摘要：

Ubiquitin is an omnipresent protein found in all eukaryotes so far analysed. It is involved in several important processes, including protein turnover, chromosome structure and stress response. Parsley (Petroselinum crispum) contains at least two active polyubiquitin (ubi4) genes encoding hexameric precursor proteins. The deduced amino acid sequences of the ubiquitin monomers are identical to one another and to ubiquitin sequences from several other plant species. Analysis of the promoter region of one ubi4 gene revealed putative regulatory elements. In parsley plants, the ubi4 mRNAs were the predominant ubiquitin mRNAs and were present at comparable levels in all plant organs tested. In cultured parsley cells, high levels of ubiquitin gene expression remained unaffected by heat shock, elicitor or light treatment.
