Occurrence of Anthracnose on Welsh Onion Caused by Colletotrichum circinans
Anthracnose occurred frequently on leaf sheaths of Welsh onions grown in Gangwha island, Korea in November, 2007. The disease incidence was as high as 30% in five fields investigated. A total of 20 single spore isolates of Colletotrichum species were obtained from the affected plants, and all the isolates were identified as Colletotrichum circinans based on their morphological and cultural char...
متن کاملSuppressive Effects of Welsh Onion Extracts on Mucus Hyper-Production in Human Airway Cells
We investigated the suppressive effects of Welsh onion (Allium fistulosum L.) on the hyper-production of mucins in NCI-H292 human lung cancer cells. Periodic acid-Schiff staining showed that the 50% (v/v) ethanol extract of Welsh onion suppressed mucus glycoprotein production in cells, whereas the water and ethanol extracts did not. A real-time RT-PCR analysis demonstrated that the 50% ethanol ...
متن کاملThe degradation of onion cell walls by extracellular enzymes of Botrytis allii and Sclerotium cepivorum [proceedings].
Botrytis allii and Sclerotium cepivorum, which respectively cause neck rot and white rot of onions, produce a range of cell-wall-degrading enzymes in onion tissue (Hancock et al., 1964; Beck, 1976). The two fungi have been grown on liquid media using purified onion cell walls, prepared by an adaptation of the method of Jarvis et al. (1977), as the sole carbon source for B. allii and the major c...
متن کاملUltrastructural and molecular studies on fat and thin macrocysts of Sarcocystis spp. isolated from naturally infected goats
There is considerable confusion concerning the structure and synonymity of macroscopic sarcocysts in goats. In the present work, ultrastructural and molecular study on fat and thin macrocysts of Sarcocystis isolated from naturally infected goats were investigated. Two forms of macrocystic sarcocysts were collected from fresh oesophagus, diaphragm, skeletal muscles and heart of slaughtered goats...
