There are at least 2 amino pools for leucine and for valine in the soybean hypocotyl, a small protein precursor pool and a large inactive pool. The precursor pool decreased in size during incubation of excised hypocotyls presumably because the cotyledonary sources of amino acids had been removed. The precursor pool was subject to expansion by supplying the amino acid externally at high concentrations. After the transfer of tissue to unsupplemented media, the expanded pool was rapidly depleted.
在大豆下胚轴中,至少有 2 个亮氨酸和缬氨酸的氨基酸库,一个是小的蛋白质前体库,另一个是大的无活性库。在离体下胚轴的孵育过程中,前体库的大小减小,可能是因为已经去除了子叶来源的氨基酸。通过在高浓度下外部供应氨基酸,可以使前体库扩大。将组织转移到未补充的培养基后,扩大的库迅速耗尽。
