Abstract:

In order to excavate the key genes in wheat which were resistant to glufosinate-ammonium stress and analyze family members chromosome distribution and expression pattern.Winter wheat Jinnong 6 was selected as the research object and different concentrations of glufosinate-ammonium was used in our study and observed symptoms of wheat after treatments.Total RNA was extracted from wheat leaves at 0,3 and 9 h after treatment.Transcriptomic sequencing technology was used to analyze and excavate the key genes in wheat.To confirm genes expression,protein structure of their family members and expression pattern.The results showed that TraesCS4A02G044000 was up-regulated induced by glufosinate-ammonium stress according to transcriptome analysis.Sequence analysis showed that TraesCS4A02G044000 was located in the 4th homologous gene A genome of wheat.The protein domain analysis showed that the protein encoded of TraesCS4A02G044000 had a signal peptide,a DUF568 and a b561.Twelve genes containing DUF568 and b561 domains were excavated from the genome family members,which were located in the 4th,5th and 7th homologous groups.The expression pattern analysis showed that TraesCS4D02G265000,TraesCS4B02G265100 and TraesCS4A02G044000 located in chromosomes A,B and D of the 4th homologous group which encoded cytochrome b561 were up-regulated obviously in wheat under glufosinate-ammonium stress. TraesCS4A02G044000 and its homologous genes encoding cytochrome b561 were significantly up-regulated under glufosinate-ammonium stress, indicated that b561 had a positive response to glufosinate-ammonium stress and participated in the metabolism of glufosinate-ammonium in wheat.

Key words: Wheat, Glufosinate-ammonium stress, Transcriptome analysis, Gene localization and expression pattern
