中文摘要	oligochitosan has a variety of biological activities. the presence of oligochitosan triggers a wide range of cellular responses including changes in gene expression and synthesis of pr proteins. to investigate the ability of oligochitosan to affect gene transcription, the messenger rna (mrna) differential display technique was applied to the identification and isolation of genes whose transcription was altered in cultured nicotiana tabacum (var. samsun nn) plants that were treated with oligochitosan. one gene whose mrna levels significantly changed in response to oligochitosan was isolated and identified. reverse northern blot and rt-pcr analysis indicated that the expression of the gene was up-regulated by oligochitosan. sequence and homology analysis show that the fragment share 62% identity with polyubiquitin of maize. because the ubiquitin protein is relevant to plant defense response and hypersensitive response, so these results suggested that oligochitosan can induce plant resistance and its mechanism may be relevant to ubiquitination. these findings also demonstrate the usefulness of mrna differential display technique for the detection of plant metabolic pathways affected by oligochitosan.
