Ecological adaptations influence the susceptibility of plants in the genus Zantedeschia to soft rot Pectobacterium spp.

Soft rot disease caused by Pectobacterium spp. is responsible for severe agricultural losses in potato, vegetables, and ornamentals. The genus Zantedeschia includes two botanical groups of tuberous ornamental flowers that are highly susceptible to the disease.

Host Specificity and Differential Pathogenicity of Strains from Dicot and Monocot Hosts.

Recent phylogenetic studies have transferred certain isolates from monocot plants previously included in the heterogeneous group of (Pc) to a species level termed . The specificity of associated infections had received less attention, and may be of high scientific and economic importance. Here, we have characterized differential responses of isolates from potato (WPP14) and calla lily (PC16) on two typical hosts: var.
