold Change|≥2) were discovered, and their expression patterns and functions were analyzed by K-means clusterning and gene ontology (GO) term enrichment Inferred through analysis (FDR ≤0.05).
도 1a는 3,966개의 DEG를 발현 양상에 따라 K-means clustering 한 결과이며, 도 1b는 이렇게 분류한 두 cluster 구성 유전자에 대하여 GO term enrichment 분석한 결과이다. Cluster 1은 노지에서 자란 무에서 발현이 증가하며 이 가운데 특히 바람들이를 보여주는 개체에서의 발현이 더 증가하는 양상을 보여준다. Cluster 1을 구성하는 2,107개의 유전자들 가운데에는 세포사멸(cell death), 다양한 스트레스 반응성(response to stress/biotic stimulus), 항산화반응(antioxidant activity) 조절자들이 다수 분포하는 것을 확인할 수 있었다.Figure 1a is the result of K-means clustering according to the expression pattern of 3,966 DEGs, and Figure 1b is the result of GO term enrichment analysis for the genes constituting the two clusters classified as above. Cluster 1 shows an increase in expression in radish grown in the open field, especially in individuals showing wind. Among the 2,107 genes constituting Cluster 1, it was confirmed that a large number of regulators of cell death, various responses to stress/biotic stimulus, and antioxidant activity were distributed.
1.2 세포 사멸 관련 유전자들의 발현 양상 분석1.2 Analysis of expression patterns of apoptosis-related genes
상기 1.1의 결과에 근거하여 세포 사멸에 관여하는 유전자들의 발현 변화가 바람들이 정도와 어떠한 상관관계를 갖는지를 측정하였다. 9개의 대표 유전자를 선발하여 바람들이가 관찰된 원교10040호 뿌리 횡절단면의 바깥쪽과 안쪽을 따로 분리하여 총 RNA를 정제하고 quantitative(q) realtime (RT)-polymerase chain reaction (PCR)을 실시하였다. qRT-PCR에 사용된 프라이머의 정보 및 반응 조건은 Hoang 등(Plant J. 2022 Jan;109(1):144-163)에 자세히 기술되어 있다.Based on the results of 1.1 above, it was measured how the expression changes of genes involved in cell death correlate with the degree of wind. After selecting 9 representative genes, the outside and inside of the transverse section of the root of Wongyo No. 10040 where wind was observed were separately separated, total RNA was purified, and quantitative (q) realtime (RT)-polymerase chain reaction (PCR) was performed. . The information and reaction conditions of the primers used for qRT-PCR are described in detail in Hoang et al. (Plant J. 2022 Jan; 109(1):144-163).
도 1c는 RNA를 분리한 바깥쪽과 안쪽 부위를 보여주고 있으며, 도 1d는 바람들이 정도가 약한(index 3) 또는 심한(index 9) 무에서의 9개 유전자 발현 양상을 바깥쪽과 안쪽 무 조직에서 측정한 결과를 보여주고 있다. 도 1d에서 알 수 있듯이 바람들이 정도가 심할수록 세포사멸에 관여하는 유전자의 발현량이 안쪽 부위에서 급격히 증가하는 것을 확인할 수 있었다. 무 안쪽 부위는 물관조직으로 구성되어 있으며, 이는 대부분 유세포(parenchyma cell)로 이루어져 있다. 이상의 결과를 통해 무 바람들이는 물관조직 내의 유세포들이 세포사멸을 겪어 일어난 결과로 결론지을 수 있었다.Figure 1c shows the outer and inner regions from which RNA was isolated, and Figure 1d shows the expression patterns of 9 genes in radishes with weak wind (index 3) or severe wind (index 9) outside and inner radish tissue. The measured results are shown. As can be seen in Figure 1d, it was confirmed that the expression level of genes involved in apoptosis increased rapidly in the inner region as the degree of wind increased. The inner part of the radish is composed of xylem tissue, which is mostly composed of parenchyma cells. Through the above results, it can be concluded that the flow cells in the xylem tissue undergo apoptosis.
실시예 2. 무 바람들이 형질은 세포사멸에 관여하는 NAC 도메인 전사인자인 RsNAC013과 연관되어 있다.Example 2. The radish wind trait is associated with RsNAC013, a NAC domain transcription factor involved in apoptosis.
무 바람들이의 유전적 요인을 탐색하기 위하여 바람들이가 잘 일어나는 원교10040호(WK40)와 바람들이가 잘 일어나지 않는 원교10029호(WK29)를 양친으로 사용하여 F2 분리집단을 제작하였다. F2를 노지에서 키운 후 수확하여 절단면의 바람들이 정도를 도 2(a)의 index에 근거하여 측정하고 바람들이의 분포를 분석하였다. 동일한 분리집단 내 92개 개체에 대하여 게노믹 DNA를 분리하고, 이를 양친 간의 단일염기다형성(single nucleotide polymorphism, SNP)을 이용하여 바람들이 형질과 연관된 유전좌위를 찾기 위한 genotyping by sequencing (GBS) 라이브러리 제작에 사용하였다. GBS 라이브러리를 Illumina 시스템으로 시퀀싱하여 무 유전체 v2.20 (GenBank: GCA_002197605.1)에 대하여 mapping하고, 찾아낸 biparental SNP 가운데 F2에서 1:2:1의 비율로 분리하는 240개의 SNPs를 선발하였다. 240개의 SNPs를 바람들이 형질과 같이 rQTL을 사용하여 분석하여 logarithm of odds (LOD)가 5 이상인 구간을 찾아내었다(도 2b). 구간 내에서 전술한 실시예 1에서 밝힌 세포사멸 관련 DEG을 탐색한 결과, RsNAC013을 발견하였고, RsNAC013이 두 양친 간에 3번 엑손 말단에 다형성을 보여주고 있음을 밝혀내었다(도 2c). RsNAC013의 발현 양상이 바람들이와 연관성을 갖고 있는지를 알아보기 위하여 바람들이 정도가 다른 원교10040호와 바람들이가 없는 원교10029호 무(도 2d)에서의 RsNAC013과 이의 하위 유전자들의 발현을 quantitative RT-PCR로 분석하였다(도 2e). 분석 결과, RsNAC013과 하위 유전자들이 바람들이가 일어나는 원교10040호에서 훨씬 많이 발현되는 것을 확인할 수 있었다. 이는 QTL 분석 결과와 더불어 RsNAC013이 무 바람들이 형질을 유도하는 유전적 요인으로 작용하고 있음을 제시한다.In order to explore the genetic factors of incest, an F 2 segregation group was created using Wongyo 10040 (WK40), which is prone to incest, and Wongyo 10029 (WK29), which is not infrequent, as parents. F 2 was harvested after growing in the open field, and the degree of wind blowing on the cut surface was measured based on the index of FIG. 2 (a), and the distribution of wind blowing was analyzed. Isolate genomic DNA from 92 individuals in the same segregation group, and use single nucleotide polymorphism (SNP) between parents to create a genotyping by sequencing (GBS) library to find genetic loci associated with traits used in The GBS library was sequenced with the Illumina system and mapped against genome-free v2.20 (GenBank: GCA_002197605.1), and among the found biparental SNPs, 240 SNPs separated at a ratio of 1:2:1 in F 2 were selected. 240 SNPs were analyzed using rQTL as in the wind trait, and a logarithm of odds (LOD) of 5 or more was found (Fig. 2b). As a result of searching for apoptosis-related DEGs identified in Example 1 within the section, RsNAC013 was found, and it was found that RsNAC013 showed a polymorphism at the end of exon 3 between the two parents (FIG. 2c). In order to examine whether the expression pattern of RsNAC013 has a correlation with wind blowing, quantitative RT-quantitative RT- It was analyzed by PCR (Fig. 2e). As a result of the analysis, it was confirmed that RsNAC013 and its subgenes were much more expressed in Wongyo 10040, where wind blowing occurred. This, along with the QTL analysis results, suggests that RsNAC013 acts as a genetic factor inducing windless traits.
실시예 3. Example 3. RsNAC013RsNAC013 유전형의 차이를 구별하는 분자 마커는 바람들이 발생 가능성을 예측한다. Molecular markers that distinguish genotype differences predict the likelihood of winds.
도 3a는 원교10040호와 원교10029호의 RsNAC013의 염기서열을 시퀀싱하여 정렬한 결과이다. 여러 SNPs와 더불어 원교10040호에서 총 46개의 염기서열이 3' untranslated region (3' UTR)에서 소실된 것을 확인할 수 있었다. 이러한 염기서열 소실 구간을 포함한 PCR 프라이머 세트[Forward: 5'-TTCAGGAAGGTCTTTGCTGTG-3' (서열번호 3), Reverse: 5'-ATGTACAACTTGAAGAGTTGAACTTATTGA-3' (서열번호 4)]를 제작, 원교10029호와 10040호의 게노믹 DNA를 증폭하여 이를 전기영동으로 분리하였을 때, 도 3b에서 제시하듯이 RsNAC013의 유전형을 쉽게 구별할 수 있었다. 더불어 단백질 코딩 구간 내의 2개의 SNP는 아미노산 서열을 변화시킴을 알 수 있었다(도 3c). 따라서, 두 원교 간의 바람들이 발생의 차이가 아미노산 치환에 의한 기능의 변화에 기인할 가능성을 배제할 수 없었다. 원교10040호와 10029호의 F2 개체들의 바람들이와 RsNAC013의 유전형 차이가 상관관계를 갖는지를 분석하고자 바람들이가 분석된 90개의 F2 개체들의 유전형 분석을 PCR 프라이머 세트를 이용하여 실시하였다(도 3d). 그 결과, 원교10040호의 유전형을 지닌 개체의 바람들이 정도가 심해지는 경향성을 확인할 수 있었다. 또한, 국립원예특작과학원이 보유한 다른 원교(inbred line)들의 RsNAC013 유전형과 바람들이 여부를 비교 분석하였을 때에도 원교10040호의 유전형을 지닌 라인들이 바람들이를 보이는 경향성을 발견할 수 있었다(도 3e).Figure 3a shows the result of sequencing and aligning the nucleotide sequences of RsNAC013 of Wonkyo 10040 and Wonkyo 10029. In addition to several SNPs, it was confirmed that a total of 46 base sequences in Wonkyo 10040 were deleted from the 3' untranslated region (3' UTR). A PCR primer set [Forward: 5'-TTCAGGAAGGTCTTTGCTGTG-3' (SEQ ID NO: 3), Reverse: 5'-ATGTACAACTTGAAGAGTTGAACTTATTGA-3' (SEQ ID NO: 4)] including the missing nucleotide sequence was prepared, and Wonkyo No. 10029 and No. 10040 When genomic DNA was amplified and separated by electrophoresis, the genotype of RsNAC013 could be easily distinguished as shown in FIG. 3B. In addition, it was found that two SNPs in the protein coding region change the amino acid sequence (FIG. 3c). Therefore, it could not be ruled out that the difference in the generation of winds between the two bridges was due to changes in function due to amino acid substitution. In order to analyze whether there is a correlation between the windage of F2 individuals of Wongyo 10040 and 10029 and the genotype difference of RsNAC013 , genotyping of 90 F2 individuals whose windage was analyzed was performed using a PCR primer set (FIG. 3d ). As a result, it was confirmed that the degree of cheating of individuals with the genotype of Wongyo 10040 increased. In addition, when the RsNAC013 genotype and inbred of other inbred lines owned by the National Institute of Horticultural and Herbal Science were compared and analyzed, the lines with the genotype of inbred No. 10040 tended to show inbred (Fig. 3e).
실시예 4. Example 4. RsNAC013RsNAC013 의 다형성은 세포 사멸 관련 하위 유전자의 발현에 영향을 미친다.Polymorphisms in affect the expression of apoptosis-related subgenes.
상기 실시예 3의 결과에서 제시하듯이 RsNAC013은 원교10040호과 원교10029호의 유전형 사이에 3' 뿐만 아니라, 아미노산 서열의 차이를 보여주고 있다(도 3a-c). RsNAC013 단백질은 카르복실기 말단 쪽에 endoplasmic reticulum (ER) 멤브레인에 삽입될 것으로 예측되는 소수성 아미노산 서열을 지니고 있다. 애기장대에서 NAC013은 membrane anchored region이 외부 자극시 절단되어야 핵으로 이동하여 하위유전자의 전사를 조절하는 것으로 알려져 있다.As shown in the results of Example 3, RsNAC013 shows differences in amino acid sequence as well as 3' between the genotypes of Wonkyo 10040 and Wonkyo 10029 (Fig. 3a-c). The RsNAC013 protein has a hydrophobic amino acid sequence at its carboxyl terminus that is predicted to be inserted into the endoplasmic reticulum (ER) membrane. In Arabidopsis, NAC013 is known to regulate subgene transcription by moving to the nucleus only when the membrane anchored region is cleaved upon external stimulation.
본 실시예에서는 RsNAC013의 유전형 차이가 바람들이와 관련된 세포사멸 하위 유전자의 조절을 어떻게 다르게 유도하는지를 분석하고자 하였다. 첫째, 3'의 길이 차이가 전사 후 조절(posttranscriptional regulation)을 다르게 유도하여 RsNAC013 발현량을 다르게 하는지를 살펴보기 위해, 두 원교의 RsNAC013의 3'을 따로 분리하여 nlsGFP 하단에 부착시킨 후 이를 애기장대 뿌리의 비뿌리털세포(atrichoblast)에서 발현하는 유전자인 GLABRA2 (GL2)의 프로모터 조절을 받도록 발현시켰다(도 4a 및 4b). 그 결과, nlsGFP의 발현정도에 있어서 유의미한 차이를 발견할 수 없었다. 둘째, RsNAC013의 아미노산 서열의 차이가 단백질의 세포 내 위치 이동이나 전사인자 활성도에 영향을 주는 지를 살펴보았다. 먼저, 세포 내 위치 이동의 차이 여부를 35S 프로모터 하에 두 유전형의 단백질 코딩 부위를 GFP와 부착시켜 분석하였다(도 4c-f). RsNAC013의 핵으로의 이동은 활성산소 자극에 의해 유도됨에 근거하여, 본 발명에서는 과산화수소를 처리하여 자극시켜 보았다. 그 결과, 자극이 없는 상태(Mock)에서는 GFP-RsNAC013이 ER에 주로 자리하는 것을 보여준 반면, 20mM의 과산화수소를 뿌려 한 시간 처리한 개체의 뿌리에서는 핵에 위치하는 것을 확인할 수 있었다. 서로 다른 유전형의 RsNAC013 행동이 차이를 보이지 않는 것으로 보아, 활성 산소에 의한 핵으로의 이동성에는 차이가 없는 것으로 보였다.In this example, we tried to analyze how the difference in genotype of RsNAC013 induces the regulation of apoptosis-related subgenes differently. First, in order to examine whether the 3' length difference induces posttranscriptional regulation differently and causes the RsNAC013 expression level to differ, the 3' of RsNAC013 of the two bridges was separated and attached to the bottom of nlsGFP, and then Arabidopsis thaliana roots It was expressed under the promoter control of GLABRA2 ( GL2 ), a gene expressed in atrichoblast of ( FIGS. 4a and 4b ). As a result, no significant difference was found in the expression level of nlsGFP. Second, we examined whether differences in the amino acid sequence of RsNAC013 affect the movement of the protein in cells or the activity of transcription factors. First, the difference in intracellular positional movement was analyzed by attaching the protein coding regions of the two genotypes to GFP under the 35S promoter (FIG. 4c-f). Based on the fact that the movement of RsNAC013 to the nucleus is induced by active oxygen stimulation, in the present invention, it was stimulated by treatment with hydrogen peroxide. As a result, it was shown that GFP-RsNAC013 was mainly located in the ER in the absence of stimulation (Mock), whereas it was confirmed that GFP-RsNAC013 was located in the nucleus in the roots of individuals treated with 20 mM hydrogen peroxide for 1 hour. As there was no difference in RsNAC013 behavior of different genotypes, there seemed to be no difference in the mobility to the nucleus by reactive oxygen species.
마지막으로 SNP에 의한 아미노산 서열의 차이가 전사인자 활성도의 차이를 초래하는지를 확인하였다(도 4g-i). 이를 위해, NAC013의 직접적인 표적인 AOX1a (ALTERNATIVE OXIDASE1a)의 NAC013에 대한 상대적 발현량(AOX1a 발현량/NAC013 발현량)을 전사활성도를 측정하는 기준으로 삼았다. 세 가지 다른 접근법으로 분석을 진행하였다. 도 4g는 앞서 도 2d에서 분리한 RNA로부터 측정한 RsAOX1aRsNAC013의 비율을 보여주고 있다. 원교10040호의 RsNAC013의 활성이 훨씬 높은 것을 확인할 수 있다. 도 4h는 온실에서 원교10040호와 원교10029호를 키우면서 과산화수소를 처리하여 활성산소 자극을 주었을 경우와 주지 않았을 경우의 비율을 측정한 것이다. 활성산소 스트레스 자극 시 두 원교 모두에서 RsNAC013의 활성이 증가하였으나, 이 경우에도 원교10040호의 RsNAC013 활성이 높았다. 도 4i에서는 두 RsNAC013 유전형을 각각 애기장대에 형질전환하여 발현시켰을 때 AOX1a의 발현에 미치는 영향을 측정한 것이다. 이 경우에도 역시 원교10040호의 RsNAC013 활성이 더 높은 것을 확인할 수 있었다. 이상의 결과들을 종합해 보면, RsNAC013 가운데 원교10040호 유전형은 원교10029호 유전형에 비하여 전사인자 활성도가 높고, 전사활성도가 높은 RsNAC013 원교10040호 유전형은 스트레스 환경에 반응한 세포사멸을 더 잘 유도함으로써 바람들이가 일어나는 유전적 환경을 제공한다고 결론지을 수 있었다.Finally, it was confirmed whether differences in amino acid sequences by SNPs lead to differences in transcription factor activity (FIG. 4g-i). To this end, the relative expression level ( AOX1a expression level/ NAC013 expression level) of AOX1a (ALTERNATIVE OXIDASE1a), a direct target of NAC013 , to NAC013 was used as a criterion for measuring transcriptional activity. The analysis proceeded with three different approaches. Figure 4g shows the ratio of RsAOX1a and RsNAC013 measured from the RNA isolated in Figure 2d above. It can be confirmed that the activity of RsNAC013 of Wonkyo 10040 is much higher. Figure 4h is a measurement of the ratio of the case where active oxygen stimulation was given and the case where it was not given by treating hydrogen peroxide while growing Wongyo 10040 and Wongyo 10029 in a greenhouse. The activity of RsNAC013 increased in both Wonkyo when stimulated by reactive oxygen species stress, but even in this case, the RsNAC013 activity of Wonkyo 10040 was high. In Figure 4i, the effect on the expression of AOX1a was measured when the two RsNAC013 genotypes were respectively transformed and expressed in Arabidopsis thaliana. In this case, it was also confirmed that the RsNAC013 activity of Wongyo 10040 was higher. Summarizing the above results, among RsNAC013 , the Wongyo 10040 genotype has higher transcription factor activity than the Wongyo 10029 genotype, and the high transcriptional activity of the RsNAC013 Wongyo 10040 genotype induces apoptosis in response to the stress environment better, thereby reducing the wind. It can be concluded that it provides the genetic environment in which
