【Objective】 The aim of this study was to explore the characteristics of peanut ASR gene family and their roles in drought and salt stress responses, and to provide potential gene loci for the breeding of drought and salt-resistant peanut varieties. 【Methods】 The ASR gene family of peanut was identified at the genome level and analyzed in basic characteristics by bioinformatics methods, and the expression changes of ASR gene family under 200 mmol/L NaCl and PEG treatment were analyzed by using transcriptome data. 【Results】 (1) Seven peanut ASR genes were identified by analyzing the reference genome of peanut cultivar Shitouqi, and the theoretical isoelectric point (pI) was between 5.34-6.98. the Aliphatic index was between 23.77-56.84, and the GRAVY value was negative, indicating that these seven proteins were hydrophilic proteins. (2) The expression pattern of AhASR3 and AhASR7 genes was similar, with high transcription level, similar gene structure, protein structure domain and the number of conserved motifs, and motif 5, 6, and 9 were only found in AhASR3 and AhASR7 proteins. (3) The promoter regions of AhASR1, AhASR5 and AhASR2 had drought-induced MYB transcription factor binding sites, and the promoter regions of AhASR1, AhASR2 and AhASR4 had ABA response elements. (4) The result of transcriptome analysis of peanut salt stress treatment showed that AhASR2, AhASR3 and AhASR7 were upregulated in the root after 200 mmol/L NaCl treatment. (5) The result of transcriptome analysis of PEG treatment showed that the transcription levels of AhASR1, AhASR3, AhASR4 and AhASR7 were up-regulated more than twice after PEG treatment for 4 h or 8 h. 【Conclusion】 The basic characteristics of peanut ASR family genes and proteins were preliminarily clarified, and the ASR genes that may be involved in salt and drought stress responses were identified, which provided potential target genes for further breeding salt- and drought-tolerant peanut varieties.
