Claudine Boyer et al. present novel genomic data for #Xanthomonas citri pv. bilvae, the causal agent of bacterial shot-hole disease in bael trees. Learn more: https://doi.org/10.1094/PHYTO-07-25-0255-SC

FIGURE 1 Chemotaxis in Xanthomonas: Chemo-attractants and repellents present in the micro-environment of host exudates bind to the chemoreceptors (Mcp) present in the inner membrane of Xanthomonas. Based on binding, CheA is recruited by CheW and auto-phosphorylation happens. CheR and CheB drive methylation and demethylation events, respectively. CheY and CheB are phosphorylated as response regulators. Phosphorylated CheY regulates flagella-mediated clockwise rotation (CR). Phosphorylated CheB turns off kinase activity of CheA through demethylation, inhibits phosphorylation of CheY, and regulates flagella-mediated counterclockwise rotation (CCR).

Arkaprabha China et al. discuss recent advances in understanding how #Xanthomonas integrates environmental and host-derived signals to regulate its pathogenicity. Read the open access review in #Phytopathology: https://doi.org/10.1094/PHYTO-05-25-0183-RVW

M: 50 bp DNA ladder; L0: positive control (X. fragariae W2L gDNA); L1 to L5: 1 d, 2 d, 3 d, 4 d, and 5 d; L6: normal leaf; L7: ddH2O. B, PCR detection of X. fragariae in naturally infected strawberry plants from farms. M: 50 bp DNA ladder; L1 to L4: infected leaves from four strawberry plants; L5: positive control (X. fragariae W2L gDNA); L6: ddH2O. Genomic DNA from the infected leaves (L1 to L6 in A and L1 to L4 in B) was extracted using the TIANGEN Plant Genomic DNA Extraction Kit according to the manufacturer’s instructions.
