Cottonmouth (Agkistrodon piscivorus leucostoma) testes were examined histologically to determine the germ cell development strategy employed during spermatogenesis. Testicular tissues from Cottonmouths were collected monthly from swamps around Hammond, Louisiana. Pieces of testis were fixed in Trump's fixative, dehydrated in ethanol, embedded in Spurr's plastic, sectioned with an ultramicrotome...

Grapevine (Vitis vinifera L.) is one of the most prevalent and long-standing cultivated crops in world due to its non-selective climate soil demands, types usage having a wide range varieties. Turkey has rich grapevine gene pool because favorable zone. Viticulture, which an important role agriculture, faces many problems process production marketing. Fungal diseases take place by limiting where...

Abstract Phytopathogens secrete numerous effectors that facilitate their infection and colonization processes. However, the pathogenic mechanism of in Cytospora chrysosperma , causal agent canker disease many woody plants, remains poorly understood. In this study, we identified five glycoside hydrolase family 12 (GH12) effector genes C. genome, all which were significantly upregulated during st...

We describe a case in which a patient immunocompromised by acute myeloid leukemia experienced acute fulminating invasive fungal sinusitis followed by pneumonia and then death. Though the microbiology of the pneumonia could not be directly investigated, nasal lesions revealed fungal mycelium. Valsa sordida was consistently cultured from a biopsied sample. The fungus was identified to the genus l...

BACKGROUND BACE1 was found to be the major β-secretase in neurons and its appearance and activity were found to be elevated in the brains of AD patients. Fungal endophytic extracts for BACE1 inhibitory activity and cytotoxicity against PC-12 (a rat pheochromocytoma with neuronal properties) and WRL68 (a non-tumorigenic human hepatic) were investigated. METHODS Endophytes were isolated from pl...

BACKGROUND The plant pathogenic fungus (such as Gibberella zeae, Fusarium oxysporum and Cytospora mandshurica) causes devastating disease in agriculture. The pathogenic fungus is responsible for billions of dollars in economic losses worldwide each year. In order to discover new fungicidal molecule with good fungicidal activity against G. zeae, F. oxysporum, and C. mandshurica, we sought to com...

A series of novel sulfone derivatives containing 1,3,4-oxadiazole moiety were synthesized. All the target com-pounds were characterized by H and C nuclear magnetic resonance, infrared spectroscopy and elemental analysis. Their antifungal activities were tested in vitro with six important phytopathogenic fungi, namely, Gibberella zeae, Fusarium oxysporum, Cytospora mandshurica, Phytophthora infe...
