To evaluate effects of ligninolytic enzyme type on the mycelial response and ligninolytic enzyme production during interspecific interactions among wood-rotting fungi, 4 fungal strains, Trichophyton rubrum LKY-7, Trichophyton rubrum LSK-27, Pycnoporus cinnabarinus, and Trichoderma viride, were selected. Regarding ligninolytic enzyme production, LKY-7 secreted laccase and manganese peroxidase (MnP), P. cinnabarinus secreted only laccase, and LSK-27 secreted only MnP in glucosepeptone medium, while T. viride did not produce any ligninolytic enzymes. In the co-culture of LKY-7 with P. cinnabarinus, the formation of aerial mycelium was observed and the enhancement of laccase activity owing to interspecific interaction appeared to be very low. In the co-culture of LKY-7 and P. cinnabarinus with LSK-27, a hypha-free clear zone was observed, which resulted in deadlock, and increased laccase or MnP activity was detected at the interaction zone. The interaction responses of LKY-7, P. cinnabarinus, and LSK-27 with T. viride were characterized by the formation of mycelial barrages along the interface. As mycelial barrages were observed at the T. viride territory and no brownish pigment was observed in the mycelial barrages, it is suggested that laccase and MnP are released as part of an offensive response, not as a defensive response. The co-culture of P. cinnabarinus with T. viride lead to the highest enhancement in laccase activity, yielding more than 14-fold increase in laccase activity with respect to the mono-culture of P. cinnabarinus. MnP activities secreted by LKY-7 or LSK-27 was generally low in interspecific interactions.

본 연구는 전라북도에서 이용되는 민속식물을 파악하 기 위하여 2013년 3월부터 2014년 7월까지 수행하였다. 11개 시∙군지역의 주민 59명을 대상으로 수집한 885 건의 설문조사를 분석한 결과, 민속식물은 총 66과 137 속 140종 2아종 12변종으로 총 154분류군이 확인되었 다. 지역별로는 완주시가 135분류군으로 가장 많았고, 고 창군이 128분류군, 무주군 104분류군, 진안군 103분류군, 부안군 87분류군, 정읍시 69분류군 등의 순으로 높게 나 타났다. 용도별 이용은 식용 112종류, 약용 62종류, 관상 4종류, 염료 3종류, 유지 3종류, 향료 1종류, 수액 1종류, 향신료 1종류, 기타 9종류로 식용과 약용의 이용 빈도가 높았으며, 이용부위로는 잎, 열매, 줄기, 뿌리, 전체 순으 로 나타났다. 표준식물명과 각 시∙군별 지방명의 일치 에서는 무주 (59.4%), 완주 (51.8%), 부안 (51.0%), 고창 (50.4%), 순창(46.3%) 등의 순으로 높게 나타났다. 전반 적으로 민속식물의 이용정보는 대부분 구전으로 습득하 였다.
