Figure 2. Multiple alignments of the amino acid sequences of SbPSY with other PSYs. Identical residues are indicated by a black background, and similar residues are shaded with a gray background. The solid underline is the trans-IPPS-HH domain. DXXXD, where X encodes for any amino acid, represents the aspartate-rich region. NtPSY2, Nicotiana tabacum (JX101474); CcPSY, Coffea canephora (DQ157164); SlPSY2, Solanum lycopersicum (NM_001247742); PtPSY, Populus trichocarpa (XM_002327528).
