Figure 7From: Evolution of plant senescenceStructures and phylogenies of Clostridium Sgr proteins. (a) Comparison of Sgr structures in representative plant and Firmicute genera by BLASTP alignment. Shading density indicates % sequence similarity: black = 100%; dark grey = 80%; light grey = 60%. (b) Unrooted tree of phylogenetic relationships between Clostridium spp based on sequence alignments of ribosomal RNA [71, 72]. (c) Protein tree of Sgr-like sequences from clostridia.Back to article page
