Figure 6.

Proteic alignment of 15 RipAX2 alleles (of 19) identified within the world Ralstonia solanacearum species complex (RSSC) collection. Each allele number is linked to its representative strain and to the number of strains in which it was found. Proteic sequences were aligned (MUSCLE with default settings) and clustered using the FastTree method, with optimization of the Gamma20 likelihood at 20 rate categories of sites. The zinc (Zn)‐binding motif (HEXXH) described by Nahar et al. (2014) is marked by dark shading (positions 152–158). The effector sequence is considered to be non‐functional (NF) if its length is less than 80% of the GMI1000 reference sequence (219 amino acids).
