Xcv에 감염된 고추는 어떤 특징을 갖는가? | vesicatoria (Xcv)는 식물체의 각 부분에 발병하지만 주로 잎에 황녹색의 점무늬를 나타내며 병반이 점차 확대되면 잎 전체가 황화되어 조기 낙엽을 유발한다. Xcv에 감염된 고추는 HR 반응과 함께 유전자-유전자 간의 상호 작용에 의해 병에 대한 저항성이 조절된다[22]. 병원체에 의해 고추에 유도 된 CaLRR1(Leucine-rich repeat)은 5개의 glycosylation 부위와 5개의 LRR domain을 가지며 효소 억제제, 리보솜 결합 단백질, 호르몬 수용체 등 다수의 활성 단백질의 주요 구조에서 발견된다[23−26]. | |
Protein kinase이란? | Protein kinase는 유전자의 발현, 세포의 성장과 분화 조절에 관여하는 생물학적 시스템의 주요 요소이며[31, 32], 병원균을 인식하여 식물의 방어 반응을 유발하는데 필수적 단백질이다[33, 34]. Protein kinase의 하나인 CaPIK1은 VIGS (virus-induced gene silencing) 방법을 이용하여 CaPIK1 knockdown 된 고추 식물체에서 Xanthomonas campestris pv. | |
CO2가 식물 병원성 미생물에 미치는 직간접적인 영향의 예로 무엇이 있는가? | CO2는 식물에 직접적인 생물학적 영향을 미칠 수 있는 요소이며, 식물 병원성 미생물에도 직접 또는 간접적으로 영향을 미친다[2, 3]. 식물 병원성 세균인 Erwinia carotovora와 Pseudomonas fluorescens는 높은 CO2 농도에서 생장 저해를 받으며, 식물 병원성 곰팡 이인 Phytophthora capsici는 포자 형성에 영향을 받는다는 연구결과가 이미 보고되었다[4, 5]. 1990년대부터 영국, 호주, 미국, 독일 등 많은 나라에서 CO2 농도 증가와 병원성 미생물에 대한 연구를 발표하였으나 대부분 350 ppm에서 700 ppm으로 증가하였을 때의 결과이며, 빠르게 변하는 기후 하에서 병원균과 기주 식물간의 새로운 데이터는 매우 부족한 실정이다[6, 7]. |
