Identification and Bioinformatics Analysis of P14K Gene Family in Maize
Phosphatidylinositol 4-kinase(PI4K),a key enzyme in the metabolism of phosphatidylinositol signal-ing pathway,plays an important role in the growth of plants.Thirteen ZmPI4K family members were identified from maize databases by bioinformatics,and the members of ZmPI4Ks were analyzed by phylogenetic,motif,gene struc-ture,tissue expression patterns,cis-acting elements,induced expression,and reciprocal proteins.The results showed that the maize ZmPI4K family was divided into three subfamilies:γ,β,and α.The motifs and gene struc-tures of the members belonging to the same subfamily were similar.ZmPI4Ks members were expressed in different tissues.The results of cis-acting elements and induced expression suggest that ZmPI4Ks may be involved in plant growth and development in response to environmental or hormonal stress;the results of interacting protein predic-tion imply that ZmPI4Ks members may respond to abiotic stress by interacting with proteins involved in lipid synthe-sis and transporting.This study aims to provide a theoretical basis for exploring the PI4K family of maize and other species,and provide genetic resources for molecular breeding.
