Abstract
The degradation of phytin in germinating mung bean seeds has been found to be associated with the increased activity of phytase in the cotyledon. In the differentiated embryo the increase of this activity is very low all throughout the growth periods studied. Phytase appears in the cotyledon during germination. No activity has been detected in the cotyledons of unsoaked seeds. Cycloheximide (10(-6) M) inhibits the appearance of phytase by 61% during 24 and 48 hours after the start of germination. This phytase increase is dependent on the synthesis of new RNA in the cotyledon. Synthesis of DNA is not detected in the cotyledon during germination.
摘要
在发芽的绿豆种子中，植酸的降解与子叶中植酸酶活性的增加有关。在分化的胚中，在研究的整个生长期间，这种活性的增加非常低。植酸酶在发芽过程中出现在子叶中。在未浸泡的种子的子叶中未检测到活性。在发芽开始后 24 和 48 小时，环已亚胺（10（-6）M）抑制植酸酶的出现达 61%。这种植酸酶的增加依赖于子叶中新 RNA 的合成。在发芽过程中，子叶中未检测到 DNA 的合成。
