Phylogenetic analysis of the proteins of the GRAS gene family. The phylogenetic tree was constructed using MEGA 5.0 with the maximum likelihood method using 1000 replicate bootstrap tests. Numbers near to the nodes indicate bootstrap values obtained from 1000 replications. The 51 proteins were clustered into eight distinct groups: SCL9, PAT1, LAS/SCL18, SCL4/7, SHR, SCR, HAM and DELLA, as indicated. At, Arabidopsis thaliana; Os, Oryza sativa; Gm, Glycine max; Pe, Populus; Pr, Pinus radiata; Pt, Pinus taeda; La, Lupinus albus; Ps, Pisum sativum; Cs, Cucumis sativa; Zm, Zea mays; Psy, Pinus sylvestris.
