Genome-wide Identification and Expression Analysis of SBP Genes in Panicum miliaceum
摘要
Abstract
Squamosa promoter binding protein(SBP)gene family is widely involved in plant growth and development,signal transduction,and many physiological and biochemical processes.Here,we identified a total of 25 SBP genes in the proso millet(Panicum miliaceum)genome,which were divided into 6 subfamilies through phylogenetic analysis.The members of the same subfamily had similar gene structure and conserved motifs.The collinearity analysis revealed 7 pairs of orthologous genes with Arabidopsis thaliana AtSBP and 31 pairs with Oryza sativa OsSBP.The analysis of cis-acting elements showed that the promoter region of SBP genes in P.miliaceum was rich in elements related to stress,plant light response and plant hormone signal response.The analysis of gene expression patterns showed that the SBP genes in P.miliaceum had obvious tissue specificity,variety specificity,and developmental stage specificity,suggesting important roles of SBP genes in the growth and development of P.miliaceum.The results provide a basis for further studying the biological function of SBP gene family in the growth and development of P.miliaceum and a reference for studying the SBP genes in other crops.关键词
