Abstract:

In order to understand the function of DUF966 family genes(ZoDUF966)in ginger,the biological information method was used to systematically identify them. A total of 11 ZoDUF966 were identified and classified into groups a,b and c,including 5,4 and 2 members,respectively. All ZoDUF966 proteins were hydrophilic proteins and localized in the nucleus. Except for ZoDUF966_1b,ZoDUF966_3b and ZoDUF966_11a,the other 8 proteins were alkaline proteins. In the secondary structure of the protein,α-helix and random coil are dominant,and there are some differences in the tertiary structure. Eleven ZoDUF966 were distributed on six chromosomes,except for four and three genes on chromosomes 6 and 16,respectively,and only one gene on each of the other four chromosomes. The promoter sequence of ZoDUF966 contains cis-acting elements related to light response,stress,growth and development,and plant hormones. Gene expression analysis based on transcriptome sequencing data showed that the expression of ZoDUF966 was different in different growth periods,different tissues,biotic and abiotic stresses. Among them,ZoDUF966_6c responded to low temperature stress,and ZoDUF966_9b was highly up-regulated after inoculation with Fusarium solani. qRT-PCR results showed that ZoDUF966 responded to drought,flooding and salt stresses. Under drought stress,ZoDUF966_6c/10a/11a in roots and ZoDUF966_7a/11a in rhizomes were significantly up-regulated,while ZoDUF966_1b/4b and ZoDUF966_8a/1a in rhizomes were significantly down-regulated. Under salt stress,ZoDUF966_9b and ZoDUF966_7a were significantly up-regulated in roots,and ZoDUF966_5a was significantly down-regulated in roots. Under waterlogging stress,ZoDUF966_7a and ZoDUF966_10a were significantly up-regulated in rhizome,while ZoDUF966_1b in leaves and ZoDUF966_11a in roots were significantly down-regulated.
