Abstract
When corn (Zea mays) roots are supplied with high concentrations of unlabeled myoinositol, the conversion of d-glucose-6-(14)C to cell wall galacturonic acid is significantly reduced compared to controls, although its incorporation into cell wall glucosyl units remains unchanged. This suggests that, in order to be converted to uronic acid, radiolabel from glucose must first pass through the internal myoinositol pool of the roots.
摘要
当给玉米（玉蜀黍）根提供高浓度的未标记肌醇时，与对照相比，D-葡萄糖-6-（14）C向细胞壁半乳糖醛酸的转化显著降低，尽管其掺入细胞壁葡糖基单位的量保持不变。这表明，为了转化为糖醛酸，来自葡萄糖的放射性标记必须首先通过根的内部肌醇池。
