Parasitic castration of plants by fungi.
If the production of genetically variable offspring is a mechanism of host defense against parasites, then parasites capable of suppressing sexual reproduction in hosts may gain a selective advantage over parasites that do not do so. Recent work has shown that a range of systemic fungi infecting plants sterilize their hosts, effectively preventing coevolutionary responses by host populations to...
متن کاملAnti-parasitic Activity of Certain Indigeous Plants
The antiparasitic activity of certain indigenous plant extracts was tested against the model bovine filarial parasite Setaria digitata. Among the plants tested, the extracts of Strebulus asper was found to be most effective. The chloroform and other phase of the organic solvents showed most activity indicating that the active compound may be a non polar substance having low molecular weight.
متن کاملRhizosphere communication of plants, parasitic plants and AM fungi.
Plants use an array of secondary metabolites to defend themselves against harmful organisms and to attract others that are beneficial. However, the attraction of beneficial organisms could also lead to abuse by malevolent organisms. An exciting example of such abuse is the relationship between plants, beneficial mutualistic arbuscular mycorrhizal fungi and harmful parasitic plants. Signalling m...
متن کاملPossible fungistatic implications of betulin presence in betulaceae plants and their hymenochaetaceae parasitic fungi.
Betulin and its derivatives (especially betulinic acid) are known to possess very interesting prospects for their application in medicine, cosmetics and as bioactive agents in pharmaceutical industry. Usually betulin is obtained by extraction from the outer layer of a birch bark. In this work we describe a simple method of betulin isolation from bark of various species of Betulaceae trees and p...
متن کاملEndophytic insect-parasitic fungi translocate nitrogen directly from insects to plants.
Most plants obtain nitrogen through nitrogen-fixing bacteria and microbial decomposition of plant and animal material. Many vascular plants are able to form close symbiotic associations with endophytic fungi. Metarhizium is a common plant endophyte found in a large number of ecosystems. This abundant soil fungus is also a pathogen to a large number of insects, which are a source of nitrogen. It...
