  • In 2014, the United Nations Framework Convention on Climate Change (UNFCCC) agreed to submit the Intended Nationality Determined Contributions (INDCs) at the conference of parties held in Lima, Peru. Then, the South Korean government submitted the INDCs including GHGs reduction target and reduction potential on July, 2015. The goal of this study is to predict GHGs emission and to analyze reduction potential in agricultural sector of Korea. Activity data to estimate GHGs emission was forecast by Korea Agricultural Simulation Model (KASMO) of Korea Rural Economic Institute and estimate methodology was taken by the IPCC and guideline for MRV (Measurement, Reporting and Verification) of national greenhouse gases statistics of Korea. The predicted GHGs emission of agricultural sectors from 2021 to 2030 tended to decrease due to decline in crop production and its gap was less after 2025. Increasing livestock numbers such as sheep, horses, swine, and ducks did not show signigicant impact the total GHGs emission. On a analysis of the reduction potential, GHGs emission was expected to reduce $253Gg\;CO_{2-eq}$. by 2030 with increase of mid-season water drainage area up to 95% of total rice cultivation area. The GHGs reduction potential with intermittent drainage technology applied to 10% of the tatal paddy field area, mid-drainage and no organic matter would be $92Gg\;CO_{2-eq}$. by 2030.

  • Phytophthora capsici is the organism that causes Phytophthora blight which infects red pepper plants prolifically, ultimately leading to crop loss. A previous study revealed that Enterobacter asburiae ObRS-5 suppresses Phytophthora blight in both red pepper and Ligularia fischeri plants. In order to determine whether the induced systemic resistance (ISR) was triggered by pre-infection with the ObRS-5 strain, we conducted quantitative PCR using primers for PR1, PR4, and PR10, which correlate with systemic resistance in red-pepper plants. In our results, red pepper plants treated with the ObRS-5 strain demonstrated increased expression of all three systemic resistance genes when compared to controls in the glasshouse seedling assay. In addition, treatment of red peppers with the ObRS-5 strain led to reduced Phytophthora blight symptoms caused by P. capsici, whereas all control seedlings were severely affected. Perhaps most importantly, E. asburiae ObRS-5 was shown to induce the ISR response in red peppers without inhibiting growth. These results support that the defense mechanisms are triggered by ObRS-5 strain prior to infection by P. capsici and ObRS-5 strain-mediated ISR action are linked events for protection to Phytophthora blight.

  • 먹는 것이 아니어서 유전자변형작물(GM작물)로서의 거부감이 덜할 뿐 아니라 고부가 창출가능성이 높아 최근 GM 화훼류 개발에 대한 관심이 높아지고 있다. 이러한 연구 환경에 맞춰 농촌진흥청에서는 형질전환 기술을 이용하여 일반적인 교잡 육종 기술로 개발하기 쉽지 않은 불량 환경인 고염도와 물이 공급되지 않은 조건에서도 견디는 능력이 탁월하게 증진된 장미를 개발했다.

  • 아직까지 국내에서 GM작물이 상업화를 위해 승인된 예는 없지만 생명공학기술의 발전으로 GM작물의 개발은 급속한 증가 추세에 있다. 비의도적인 방출로 인해 미승인 LMO 목화가 전국적으로 재배되어 국립종자원 주관으로 양성 판정된 재배지의 목화를 폐기 처분하였으나(2017), GM작물이 유해하다는 인식과 환경에 방출되어 생태계를 교란시킨다는 인식이 팽배해 있는 현실에서 과학적으로 유전자의 이동성을 검증하는 노력이 중요하다. 자식성 작물의 화분의 이동성 조사를 위해 중앙의 코어 위치에 LM작물을 식재한 후 LM작물 주변에 재배품종을 심어 유전자이동 가능성을 조사하고 재배 환경에 의한 영향을 평가하기 위해 포장 주변 기상상황 데이터-온도, 습도, 풍속, 풍향, 기압, 강수량 등을 분석하고 기상상황이 화분의 전이에 미치는 영향 조사하였다.
