Fig. 3From: Genome-wide identification and characterization of small auxin-up RNA (SAUR) gene family in plants: evolution and expression profiles during normal growth and stress responseSequence analysis and structure prediction of SAUR proteins in clade 2. a Multiple sequence alignment of SAUR proteins in clade 2 using Clustal Omega. Some nonconserved insertions of a few SAUR members were removed from the alignment. The dashed grey lines represented vacant sites (no amino acid residues) in multiple sequences alignment. The region of the SAUR domain was labeled in a black box. b The predicted tertiary structure of AtSAUR8 and OsSAUR8 using conserved domain onlyBack to article page
