Pectobacterium carotovorum subsp. carotovorum (Pcc) is a gram-negative, broad host range bacterial pathogen which causes soft rot disease in potatoes as well as other vegetables worldwide. While Pectobacterium infection relies on the production of major cell wall degrading enzymes, other virulence factors and the mechanism of genetic adaptation of this pathogen is not yet clear. In the present study, we have performed an in-depth genome-wide characterization of Pcc strain ICMP5702 isolated from... -
Pathogenicity Determinants of Sclerotinia sclerotiorum and Their Association to Its Aggressiveness on Brassica juncea

White rot or stem rot caused by Sclerotinia sclerotiorum is one of the most destructive fungal diseases that have become a serious threat to the successful cultivation of oilseed Brassicas. The study was designed with an aim to investigate the association between the pathogenic aggressiveness and pathogenicity determinants of this pathogen specifically in Brassica for the first time. For this, a total of 58 isolates of S. sclerotiorum from differ- ent geographical regions were collected and... -

그 농도, 시간에 비례하였다. Cellulase (Cx), endo-polygalacturonase(endo-PG), endo-poiymethylgalacturonase (endo-PMG), exo-polygalacturonase (exe-PG)와 exo-polymeth-ylgalacturonase(exo-PMG)의 역가는 접종후 4 일째 최대였으며 endo-PG와 endo-PMG는 1일 및 2일째는 전혀 검출되지 않았으나 exo-PG와 exo-PMG는 검출되었다. 접종후 6 일째에는 모든 펙틴질분해효소는 활성을 완전히 잃었으나 섬유소분해효소는 높은 역가을 유지하였다. Cx, endo-PG, endo-PMG, exo-PG 및 exo-PMG의 최적 pH는 각각 6.0, 5.5, 8.0, 7.0-7.5,... -

높은 $S_2$균주와 병원성이 낮은 $R_2$균주가 endo-polymethylgalacturonase, endo-polygalacturonase, pectin methyl-trans-eliminase, polygalacturonate-trans-eliminase를 생산하였으며 두균주간의 효소활성에 있어서 현저한 차이는 없었다. 사과배지에서는 위의 4개의 효소가 모두 생산되었으나 endo-polymethylgalacturonsae, endo-polygalacturonase의 활성은 병원성이 높은 $S_1$균주가 병원성이 낮은 $R_2$균주보다 6배 이상 높은 활성을 보였으나 pectin methyl-trans-eliminase와 polygalacturonate-trans-eliminase의 활성은...
