A Nematode Teaches Us Something About The Evolution Of Parasites

Scientists have decoded the genome of the Pristionchus pacificus nematode and gained valuable insight into the evolution of parasitism. In their work, the scientists have shown that the genome of the nematode consists of a surprisingly large number of genes, some of which have unexpected functions. These include a number of genes that are helpful in breaking down harmful substances and for survival in a strange habitat: the Pristionchus uses beetles as a hideout and as means of transport, and feeds on the fungi and bacteria that spread out on their carcasses once they have died. It thus provides the clue to understanding the complex interactions between host and parasite. Read More...
