Following treatment with ABA an inhibition of total RNA synthesis was observed after 30 hours. Total soluble ribonuclease activity did not change during the first 8 hours, after which an increase could be observed.Separation of nucleic acids with polyacrylamide gel electrophoresis indicated that synthesis of soluble RNA was less inhibited by ABA than synthesis of ribosomal RNA.Effects of 5-FU and ABA on ribosomal RNA precursor were investigated. It could be shown that 5-FU did not inhibit ribosomal precursor synthesis, but that ABA did so.
用 ABA 处理后，在 30 小时后观察到总 RNA 合成受到抑制。在最初的 8 小时内，总可溶性核糖核酸酶活性没有变化，之后可以观察到增加。用聚丙烯酰胺凝胶电泳分离核酸表明，ABA 对可溶性 RNA 的合成抑制作用小于对核糖体 RNA 的合成抑制作用。研究了 5-FU 和 ABA 对核糖体 RNA 前体的影响。结果表明，5-FU 不抑制核糖体前体合成，但 ABA 抑制其合成。
