To enhance Bacillus thuringiensis (Bt) efficacy, four Cry toxins were purified from four different Bt strains and assessed in their combined efficacy. The Cry mixtures significantly expanded their target insect spectra. Bacterial culture broth of Xenorhabdus nematophila (Xn) significantly suppressed...

활성화된 독소단백질의 살충기작은 어디서부터 시작되는가? | 활성화된 독소단백질의 살충기작은 중장막의 수용체에 결합으로부터 시작된다. Cry1Ab의 경우 캐드헤린과 같은 높은 결합력(Kd=1 nM)을 갖는 세포막 단백질에 결합된 Cry는 이 단백질 domain I에 위치한 첫 번째 α 구조 부위가 제거되면서 Cry 올리고 형성이 일어나게 된다. | |
곤충의 면역반응의 특징은? | 이들을 방어하기 위해 곤충은 다양한 생리작용을 가지고 있지만, 이 가운데 가장 효율적 방어기작이 면역반응이다(Beckage, 2008). 곤충의 면역반응은 척추동물과는 달리 선천성 반응만 지니고 있다. 이 선천성 면역반응은 세포성 면역반응과 체액성 면역반응으로 구분된다. | |
곤충이 다양한 병원 미생물의 공격에 방어하기 위해 가진 기작 중 가장 효과적인 것은? | 여러 환경에 서식하는 곤충은 다양한 병원 미생물의 공격에 노출된다. 이들을 방어하기 위해 곤충은 다양한 생리작용을 가지고 있지만, 이 가운데 가장 효율적 방어기작이 면역반응이다(Beckage, 2008). 곤충의 면역반응은 척추동물과는 달리 선천성 반응만 지니고 있다. |
