Gene structures of grape glyoxalase genes and domain architectures of grape glyoxalase proteins. The exons are represented by black boxes while the introns are represented by black lines. Only the exons are drawn to scale because some introns are too long. The glyoxalase domain (PF00903) of VvGLYI-like is represented by an orange box. For VvGLYII-like proteins, β-lactamase domain is represented by a blue box and the hydroxyacylglutathione hydrolase C-terminus (HAGH-C) domain is represented by an orange hexagon. The DJ/Pfpl domain (PF01965) of VvGLYIII-like protein is represented by a dark green box. The domain position is indicated by the number inside the box or hexagon. The full length of protein is indicated by the numbers at both ends
