Phylogenetic tree of grass Hsf genes and the synteny of each OGC. (a) Phylogetic tree of 123 grass Hsf genes. The numbers above the branches indicate the maximum-likelihood, neighbor-joining and maximum parsimony bootstrap values. Asterisks indicate values smaller than 50%. The genes in the box are formed through a tandem duplication event. (b) Syntenic analysis for each grass Hsf OGC. Five protein-coding genes upstream and downstream of each Hsf gene are shown by depicted by colored polygons. The Hsf genes are shown by grey polygons. The polygons with the same color in a OGC are the homologs.
