Ralstonia solanacearum strain FQY_4 was isolated from a bacterial wilt nursery, which is used for breeding crops for Ralstonia resistance in China. Here, we report the complete genome sequence of FQY_4 and its comparison with other published R. solanacearum genomes, especially with the strains GMI1000 and Y45 in the same group.

Gram-negative bacterial pathogens inject effector proteins inside plant cells using a type III secretion system. These effectors manipulate plant cellular functions and suppress the plant immune system in order to promote bacterial proliferation. Despite the fact that bacterial effectors are exogenous threatening proteins potentially exposed to the protein degradation systems inside plant cells, effectors are relative stable and able to perform their virulence functions.

CprA is a short-chain dehydrogenase/reductase (SDR) that contributes to resistance against colistin and antimicrobial peptides. The cprA gene is conserved across Pseudomonas aeruginosa clades and its expression is directly regulated by the two-component system PmrAB. We have shown that cprA expression leads to the production of outer membrane vesicles (OMVs) that block autophagic flux and have a greater capacity to activate the non-canonical inflammasome pathway.

Ginger (Zingiber officinale) is an herbaceous perennial in the Zingiberaceae family grown primarily in tropical to subtropical biomes as a culinary spice, a traditional medicine, and a landscaping plant. While ginger grows at soil temperatures above 20°C, several farmers in the upper Midwestern US farmers grows short-season ginger in high tunnels. In 2023 and 2024, growers in southeastern Minnesota reported a new disease of ginger.

For plant diseases to become established, plant pathogens require not only virulence factors and susceptible hosts, but also optimal environmental conditions. The accumulation of high soil salinity can have serious impacts on agro-biological ecosystems. However, the interactions between plant pathogens and salinity have not been fully characterized.

The Ralstonia solanacearum Species Complex (RSSC) is the most significant plant pathogen group with a wide host range. It is genetically related but displays distinct biological features, such as restrictive geography occurrence. The RSSC comprises three species: Ralstonia pseudosolanacearum (phylotype I and III), Ralstonia solanacearum (phylotype IIA and IIB), and Ralstonia syzygii (phylotype IV) (Fegan and Prior 2005).
