Maintenance of Gut Microbial Balance via the Kynurenine Pathway Improves Larval Performance and Resistance to Bacillus thuringiensis in Spodoptera exigua. [PDF]
MicrobiologyopenCRISPR/Cas9‐mediated deletion of kmo in Spodoptera exigua abolished 8‐HQA production, disrupted gut microbial homeostasis, and promoted Enterococcus dominance in gut and oral secretion. Mutants exhibited impaired growth, delayed development, and increased susceptibility to Bacillus thuringiensis, highlighting a conserved role of the kynurenine pathway ...
