Recognition of Agrobaterium by the plant
“To initiate the tumorous state, cells of Agrobacterium must first attach to a wound site on the plant. Molecular evidence suggests that the recognition of Agrobacterium by plant tissue involves complementary receptor molecules on the surfaces of the bacterial and plant cells. It is though that the plant receptor molecule is a type of pectin and that the bacterial receptor is a type of plysaccaride containing Beta-glucans.”
