The protein accumulates ubiquitin and is sent to the proteosome which has proteases that degrade the protein to its amino acids. The Rub pathway is similar to the ubiquitin pathway but is not involved in degradation. This pathway functions to modify the E3-scf directly, and without this pathway, there is no auxin response. The systemin signaling pathway alters the lipid composition of membranes and this change leads to the production of an agent that influences the systemin pathway. MJ induces an increase in receptors for systemin, thus increasing the sensitivity of tissues to systemin.
Insect feeding on plants or injury to plant tissue induces the systemin signaling pathway.
This pathway leads to the production of methyl jasmonate, a volatile signaling molecule that can induce defense responses in plants near to, but distinct from the plant being attacked by insects, thus making those plants more resistant to insect attack. These wasps lay eggs in the bodies of the army worms, and the larvae that hatch from these eggs consume the host worms. A commonly presented argument against genetically engineered plants is that the scientific community has no prior experience moving genes around and so it cannot really predict whether these manipulations will have deleterious side effects. Present a case for and against this argument. There is no conclusive evidence or convincing rationale for believing that the current methods of genetically manipulating crop plants, which are more directed and efficient, will lead to any more deleterious effects than the hybrid crops produced by traditional breeding methods did.
