Freezing Plant Responses Abiotic Stress  Preventing Dec Temp

Front Plant responses to abiotic stress - Preventing freezing
Back
  • dec temp can freeze cells, distrupt membrane and kill them
  • cyto and sap in vacuoles evolved solutes which lower freezing point, and AA, PS, sugars, proteins act as antifreeze, some species only form these frost resistent chemicals in winter (diff genes suppressed/activated once sustained fall/rise in temps and day lengths)
