Pectobacterium atrosepticum G/39, G39

Pectobacterium atrosepticum G/39, also referred to as G39, is a Gram-negative, anaerobic bacterium characterized by its rod shape and mobility, facilitated by the presence of flagella. This mesophilic organism thrives optimally at a temperature of 27°C and can grow within a specific temperature range suitable for mesophiles. Notably, G39 possesses two replicons, indicating a complex genetic architecture. Pectobacterium atrosepticum is known for its free-living biotic relationship, primarily affecting a variety of host plants. These include Solanum tuberosum (potato), Daucus carota (carrot), Beta vulgaris subsp. vulgaris (beet), Cynara cardunculus var. scolymus (globe artichoke), and Cichorium intybus (endive). The bacterium is associated with soft rot, a significant plant disease that leads to tissue decay and economic losses in agricultural practices. The presence of G39 in such a diverse range of hosts underscores its ecological versatility and potential impact on crop health and yield. Understanding the traits of Pectobacterium atrosepticum, particularly its pathogenicity and environmental adaptability, is crucial for developing effective management strategies against soft rot in affected crops. The accessions CP036163.1 and CP036162.1 provide valuable genomic resources for further research into its biology and interactions with host plants.
