        abstract = {NAC has been considered one of the largest transcription factor families in plant species. In 
peanut (Arachis hypogaea), 29 members of the AhNAC gene family have been identified and 
characterized. However, the information of their functions related to the mechanism of the stress 
response has been reported. In this study, a total of seven duplication events, which occurred 
from the segmental duplication, has been predicted in the AhNAC gene family in peanuts. The 
Ka/Ks ratios revealed that natural selection prevented the presence of the point mutations in the 
most duplicated genes, consequently, maintaining their structure and function during evolution. 
Based on the unrooted phylogenetic tree between AhNAC proteins in peanuts and 23 drought?responsive CaNAC in chickpea (Cicer arietinum), we proposed 12 members of the AhNAC that 
potentially share similar functions with well-characterized NAC in chickpea. Furthermore, 
various hormone- and drought-responsive cis-regulatory elements have been found in the 
promoter regions of these candidate genes. Re-analysis of the previous RNA-Seq demonstrated 
that the majority of the candidate AhNAC genes were responsive to the osmotic stress. Taken 
together, our study could provide an important foundation for further functional characterization 
towards the improvement of stress tolerance in peanuts.}
