Fungi are eukaryotic organisms, like plants and animals. Unlike plants, they don't performphotosynthesisand they have chitin, a derivative of glucose, in their cell walls. Like animals, fungi areheterotrophs, which means they get their nutrients by absorbing them. Although most people think one d...
SUBSTANCE: plant fungicide has two biologically active components. The first (I) component is 1-[3-(tert. -butylphenyl)-2-methylpropyl] -piperidine, 4-(2,2- -difluoro-1,3-benzodioxol-4-yl)-1H-pyrrole-3-carbonitrile or N-(trichloromethylthio)-cyclohex-4-ene-1,2-dicarboximide. The ...

Fungal cells are of two basic morphological types: true hyphae (multicellular filamentous fungi) or the yeasts (unicellular fungi), which make pseudohyphae. A fungal cell has a true nucleus, internal cell structures, and a cell wall. The success of fungi in colonizing terrestrial ecosystems can ...
For successful virulence, pathogenic fungi must counteract a plethora of host-specific factors, such as serum and immune cells in animals, and plant hormones, fatty acids and hard mechanical surface in plants. Signalling pathways that are responsible for the fungus–host interaction include the cAMP...
Ergo line alkaloids in convolvulaceous host plants originate from epibiotic clavicipitaceous fungi of the genus Periglandula Ergoline (i.e., ergot) alkaloids are a group of physiologically active natural products occurring in the taxonomically unrelated fungal and plant taxa, Cla... Steiner,Leist...
