The present invention relates to the genetic engineering of higher plants to confer chilling resistance. Provided is a higher plant which contains more unsaturated fatty acids in membrane lipids than are inherent to that plant species, and a process for producing the same. A preferred embodiment of the plant is a transgenic plant expressing a polypeptide with a glycerol 3-phosphate acyltransferase activity that has a higher substrate selectivity for oleoyl-(aryl-carrier-protein) (oleoyl-ACP) than for palmitoyl-(aryl-carrier-protein) (palmitoyl-ACP). In another aspect, there are provided higher plants with a lowered critical temperature for chilling injury, and a process to produce the same. A preferred embodiment of the plant is a transgenic plant whose phosphatidylglycerol contains reduced amounts of saturated molecular species due to the expression of a polypeptide with a glycerol 3-phosphate acyltransferase activity that has a higher substrate selectivity for oleoyl-ACP than for palmitoyl-ACP.
