Abstract

A. bisporus is the fifth most cultivated mushroom in Korea, and approximately 10,757 tons were cultivated in 2015. The genetic diversity of collected strains in Korea and commercial cultivars was analyzed using inter-simple sequence repeat (ISSR) markers. ISSR markers known to be comparable among A. bisporus spp. were selected from various markers. Totally, 16 markers, namely the ISSR markers 807, 808, 810, 811, 834, 835, 836, 841, 842, P3, P8, P17, P22, P30, P38, and P39, were evaluated to discriminate between ASI 1110, 1114, 1115, 1238, 1246, 1365, 1366, and 1369 for selecting suitable markers in 16 markers. The ISSR markers P31, P38 and P39 exhibited various fingerprints that could help classify the strains in species. Using the three markers, genetic relationships among 39 strains, including commercial cultivars, such as SaeA and SaeYeon, were analyzed using the UPGMA method. The results of the analysis of the genetic relationships between commercial cultivars and collected strains in Korea confirmed that the commercial cultivars were different from the collected strains in Korea. These results suggested that the ISSR markers P31, P38, and P30 could be used for selecting the commercial cultivars of A. bisporus.

양송이(Agaricus bisporus)는 국내에서 2015년 약 10,757톤이 생산되어 5번째로 많이 생산되는 버섯이다. 본 연구에서는 ISSR 마커를 사용하여 국내 수집균주와 상업품종간의 유전적 다양성을 분석하였다. 이를 위해 우선, 다양한 마커 중 양송이 속 내 비교 분석이 가능다고 알려진 ISSR마커를 선발하였다. 분석한 마커는 ISSR 807, 808, 809, 810, 811, 834, 835, 836, 841, 842, P3, P8, P17, P22, P30, P38 and P39 총 16종이였고 이들 중 육종에서 모본선발을 위한 효율적인 마커를 선발하기 위하여 양송이 수집균주 ASI 1110, 1114, 1115, 1238, 1246, 1365, 1366, 1369 등 8종을 선발하여 수행하였다. 그 결과 ISSR P31, P38, P39 마커에서 종내 구분이 가능한 다양한 밴드가 나타났다. 이를 바탕으로 선발된 3종의 마커를 이용하여 국내 수집균주와 새아, 새연 등의 상업품종이 포함된 39균주를 UPGMA 프로그램을 통하여 유연관계를 분석하였다. 국내 수집균주와 상업품종간의 계통도를 분석한 결과, 국내 수집균주와 상업품종들이 다른 그룹을 형성하는 것을 확인하였다. 이 결과를 근거로 ISSR P31, P38, P39가 상업품종을 구분할 수 있는 마커로 활용될 것이라 기대된다.
