Abstract

Chlamydomonas reinhardtii cells treated with toluene at 0 degrees C and 25 degrees C incorporate ribonucleoside triphosphates (NTPs) into chloroplast RNA at 25 degrees C and also at 35 degrees C. The incorporation requires all four NTPs and Mg2+, and is completely inhibited by DNase, RNase, actinomycin D (40 microgram/ml) and rifampicin (350 microgram/ml). However, the incorporation is almost totally insensitive to both alpha-amanitin and streptolydigin at 200 microgram/ml.

摘要

在0摄氏度和25摄氏度下用甲苯处理的莱茵衣藻细胞,在25摄氏度以及35摄氏度时会将核糖核苷三磷酸(NTPs)掺入叶绿体RNA中。这种掺入需要所有四种NTPs和Mg2+,并且会被DNase、RNase、放线菌素D(40微克/毫升)和利福平(350微克/毫升)完全抑制。然而,在200微克/毫升时,这种掺入对α-鹅膏蕈碱和利链菌素几乎完全不敏感。
