Abstract

genes but downregulated amino acid biosynthesis and non-essential pathways, indicating metabolic resource reallocation. Concurrently, host transcriptomics revealed a shift from symbiont-dependent strategies ("farming" and "milking") to filter-feeding and extracellular matrix remodeling, indicating changes in trophic level. This dynamic interplay demonstrates how the holobiont balances symbiont maintenance with alternative energy acquisition under stress and highlights the vulnerability of chemosynthetic symbioses to methane fluctuations induced by environmental changes.
