Abstract：NAC gene family encode a kind of plant specific important transcriptional factors,which are involved extensively in plant growth,development and organogenesis and stress responses. However,up to date,little is known about NAC genes in Bothriochloa ischaemum. Hence,by utilizing the bioinformatics method,we analyzed the physical and chemical characteristics of encoding proteins,conserved motif,subcellular localization,potential phosphorylation sites and evolutionary relationship of 21 NAC family protein sequence from B. ischaemum. The result showed that these 21 amino acid sequences could be clustered into ten groups. The secondary structure of NAC genes was mainly random coil,containing 5 conserved motifs. Most of the NAC proteins were located in the nucleus,and potential phosphorylation sites analysis indicated that all NAC proteins contain Ser,Thr and Tyr phosphorylation sites.These results of this investigation could definitely provide a significant foundation for further research on the functional analysis of Bothriochloa ischaemum NAC gene family.
