Stem rot disease was found in garlic (Allium sativum L.) cultivated from 2008 to 2010 in the vegetable gardens of some farmers in Geumsan-myon, Jinju City, Gyeongnam province in Korea. The initial symptoms of the disease were typical water-soaked spots, which progressed to rotting, wilting, blighting, and eventually death. White mycelial mats had spread over the lesions near the soil line, and ...

Sclerotium rolfsii merupakan salah satu patogen penting pada kacang tanah yang dapat menyebabkan penyakit busuk pangkal batang. S. bertahan hidup di dalam dan membentuk struktur dorman. Penelitian ini bertujuan mengevaluasi bakteri endofit dari tanaman brotowali berpotensi sebagai agens hayati efektif untuk mengendalikan mengetahui pengaruhnya pertumbuhan tanah. Bakteri diisolasi akar batang de...

Mycoviruses associated with hypovirulence are potential biological control agents and could be useful to study the pathogenesis of fungal host pathogens. Sclerotium rolfsii, a pathogenic fungus, causes southern blight in a wide variety of crops. In this study, we isolated a series of dsRNAs from a debilitated S. rolfsii strain, BLH-1, which had pronounced phenotypic aberrations including reduce...

AIMS Different cultural conditions for forming and reverting protoplasts were systematically studied to establish a rapid and efficient protocol for Sclerotium rolfsii ATCC 201126. METHODS AND RESULTS Osmotic stabilizer, lytic enzymes and mycelial age were the main factors influencing protoplast yields. An optimized protocol involving 1-h hydrolysis of 45-h-old mycelium with Trichoderma harzi...

Sclerotium-forming filamentous fungi are of great agricultural and biological interest because they can be viewed as models of simple metamorphosis. They differentiate by asexually producing sclerotia but the processes involved in sclerotial metamorphosis were poorly understood. In 1997, it was shown for the first time that the sclerotial differentiation state in Sclerotium rolfsii concurred wi...

BACKGROUND The enzyme cellobiose dehydrogenase (CDH) can be used to oxidize lactose to lactobionic acid. As Sclerotium rolfsii is known to be a good producer of CDH, the aim of this paper was to simplify its production and secondly to systematically study its purification aiming for a high yield. Two preservation methods (freezing and freeze-drying) and the influence of several protectants were...

Pachyrhizus seeds-induced toxicity is very well-known to have developed in humans, fishes, insects, and some micro-organisms. Yet, there a paucity of studies addressing it their germplasm, as well its effects on phytopathogens. This work aimed assess the genetic variability determine extract Sclerotium rolfsii Ralstonia solanacearum vitro. In findings, was shown only diversity immature seeds. I...
