Cold and drought are major factors reducing the yield and geographical distribution of most horticultural crops worldwide. Both cold and drought are lead to decreasing of water potential of plant tissues and induce ROS accumulation causing severe damage to various cellular components such as altering membrane lipid composition due to excess accumulation of malondialdehyde (MDA), structural proteins and enzymes. Plant responses to the stresses are complex and complicated especially in perennial woody crops and hundreds of genes are involved. To develop cultivars tolerant to both cold and drought it is necessary to find genes involved in both stress-tolerance to develop genetic markers.
