한국식물병리학회 The Plant Pathology Journal 2021, 37권 2호 1 87-98 (12 pages)
To establish an infection, fungal pathogens must recog- nize diverse signals from host surfaces. The rice blast fungus, Magnaporthe oryzae, is one of the best models studying host-pathogen interactions. This fungus recog- nizes physical or chemical signals from the host surfac- es and initiates the development of an infection struc- ture called appressorium. Here, we found that protein MoAfo1(appressorium formation, MGG_10422) was involved in sensing signal molecules such as cutin mono- mers and... -

Lesion mimic mutant (LMM) plants display spontaneous necrotic lesions on their leaves without any pathogenic infection. Specific rice LMMs designated as spotted leaf (spl) including spl1, spl3, spl4, spl5 and spl6 are genetically known as lesion resembling disease (lrd) mutant. The inheritance patterns in the F1 and F2 progenies of these mutants are controlled by recessive genetic factors. Lesion development in the rice LMMs were controlled by both development stages and environmental factors.... -

Several species belonging to the Gibberella fujikuroi species (Gf) complex are commonly associated with rice and corn, not only causing serious diseases, but also producing fumonisins, a group of mycotoxins harmful to animals and humans. To characterize the population structure of the putative fumonisin-producing Gf complex in Korea, we obtained 276 candidate isolates from rice and corn harvested in 2009 and 2010 by diagnostic polymerase chain reaction with several specific primer sets.... -

하천생태계는 환경, 생태적 중요한 가치를 지니는 공간이지만 최근 다양한 위협에 처해있다. 다양한 복원이 시도되고 있어 유형에 따른 식생특성 발달 정도를 평가하였다. 제방형태 중 자연형제방이 42∼45 종류, 인공형제방이 23∼38 종류로 확인되어 자연형제방이 인공형제방에 비해 식생의 다양함을 확인하였다. 더불어 자연형 제방에서 인공형 보다 꿀풀과와 사초과가 발달함을 확인하였다. 일년생식물의 출현빈도는 인공형제방 지역이 낮은 빈도임을 확인 하여 하천정비 시 일년생식물이 도입 될 수 있도록 서식공간을 넓게 조성 할...
