Fig. 3From: Identification and expression analysis of GRAS transcription factors in the wild relative of sweet potato Ipomoea trifidaGene structure of GRAS members in I. trifida. The phylogenetic tree of ItfGRAS genes is shown on the left, which was divided into 11 clusters, including PAT1, SHR, SCL4/7, LAS, SCR, Os19, DELLA, DLT, SCL3, LISCL and HAM. Schematic diagram of exon/intron structure was displayed by the gene structure display server (GSDS) (http://gsds.cbi.pku.edu.cn/). The exons, introns and UTR are represented by red solid boxes, black lines and blue boxes, respectivelyBack to article page
