A chitinolytic bacterial strain having strong antifungal activity was isolated and identified as Burkholderia cepacia MPC-7 based on 16S rRNA gene analysis. MPC- 7 solubilized insoluble phosphorous in hydroxyapatite agar media. It produced gluconic acid and 2-ketogluconic acid related to the decrease in pH of broth culture. The antagonist produced benzoic acid (BA) and phenylacetic acid (PA). The authentic compounds, BA and PA, showed a broad spectrum of antimicrobial activity against yeast,...

We identified two novel expansin (EXP) genes in the expressed sequence tag database of Bursaphelenchus xylophilus, designated as Bx-EXPB2 and -EXPB3. Novel Bx-EXPBs encoded 150 amino acids and their similarities in coding sequence were 70.7?84.0% to the previously reported EXPB1 of B. xylophilus. Bx-EXPB2 and Bx-EXPB3 were clustered with Bx-EXPB1 and Bm- EXPB1, respectively, forming the independent phylogeny with other nematode EXPs. All identified Bx-EXPBs contained the signal peptide and were...

During investigating of shiitake mushroom competitors, 289 isolates of Trichoderma spp. were collected from shiitake mushroom farms in different districts and the Forest Mushroom Research Center of Korea, among which 29 representative strains were selected. Based on the DNA sequences of the rpb2 and tef1 genes and the ITS rDNA, and their morphological characteristics, they were identified as T. atroviride, T. citrinoviride, T. harzianum, T. longibrachiatum, and two undescribed species,...

Soybean plants infected with Bean pod mottle virus (BPMV) develop acute symptoms that usually decrease in severity over time. In other plant-virus interactions, this type of symptom recovery has been associated with degradation of viral RNAs by RNA silencing, which is accompanied by the accumulation of virus-derived small interfering RNAs (siRNAs). In this study, changes in the accumulation of BPMV siRNAs were investigated in soybean plants infected with BPMV alone, or infected with both BPMV...

Root colonization of Arabidopsis thaliana with Pseudomonas chlororaphis O6 induces systemic tolerance against diverse pathogens, as well as drought and salt stresses. In this study, we demonstrated that 11 genes in the leaves were up-regulated, and 5 genes were down-regulated as the result of three- to five-days root colonization by P. chlororaphis O6. The identified priming genes were involved in cell signaling, transcription, protein synthesis, and degradation. In addition, expression of...

In order to control postharvest spoilage of satsuma mandarin fruits, rhizobacteria were isolated from soil samples. The Pantoea agglomerans strain 59-4 (Pa 59-4) which suppresses the decay of mandarin fruit by green and blue mold, was tested for the control efficacy and its mode of action was investigated. Pa 59-4 inhibited infection by green and blue mold on wounded mandarins, which were artificially inoculated with a spore suspension of Penicillium digitatum and P. italicum with control...

A logistic model for describing combined effects of both temperature and wetness period on appressorium formation was developed using laboratory data on percent appressorium formation of Colletotrichum acutatum. In addition, the possible use of the logistic model for forecasting infection risks was also evaluated as compared with a first-order linear model. A simplified equilibrium model for enzymatic reactions was applied to obtain a temperature function for asymptote parameter (A) of logistic...

식물 근권에서 180 균주를 분리하여 뿌리혹 선충(Meloido- gyne incognita)의 알 부화율 억제 효과가 있는 34개 균주를 일 차적으로 선발하였고, 이들 중 알 부화율과 유충 억제에 모두 효과가 있는 세균 JC05와 CT16을 선발하였다. 두 균주는 각각 Bacillus sp. CT16과 Neobacillus sp. JC05로 동정하였으며, 두 균 주의 배양액을 용매로 추출 및 농축한 후 선충의 알 부화율을 평가한 결과, JC05의 n-butanol 추출물은 25 μg/ml이상의 농도 에서 알의 부화를 효과적으로 억제했으며, CT16의 n-hexane과 n-butanol 추출물에서는 각각 25...

고추 역병의 감염위험도 예측모델인 PBcast 포장검증 연구를2012-2013년 동안 수행하였다. 그리고 2014-2017년 동안 우리나라 26개 지점에서 PBcast 모델을 이용하여 발병환경을 평가하였다. PBcast 모델은 기상과 토성자료를 이용하여 Phytophthora capsici의 일일 감염위험도를 추정한다. 시험포장에서 7일 간격으로 살균제를 살포하는 정기방제(RTN7) 처리, 예측된 감염위험도가 200 이상(IR200), 224 이상(IR224)일 때 살포하는 예찰방제 처리, 무방제(CTRL) 처리를 발병주율과 살균제 살포횟수로 비교하였다. 2012년에 감염위험도가...
