摘要：

A cDNA clone (ScRPS7) encoding the cytoplasmic ribosomal protein S7 was isolated from a rye leaf cDNA library and sequenced. The deduced protein of 192 amino acids with M-r 22 189 shows identity of 52% or 47%, respectively, relative to S7 proteins of human or yeast. A RPS7 mRNA accumulation is higher in the meristematic zone at the leaf base than in the non-meristematic middle and upper section of leaves. Short periods of cold stress sharply reduce the mRNA level while leaves of cold hardened plants contain normal levels of ScRPS7 transcripts. (C) 2000 Elsevier Science B.V. All rights reserved.
