Table 2: Main characteristics of the genome of _P. aroidearum_ SM2. Figure 3: Count of subsystems by category. Annotation of the various primordial metabolic processes of the _P. aroidearum_ strain SM2. However, when the AMR phenotype was tested, the results showed resistance only to erythromycinycin, while sensitivity was observed for ampicillin, cephalothin, cefotaxime, ciprofloxacin, clindamycin, dicloxacillin, gentamicin, penicillin, tetracycline, sulfamethoxazole/trimethoprim, vancomycincin, amikacin, carbenicillin, chloramphenicol, netilmicin, and nitrofurantoin. These results demonstrate the importance of antibiotic resistance phenotype assays versus genotype annotation for genome analysis. The virulence genes were predicted using Victors, PATRIC, and VFDB sources, which are important databases for predicting pathogenicity. In the Victors database, a total of 81 virulence genes were detected; from the PATRIC database, we obtained a total of 49 virulence genes, and in the VFDB database, we detected a total of 17 virulence genes. Furthermore, we searched for relevant genes encoding plant-cell-wall-degrading enzymes (PCDEWs), toxins, and secretion systems for _P. aroidearum_ SM2 (Table 3). We found 12 genes that encode PCDEWs. Also, we discovered 139 genes involved in five types of secretion systems: 22 genes in type I (TISS), 22 genes in type II (T2 SS), 40 genes in type III (T3 SS), 19 genes in type IV (T4 SS), none in type V (T5 SS), and 20 genes in type VI (T6 SS). On the other hand, 16 genes were related to invasion motility. Figure 4: Antibiotic resistance genes. The AMR mechanism and its related genes are indicated with color diagrams. According to the phylogenetic tree (Figure 5), _P. aroidearum_ SM2 matches with the clade that includes _P. aroidearum_ strain MY2, which was isolated from _Amorphophallus konjac_ in China, as well as with _P. aroidearum_ L6 isolated from the soft rot of _S. podophyllum_ in Hainan province, China. It also matches with the _P. aroidearum_ strain MY11 isolated from a tuber (_Amorphophallus konjac_) from Sichuan province, China. The ANI values confirmed these phylogenetic analyses (Supplementary results, Table S1). The pairwise genome comparison of _P. aroidearum_ SM2 showed ANI values of 97.30% with _P. aroidearum_ L6 and 97.25% with _P. aroidearum_ QJ002. Therefore, the genome of _P. aroidearum_ SM2 is of great relevance to understanding soft rot in the fruits of chili and tomato, as well as in potato tubers, in the Mexican context, as these are crops of economic importance.
