Perturbation without collapse: multi-layer buffering in the oil palm root microbiome under basal stem rot

This thesis presents the first dual-resolution metagenomics analysis of oil palm root microbiomes, integrating community-level coassembly profiling with genome-resolved MAG analysis across three root compartments and two health states. Compartment dominance overwhelmingly exceeds disease as the organizing principle, with BSR manifesting as a distributed functional perturbation rather than wholesale community collapse.
