Figure 2.

Domain structure of the deduced amino acid sequences of the wheat PDI and PDI-like genes. When multiple putative homoeologous cDNA sequences were identified, the domain structure reported in the figure is relative to the cDNA sequence identified by the letter a. The putative signal peptides (SP), the a and b type domains, the N-terminal acidic domains (E + D), the D domains (Erp29c), the transmembrane domains (TM) and the DUF domain of TaPDIL8-1 are reported. The thioredoxin-like catalytic site tetra-peptides and the C-terminal tetra peptides are also reported. Numbers above indicate domain boundaries (aa) numbers on the right ORF (aa).
