Fig. 5From: Genome-wide association study (GWAS) reveals the genetic architecture of four husk traits in maizeHeat-map of tissue-specific expression patterns of candidate genes identified by GWAS. The values used in the figure are the log2 transformed ratio of normalized PRKM count in husk relative to that in other tissues as shown at the bottom of each column. Columns and rows are ordered according to similarity (hierarchical cluster analysis at the top and left). The orange, white, and blue represent higher in husk than other tissues, close to other tissues, and lower than other tissues of a particular gene, respectivelyBack to article page
