Recently, species clustering within has been identified as complex, encompassing validly published names, including and , with some strains potentially delineating new species. In this study, genomes of strains isolated from a bacterial heart rot outbreak in pineapple ( var. ) on Oahu, Hawaii, along with two strains from pineapple in Malaysia, were sequenced.

and are closely related genera in the family Lysobacteraceae. In our previous study of aroid-associated bacterial strains, most strains isolated from anthurium and other aroids were reclassified as and other species. However, two strains isolated from and were phylogenetically distant from other strains in the clade and two strains isolated from clustered within the clade.

The family Araceae, comprising ornamentals including , , , , and , is susceptible to pathogens. Previous analyses have established heterogeneity in aroid strains, yet unresolved taxonomic positions and dynamics between and frequently associated in aroids necessitate in-depth genetic investigation to resolve these complex relationships. This study utilized multilocus sequence analysis of housekeeping genes , , , , and to investigate 59 aroid strains, selected based on hosts, time, and geographical origins.

Dickeya fangzhongdai, a bacterial pathogen of taro (Colocasia esculenta), onion (Allium sp.), and several species in the orchid family (Orchidaceae) causes soft rot and bleeding canker diseases. No field-deployable diagnostic tool is available for specific detection of this pathogen in different plant tissues.
