INTRODUCTION 3-Deoxy-d-manno-oct-2-ulosonic acid (KDO) is an eight-carbon sugar acid found in Gram-negative bacteria and vascular plants. In plants, KDO occurs as a residue of rhamnogalacturonan II (RG-II), a domain of pectin in the primary cell wall (York et al., 1985). RG-II forms a dimer, being cross-linked with boric acid (Kobayashi et al., 1996; O'Neill et al., 1996), thereby binding pectin macromolecules to form a hydrophilic gel that surrounds cellulose microfibrils.

Abstract To address the diminishing marginal effects of government subsidies and the lack of regulatory synergy in agricultural green supply chains, this study divides revenue heterogeneity into five representative scenarios: subsidy-dependent, regulation-driven, self-motivated, externally constrained, and subsidy-withdrawal, and develops a multi-scenario evolutionary game model involving two agents: the government (incentive/non-incentive) and agricultural entities (high-effort/low-effort).
