Cv. Xushu 18 and via immunogold electron-microscopy technique, showed that β-amylase visualized by gold particles was predominantly localized in plastids especially at periphery of starch granules, but the gold particles were scarcely found in other subcellular compartments, indicating that the enzyme is subcellularly compartmented in the same zone as its starch substrates.

本研究利用胶体金免疫电镜定位技术证明，甘薯块根生活细胞中的β-淀粉酶也是主要定位于质体内，围绕淀粉粒分布较多，其他亚细胞区域内β-淀粉酶分布很少，说明该酶主要分布于其功能区域。
