萌发小麦胚中的RNA聚合酶I和II。

Acta Biochim Pol. 1976;23(2-3):261-7.

The RNA polymerase I was practically absent in the resting embryos and appeared several hours after the beginning of imbibition, whereas the level of polymerase II was high in the resting embryos and did not increase significantly during the imbibition phase. 2. Incorporation in vivo of [14C]valine into polymerase I and II indicated that the synthesis of RNA polymerase I is initiated in germinating embryos much earlier than that of RNA polymerase II. 3. It is suggested that RNA polymerase II is stored in resting wheat embryos to support mRNA synthesis at the onset of germination, whereas the RNA polymerase I activity appears at a further stage of germination.

静止胚胎中几乎不存在RNA聚合酶I，在吸水开始数小时后出现，而聚合酶II在静止胚胎中的水平较高，在吸水阶段没有显著增加。2. 体内将[14C]缬氨酸掺入聚合酶I和II表明，RNA聚合酶I的合成在萌发胚胎中比RNA聚合酶II早得多开始。3. 有人认为，RNA聚合酶II储存在静止的小麦胚胎中，以支持萌发开始时的mRNA合成，而RNA聚合酶I的活性在萌发的进一步阶段出现。
