Background It is becoming increasingly clear that stress and metabolic signalling networks interact and that this interaction is important in plant responses to herbivory, pathogen attack, drought, cold, heat and osmotic stresses including salinity. At the interface between these two major signalling systems are the hormone abscisic acid (ABA) and signalling factors including protein kinases an…

This article gives some examples of these novel GM crops and summarizes the conclusions of a report …
