Abstract

Blueberry (Vaccinium spp.) is a bush that grows well at special cultural environments such as acid soil, high organic matter content, and a good drainage and aeration compared to other general crops. Blueberries are well known to contain high amounts of anthocyanins and phenolic compounds, resulting in high antioxidant activity that provides health benefits, and expanding the cultivation areas and consumer's demand in the worldwide. However, the full genome of blueberry has not been announced until now. Furthermore, the genomic analysis and transcriptome approaches are not so popular compare to major crops such as orange, apple, and grape. The aim of the review about blueberry genomic research is to establish the platform for setting blueberry breeding target, increasing proficiency of blueberry research, and making the practical cultivation techniques in Korea. The main topics in the blueberry genomic research including transcriptome, genetic mapping, and various markers are related with cold hardiness, chilling requirement, hot tolerance, anthocyanin content, and flavonoid synthesis pathway on various tissues like flower bud, leaf bud, shoot, root, and berry fruit. The review of the current status of blueberry genomic research will provide basic information to the breeders and researchers and will contribute to development of blueberry industry with sustainable productions and increase of blueberry consumption as new profitable crops in Korea.

블루베리는 유기물 함량이 높고 통기성과 배수성이 양호한 산성토양에서 생육이 우수한 관목식물이다. 블루베리 과실은 안토시아닌 함량이 높고 항산화 활성이 우수한 기능성 과실로서 소비자 수요가 급증하고 있으며 전 세계적으로 재배면적이 급속하게 증가하고 있다. 그러나 아직까지 블루베리 전체 유전체에 대한 해독이 이루어지지 않았으며, 타 작목에 비하여 유전체 연구가 많이 이루어지지 않고 있다. 본 총설의 목적은 블루베리 유전체 연구현황 분석을 통하여 국내 블루베리 유전체 연구에 대한 목표 설정, 효율성 증진, 실용화 방안에 대한 플랫폼을 구축하는데 있다. 지금까지의 블루베리 유전체, 전사체, 마커에 대한 연구는 블루베리의 내한성, 저온요구도, 환경적인 스트레스 요인에 대한 이해 증진과 재배 적응성을 높이기 위한 식물학적 이해와 우량 계통 및 품종 선발에 대한 육종 효율성을 높이기 위한 목표로 연구가 수행되었다. 본 총설에서 살펴본 블루베리 유전체 연구에 대한 현황분석은 국내의 유전체 연구자 및 블루베리 연구자들에게 국내환경에서 보다 재배적응성이 우수하고 지속적이며 고기능성의 과실생산을 위한 품종 육성과 재배기술 연구에 대한 기초자료를 제공할 것이며 국내에서 신소득 과수로서 블루베리가 정착하고 발전하는데 크게 기여할 것으로 생각된다.
