Abstract

Pyropia species are red algae with a heteromorphic life cycle consisting of a blade gametophyte and a filamentous sporophyte (conchocelis). Free-living conchocelis grows freely in liquid culture without penetrating calcareous substrates and can be maintained and propagated for long periods under laboratory conditions. This review summarizes the isolation methods, culture conditions, and applications of free-living conchocelis. It is commonly established from carpospores, and its growth and maturation are regulated by temperature, irradiance, photoperiod, and nutrient availability. Free-living conchocelis has been widely used for germplasm preservation, seed production, breeding programs, and environmental stress studies. Recent advances have expanded its applications to molecular research and the development of high-temperature tolerant cultivars. This review provides fundamental information for the effective utilization of free-living conchocelis in Pyropia research and seed production.

김(Pyropia spp.)은 엽상체 배우체와 사상체 포자체가 교대로 출현하는 이형세대교번 생활사를 갖는 홍조류이다. 유리사상체(free-living conchocelis)는 패각과 같은 탄산칼슘 기질에 잠입하지 않고 액체 배지에서 자유롭게 생장하는 사상체로, 장기간 보존과 대량 증식이 가능하다. 본 논문에서는 유리사상체의 확보 방법, 배양 조건 및 활용 분야를 정리하였다. 유리사상체는 주로 과포자로부터 확보되며, 온도, 광량, 광주기 및 영양염 조건에 따라 생장과 성숙이 조절된다. 또한 유전자원 보존, 종자 생산, 육종 및 환경 스트레스 연구에 활용되고 있으며, 최근에는 분자생물학 연구와 고수온 내성 품종 개발에도 이용되고 있다. 본 논문은 김 유리사상체의 효율적인 활용과 종자 산업 발전을 위한 기초자료를 제공하고자 한다.
