The phylogenetic tree analysis was constructed with MEGA 5.2 software using the neighbor-joining method and the following parameters: bootstrap analysis of 1000 replicates, poisson model and pairwise deletion. The numbers at the nodes indicate the bootstrap values. SlDEAD30 and SlDEAD31 are marked with a black triangle and a red triangle, respectively. Accession numbers and corresponding references for the proteins used are as follows: Solanum lycopersicum: SlDEAD30, KJ739798; SlDEAD31, KJ713393.
