Abstract:

To investigate the potential functions of DUF760s in rice growth and development,the genome-wide identification,classification,promoter sequence and expression profile analysis of the DUF760 gene family were performed.This research identified 6 and 8 members of DUF760 gene family in rice and Arabidopsis respectively by bioinformatics analysis.Phylogenetic tree analysis divided these members into two subfamilies,there were also some characteristic differences between the two subfamilies in protein conserved motif and gene structure.Multiple cis-acting elements responding to stresses and phytohormones existed in the promoter regions of rice DUF760 family genes.ABRE(abscisic acid response)element was present in the promoter sequence of all DUF760 family members,the promoter region of OsDUF760-1 possessed 9 abscisic acid(ABA)related response elements.The transcriptional expression level of OsDUF760-1 in rice was significantly down-regulated after ABA treatment,while OsDUF760-3 was significantly up-regulated.The expression change patterns of these two genes in rice after drought stress treatment were consistent with that after ABA treatment,which indicated that these two genes may participate in rice drought stress response through ABA signaling pathway,and play different roles.In addition to strong responses to ABA and drought stress treatments,members of rice DUF760 family also showed relatively strong expression changes in response to JA(Jasmonic acid),low temperature and M.oryzae treatments.
