초록

고구마는 척박한 환경에서도 생육이 가능한 세계 7대 농작물로 식량뿐만 아니라 사료용, 전분 등의 산업용으로도 중요하다. 최근 고구마는 항산화물질, 식이섬유질 등을 고함유하는 건강식품으로 각광을 받고 있다. 그러나 고구마 유전체 해독에 관한 연구는 고구마의 중요도에 비해 많이 이루어지지 않고 있다. 본 총설의 목적은 고구마 유전체 연구 동향분석을 통하여 유전체 해독 연구의 효율성 증대 및 유용형질 유전자의 실용화 연구를 위한 기반구축을 모색하는데 있다. 최근 NGS 분석을 통한 동식물 유전체해독이 급진적으로 많이 이루어지고 있다. 고구마 유전체 해독의 경우는 다배수성 문제와 이질유전체 문제로 유전체 완전해독 연구가 이루어지지 않고 있으며 반면 전사체 분석 연구는 활발히 이루어지고 있는 실정이다. 최근 2015년 일본 연구자들에 의해 2배체 고구마의 유전체 해독 초안이 보고되었다. 한중일 고구마 연구협의회(Trilateral Research Association of Sweetpotato, TRAS)에 의해 6배체 고구마 Xushu 18의 유전자지도 작성 및 유전체 해독 연구가 2014년부터 이루어지고 있다. 빌게이츠재단(Bill & Melinda Gates Foundation)은 사하라사막 남쪽 아프리카지역의 기근과 영양문제를 해결하기 위해 고구마 유전체 기반 분자육종을 위한 분자도구 개발에 관한 프로젝트를 미국을 중심으로 한 컨소시엄을 구성하여 출범하였다. 고구마 유전체 해독과정 중에 분석된 고구마 엽록체 유전체 분석을 통하여 진화학적 해석연구가 이루어지고 있다. 본 총설을 통하여 고구마 유전체 해독 연구동향을 살펴보았다. 이러한 연구 동향 분석은 고구마의 생산성 및 기능성 향상 등의 실용화 연구를 수행하는 연구자들에게 최근의 연구현황을 제공할 수 있을 것이며 세계적인 식량, 에너지, 환경문제의 해결에 크게 기여 할 것으로 생각된다.

Sweetpotato [Ipomoea batatas (L.) Lam] grows well in harsh environmental conditions, and is cultivated as one of the top seven food crops in the world. Recently, sweetpotato is drawing interest from people as a healthy food because it is high in dietary fiber, vitamins, carotenoids and overall nutrition value. However, few studies have been conducted on sweetpotato genome sequencing in spite of its importance. This review is aimed at increasing the efficiency of sweetpotato genome sequencing research as well as establishing a base for gene utilization in order to control useful traits. Recently, animal and plant genome sequencing projects increased significantly. However, sweetpotato genome sequencing has not been performed due to polyploidy and heterogeneity problems in its genome. Meanwhile research on its transcriptome has been conducted actively. Recently, a draft of the diploid sweetpotato genome was reported in 2015 by Japanese researchers. In addition, the Korea-China-Japan Trilateral Research Association of Sweetpotato (TRAS) has conducted research on gene map construction and genome sequencing of the hexaploid sweetpotato Xushu 18 since 2014. The Bill & Melinda Gates Foundation launched the 'sweetpotato genomic sequencing to develop genomic tools for Sub-Sahara Africa breeding program'. The chloroplast genome sequence acquired during sweetpotato genome sequencing is used in evolutionary analyses. In this review, the trend of research in the sweetpotato genome sequencing was analyzed. Research trend analysis like this will provide researchers working toward sweetpotato productivity and nutrient improvement with information on the status of sweetpotato genome research. This will contribute to solving world food, energy and environmental problems.
