One aspect of several parasitic groups that reflects this is their metabolic organelles, mitochondria and plastids. These organelles are derived from endosymbiosis with an alpha-proteo...

An exciting example of such abuse is the relationship between plants, beneficial mutualistic arbuscular mycorrhizal fungi and harmful parasitic plants. Signalling m...
متن کاملSTUDIES OF PARASITIC FUNGI ON THE CANE PEST MUlR
Nurnicia viridis Muir, otherwise known as the green leaf-sucker, is an important pest of sugarcane in South Africa (Anon.',"; Dick). It is capable of causing considerable damage to this crop and has therefore been the subject of repeated pest population surveys. Studies of its life history, pest-host plant-relationships and means of biological control, are all currently receiving considerable a...
