Clustering of selected out genes expression profiles at 6 different comparison. Expression ratios are expressed as log 2 values. Number 1 to 6 indicated expression ratios of yongan2hao/daye3bianzhong, yongan3hao/daye3bianzhong, yongan4hao/daye3bianzhong, yongan2hao/yongan1hao, yongan3hao/yongan1hao, yongan4hao/yongan1hao, respectively. Red color represents increasing level of the gene expression and green color indicates decreasion of the gene expression after challenging with control samples. Arrow showed the genes that expression ratios absolute values > 10 among six comparison groups.
