Abstract：Clp is a kind of ATP -dependent protease widespreading in prokaryote and eukaryote,which plays an important role in resisting biotic and abiotic stresses in plants.To improve the understanding of Clp genes in peanut,28 Clp genes were screened by one transcriptome library constructed with peanut leaves. These 28 Clp genes distributed on 9 chromosomes respectively of A genome of wild peanut.Clustering analysis showed that these 28 Clp genes were assorted to ClpB,C,D,X,P,R,S groups reported previously.To ana-lyze the response to salinity stress of 28 Clp genes,digital gene expression profiles were constructed using a mutant with higher salinity resistance (S2)and its control (S4)before and after treated with 250 mmol /L NaCl.The results showed that 16 Clp genes were responsive to salinity stress in S2 and /or S4.This study pro-vided bases for functional researches and application of Clp genes in peanut.
