Fig. 1From: Genome-wide identification and expression profiling of DREB genes in Saccharum spontaneumPhylogenetic tree of DREB1 and DREB2 genes in S. spontaneum (red), sorghum (black), maize (cyan), rice (blue), and Arabidopsis (green). The phylogenetic tree was constructed based on the full-length sequence alignments of 97 DREB proteins from five species. Red and blue arcs indicate the DREB1-type and DREB2-type genes, respectivelyBack to article page
