Definitions
- the present invention relates to a transgenic plant in which the content of trace elements is increased by the activation of OsNAS2 gene or OsNAS2 gene of a plant, and a functional food containing a product produced from the transgenic plant.
- Iron is the fourth most abundant element on Earth, but it is not readily accessible by plants. This is because most of the iron in the soil exists in the form of oxyhydrate and has a very low solubility. In addition, about 30% of the world's soil is basic. In soils with these properties, iron is present in the form of Fe 2 O 3 with very low solubility, making plant growth difficult (Mori, Curr Opin Plant Biol 2: 250-253, 1999). This lack of iron has a devastating effect on plants. In particular, iron deficiency affects the synthesis of chlorophyll and the development of chloroplasts, thus reducing the production of plants.
- Iron is also important for human health. Iron is one of the indispensable trace metal elements required for various functions in cells. According to the World Health Organization (WHO), about 30% of the world's population is anemic due to iron deficiency and most of them are concentrated in underdeveloped countries. Zinc deficiency inhibits plant growth, stress tolerance and chlorophyll production. It is also known that zinc plays an important role in the immune response of humans, increasing resistance to infection, and regulating cell growth and wound healing.
- WHO World Health Organization
- Plants are known to overcome iron deficiency in two ways (Marschner et al., J. Plant Nutr 9: 3-7, 1986). Most plants absorb Fe 3+ after they are reduced to Fe 2+ , while rice plants such as rice and barley produce iron-binding substances called phytosiderophore (Fe 3+ ) Thereby increasing the solubility and absorbing the complex of iron and phytocydelopore.
- Rice is an important stock for civilization, and the development of rice varieties containing a large amount of iron is important for promoting human health. Therefore, the cultivation of rice varieties with high iron content by genetic engineering has been proposed as an alternative to overcome the limitations of traditional breeding methods and to solve human health problems caused by iron deficiency (Qu et al., Planta 222: 225- 233, 2005).
- a gene expressing ferritin is isolated from soybean and rice, and then it is combined with an endosperm-specific promoter isolated from globulin, glutelin and jane which are seed storage proteins of rice and corn, Specific expression vectors are prepared and transformed with these expression vectors to describe rice having high iron production capacity.
- this method uses genes derived from soybean, corn and the like other than rice.
- NAAT nicotianamine aminotransferase
- a gene coding for a reducing enzyme that reduces keto to 2'-deoxy myosinic acid of nicotianamine is introduced to produce a plant having enhanced iron deficiency resistance .
- this method uses a gene encoding a reductase that reduces the keto to nicotianamine into 2'-deoxy myosinic acid.
- NA nicotianamine
- NAS Nicotianamine synthase
- Angiotensin converting enzyme an important enzyme in the renin-angiotensin system (RAS), an important mechanism of hypertension, is the most frequently occurring chronic systemic disease. I (angiotensin I: Ang I) to angiotensin II (angiotension II: Ang II). It is known that the converted Ang II contracts blood vessels and increases blood pressure. Thus, for the purpose of improving hypertension, ACE inhibitors have been developed and are commercially available, and there have been several reports showing that nicotianamine acts as an ACE inhibitor (Usuda et al., Plant Biotech J 7: 87-95, 2009).

- the seeds were finely ground using Muilti-Beads Shocker (Yasui kikai, Osaka Japan), and then 20 mg of the powder was extracted with 400 ⁇ l of 80% ethanol for 15 minutes three times to extract nicotianamine.
- the extracted nicotianamine was quantitatively analyzed using LC-ESI-TOF-MS. The results are shown in Table 1 below.
- the amount of nicotianamine in the OsNAS2-D1 seeds was about 19.8-fold higher than that in the wild type.
- OsNAS2-D1 increased 3.0 times iron, 2.7 times zinc, and 1.2 times copper, compared to the wild type. In comparison with wild tongue, OsNAS2-D1 increased 1.4 times in iron and zinc and 1.5 times in copper.
- Example 5 Analysis of seedling phenotype of transgenic plants in the absence of iron and zinc
- Wild type (WT) and OsNAS2- D1 were germinated in MS solid medium containing iron and zinc, MS solid medium (Fe-) without iron, MS solid medium (Zn-) without zinc, And the seedling phenotype was observed. The results are shown in Table 3. In addition, the elongation and chlorophyll contents of the phenotype were measured and shown in Table 3. Chlorophyll was collected from leaves, weighed, and extracted with 80% acetone.
- OsNAS2 - D1 was 1.7 times higher than that of wild type (WT) in stem and root, and the concentration of iron increased 1.5 and 1.7 times in stem and root, respectively .
- WT wild type
- the pH of the soil has a great effect on the solubility of the elements required for the plant. For example, when the pH is 8.0 or more, iron is converted into a Fe 2 O 3 form having a low solubility, so that the plant can not be used and absorbed properly. As a result, iron shortage occurs.
- Wild type (WT) and OsNAS2 - D1 were germinated on MS medium (MS / pH 8.5) adjusted to 8.5 and grown for 10 days and phenotype was observed. The phenotype was also observed by the same method in an iron-free MS medium (Fe- / pH 8.5). The phenotype and the elongation of the plant are shown in Fig. As shown in FIG. 5, it can be seen that OsNAS2 - D1 is more elongated and more resistant to wild type (WT) in MS medium (MS / pH 8.5) adjusted to pH 8.5. These results were more evident in the iron-free MS medium (Fe- / pH 8.5).
- Wild type (WT) and OsNAS2- D1 were germinated in solid MS medium supplemented with excess amount of zinc (5 mM), copper (0.3 mM) or nickel (0.5 mM) and grown for 10 days to observe the seedling phenotype.
- the phenotype, the elongation of the plant and the concentrations of heavy metals are shown in FIG. 6 and Table 5.
- OsNAS2- D1 was taller than the wild type, and the whitening phenomenon progressed less. These results indicate that OsNAS2- D1 is more resistant to toxicity by heavy metals than wild type (WT).
- the concentration of zinc, copper and nickel in the stem and roots was measured by the same method as in Example 4 when grown in solid MS medium containing excessive amounts of zinc, copper and nickel, and the results are shown in Table 6 .
- OsNAS2 - D1 increased 1.4 times, 1.5 times, 1.4 times, 1.4 times, 1.4 times and 1.2 times, respectively, in the roots and roots of wild type (WT).
- a mouse feeding assay was performed to determine whether the increase in iron content of the seeds of OsNAS2-D1 was absorbed by seed intake and the bioavailability of iron used was increased.
- Groups of rats fed the normal diet from the beginning were measured in the control group (control group, CD).
- Hb and Hct were measured by taking blood at 1 week, 2 weeks, and 4 weeks after rice. The results are shown in Table 8. As shown in Table 8, there was no significant difference between the Hb and Hct of the mice until they fed the rice from wild type (WT) or OsNAS2-D1 seeds.
- the Hb and Hct of the two groups were measured, and the second group showed a slight increase in Hb and Hct compared to the first group. After one week, Hb and Hct were measured. In this case, the second group showed a significant increase in Hb and Hct compared to the first group.
- the results were similar to those of the normal feed group, The Hb and Hct of the second group were significantly higher than those of the first group and were similar to the group fed with sufficient iron.

- a mouse feeding assay was performed to determine whether the increase in zinc content of the seeds of OsNAS2-D1 was increased by bioavailability of zinc which was absorbed upon seed ingestion.
- mice weighing approximately 13 g were fed with sufficient feed (30 mg Zn / kg diet, Control Diet (CD)) and zinc-deficient diet (modified AIN-93G diet containing iron 3 mg / kg diet, Iron-depleted Diet (ZD)). Two weeks later, blood was drawn from both groups of rats. The zinc content was measured. As a result, zinc in the blood of rats fed zinc-deficient feeds was reduced to 66% compared to rats fed enough feed of zinc (Table 9).
- Table 9 A group of rats fed zinc with sufficient feed Group of rats fed with zinc-deficient feed Zn ( ⁇ ⁇ / ml) 2.017 + 0.260 1.341 + 0.187
- Zinc levels were measured in rats fed a normal diet as controls. Blood samples were taken at 2, 6, 10, 15, 20 and 30 days after feeding with normal diet and rice. The results are shown in Table 10. As shown in Table 10, it was found that the zinc level increased from two days after feeding the normal diet or rice.
- the group fed the OsNAS2-D1 seed showed similar zinc levels to the group fed the normal diet in 10 days, while the group fed the wild-type seeds still showed a low level after 30 days.
- the zinc-deficient diet and the group that changed to normal diet also had zinc levels that were similar to those of the group that had been fed from the beginning to about 20 days.
- the present inventors have also found that the rice varieties OsNAS2-D1 having an increased amount of trace metals obtained in the above-mentioned Examples were used as a result of a study by the International Depositary Authority (Korea Research Institute of Bioscience and Biotechnology) Research Institute of Bioscience and Biotechnology: KRIBB), and received seed accession number KCTC 11597BP.
- Nicotianaamine synthase (OsNAS1, OsNAS2 , OsNAS3 ) is present in rice and has activity as an enzyme (Inoue et al., Plant J 36: 366-381, 2003). The expression level of the above 3 genes according to presence or absence of trace elements was examined. Rice seeds were germinated in MS (Murashige and Skoog) medium (containing 0.1 ⁇ M CuSO 4 , 100 ⁇ M Fe (III) -EDTA, 30 ⁇ M ZnSO 4 , 10 ⁇ M MnSO 4 ) and grown for 7 days.

- Wild type (WT) and OsNAS3- D1 were germinated in the solid MS medium supplemented with excess zinc (5 mM), copper (0.3 mM) or nickel (0.5 mM) and grown for 10 days to observe the seedling phenotype.
- the phenotype and the elongation of the plant are shown in Fig.
- OsNAS3- D1 was taller than the wild-type and less bleached . These results indicate that OsNAS3- D1 is more resistant to toxicity by heavy metals than wild type (WT). Particularly, when grown in solid MS medium containing excessive zinc, the zinc concentration in the stem and root was measured in the same manner as in Example 11, and the results are shown in Table 14. [
- OsNAS3- D1 showed a 2.3-fold higher zinc concentration in the stem than the wild type (WT).
- Example 14 Phenotypic observation of transgenic plants under high pH conditions

For example, if the pH is greater than 8, the iron is converted to Fe 2 O 3, which has a low solubility, and the plant is in a state where it can not be used or absorbed properly. As a result, iron shortage occurs.
- Wild type (WT) and OsNAS3- D1 were germinated on MS medium (MS) adjusted to pH 8.5 and grown for 10 days.
- the phenotype was also observed in the MS medium (Fe -) (pH 8.5) containing no iron by the same method.
