摘要：

Genomic clones of 2.8 kb, 3.3 kb and 6.5 kb for the S-2-, S-3- and S-5-RNases of Japanese pear (Pyrus pyrifolia), respectively, were isolated and sequenced. Comparison of the 5'-flanking regions of these genes with the same region of the S-4-RNase gene indicated that a highly similar region of approximately 200 bp exists in the regions just upstream of the putative TATA boxes of the four Japanese pear S-RNase genes. This suggests the presence of cis-regulatory element(s) in this region.
