Abstract

Abstract Quantum biological effects are increasingly implicated in rapid adaptive processes; however, their mechanistic role in pollinator genomic regulation remains unresolved. This study develops a multiscale quantum–biophysical framework to quantify proton tunneling and tautomeric genomic shifts in Apis mellifera and Apis cerana within the agroecological gradients of Chattogram, Bangladesh 22.47°N, 91.79°E, and the Sitakunda Hill Range. Using density functional theory at the B3LYP/6-311G (d, p) level, combined with QM/MM simulations and ring polymer molecular dynamics, we identify a stable proton transfer barrier of 28.60 kcal/mol and demonstrate quantum enhancement factors (κ) up to 9.75 × 10⁸ with rate constants approaching 49.90 s⁻¹ under thermal conditions of 35°C. Kinetic isotope effects exceeding 635 confirm dominant tunneling regimes, while decoherence modeling reveals sustained coherence times τₙ ≈ 2.42–2.59 s, supporting the existence of an intrinsic DNA “Faraday cage” effect. Transcriptional simulations indicate a reduction in activation energy from 28.6 kcal/mol to 4.3 kcal/mol (≈ 85%), enabling rapid non-enzymatic activation of immune genes such as defensin and abaecin. Stochastic modeling further shows tunneling probabilities increasing from 0.067 to 0.50 under elevated ROS flux, linking subatomic dynamics to adaptive phenotypic plasticity. Comparative analysis demonstrates that Apis cerana exhibits lower noise sensitivity and higher coherence stability (r² =…
