When will freezing tolerance be targeted by gene mapping in plant breeding programmes?
Freezing down on the farm; Low temperatures and production Low temperature responses of crops are a complex network of physiological and biochemical events that if clarified could provide indicators for the selection of cold or freezing resistance. Cold and freezing tolerance is achieved in crops by cold acclimation processes. This involves several different types of metabolic events. Reduced water content associated with freezing can produce a range of osmotic effects and the potential metabolic messages produced can result in acclimation. The low temperature story shows agronomists that relating environmental events to specific metabolic events is practically impossible. Agronomists have traditionally treated management by looking at whole plant responses by observation alone. We are now moving to a system of management that works at a metabolic (proteome) and genome level. How these new styles of analysis are integrated into agronomy is demonstated by studies on low temperature resi
