PREMISE Sparse understory communities, in association with non-native tree species, are often attributed to allelopathy, the chemical inhibition of a plant by another. However, allelopathy is difficult ecological phenomenon demonstrate as many studies show conflicting results. Eucalyptus globulus, native Australia, one most widely planted trees around world. understories common beneath E. globu...

The effect of allelopathy in the joint germination winter soft wheat with alfalfa changeable and galega orientalis is studied. influence on indicators early growth processes vice versa was evaluated. In experiment alfalfa, laboratory root length decreased by 4-21% 3-10%, number roots sprout increased to 22% 8-29%, respectively. galega, germination, 7-15%, 7-16% 4-6%, incidence fungal diseases s...

Natural products involved in plant-plant and plant-microorganism ecological interaction (Allelochemicals) are an important potential source for alternative agrochemicals and pharmaceuticals, in order to solve the many problems derived from inadequate culture practices and abuse of synthetic herbicides. Isolation, structural determination, bioassay techniques and applicability for these compound...

Microbes produce a variety of compounds that are used to kill or suppress other species. Traditional antibiotics have their origins in these natural products, as do many types of compounds being pursued today in the quest for new antibacterial drugs. When a potential toxin can be encoded by and exported from a species that is not harmed, the opportunity exists to use directed evolution to impro...
