TYQ1 Nematode Biocontrol SynCom

Community ID CommunityMech:000072
Ecological State ENGINEERED
Environment cucumber rhizosphere
ENVO:00005801

An 8-member synthetic community centered on keystone species Rhizobium pusense TYQ1, which is enriched during root-knot nematode (Meloidogyne incognita) infection of cucumber (Cucumis sativus cv. Zhongnong 26). TYQ1 recruits 7 biomarker species that enhance biofilm formation and metabolic cross-feeding, creating a tightly interconnected network for synergistic nematode suppression. The community was identified through stress-induced enrichment analysis and validated across 12 soil types, demonstrating that keystone species recruitment can guide functional microbial community assembly to synergistically enhance plant health.
