摘　　要：Through construction of a subtracted cDNA library and library screening, a number of salt-induced cDNA fragments have been cloned from Populus euphratica. Based on the results of DNA sequencing and Northern analysis, the gene response of Populus euphratica to salt stress is discussed. It is indicated that in response to salt treatment the transcription level for some genes of Populus euphratica increases by about 1.5 times and significant difference between the responses to osmotic stress and to ion stress has been observed in gene activity.Through construction of a subtracted cDNA library and library screening, a number of salt-induced cDNA fragments have been cloned from Populus euphratica.
