This communication reviews recent biochemical studies ofL-canavanine that have provided significant understanding of the interaction between the seed ofDioclea megacarpa (Leguminosae) and the bruchid beetleCaryedes brasiliensis (Bruchidae). The principal biochemical bases are proposed for: canavanine toxicity, the ability of the beetle larvae to adapt to its presence, the metabolic sequestration and detoxification of ammonia, and the potential amplification by microbial symbionts of the beetle's abilities to adapt to toxic components of the host.
本通讯综述了 L--canavanine 的近期生化研究进展，这些研究为理解 Dioclea megacarpa（豆科）种子与 Caryedes brasiliensis（豆象科）甲虫之间的相互作用提供了重要的认识。本文提出了以下主要生化基础：canavanine 毒性、甲虫幼虫适应其存在的能力、氨的代谢隔离和解毒、以及微生物共生体对甲虫适应宿主有毒成分的能力的潜在放大。
