Clubroot symptoms occurred severely on roots of Pak-Choi (Brassica campestris ssp. chinensis) grown in greenhouses in Gwangju city, Gyeonggi province, Korea in September, 2008. The incidence of the disease symptoms reached as high as 90% in three greenhouses investigated. The root galls collected from the greenhouses were sectioned using a scalpel and observed by light microscope. Many resting ...

The object of this research was to find an alternative to fungicide for the prevention of postharvestfruits. Therefore the effect of Zataria multiflora essential oil on the quality of Sultana grapes followingthe harvest was investigated. The essential oil was extracted by hydro-distillation and analyzed using acombination of GC and GC/MS. The results indicated a high percentage of anti-fungal c...

Physico-chemical properties of Aspergillus conidia rely on their outer cell-wall rodlet layer. In A. fumigatus and A. nidulans, the rodlet structure is due to an hydrophobin encoded by homologous rodA genes. To evaluate the role of the rodlet structure on the physico-chemical properties of conidia, we compared hydrophobicity, Lewis acid-base (i.e. electron donor/acceptor) characteristics and el...

After publishing results of a study that revealed diarrheagenic and emetic activity in 4-5-day old mice infected with Kudoa septempunctata (K. septempunctata) spores, the Korea Centers for Disease Control and Prevention reported 11 events of "Kudoa food poisoning" in 2015. The epidemiological design of the previous study was descriptive rather than analytical; therefore, this study aimed to fur...

Ganoderma lucidum (G. lucidum) spores as a valuable Chinese herbal medicine have vast marketable prospect for its bioactivities and medicinal efficacy. This study aims at the development of an effective and simple analytical method to distinguish G. lucidum spores from its fruiting body, which is of essential importance for the quality control and fast discrimination of raw materials of Chinese...

In this study, we investigated the inactivation characteristics of Geobacillus stearothermophilus spores under different plasma exposure conditions using low-pressure microwave plasma in nitrogen, oxygen and an air-simulated (N2 : O2 = 4 : 1) gas mixture. The microwave-excited surfacewave plasma discharges were produced at low pressure by a large volume device. The directly plasma-exposed spore...

In recent years, tulip flowers have been grown extensively in parks and green spaces of Urmia city (NW Iran). During the surveys in a period from 2014–16, characteristic symptoms of the blue mold rot were observed on both planted and stored tulip bulbs, as the bulbs were covered with a white to bluish-green mycelia and spores. In order to determine the fungi associated with tulip bulbs (Tulipa ...
