Abstract

Plant-specific lateral organ boundaries domain (LBD) proteins play important roles in plant growth and development. Foxtail millet () is one new C model crop. However, the functions of foxtail millet genes are unknown. In this study, a genome-wide identification of foxtail millet genes and a systematical analysis were conducted. A total of 33 genes were identified. They are unevenly distributed on nine chromosomes. Among these genes, six segmental duplication pairs were detected. The thirty-three encoded SiLBD proteins could be classified into two classes and seven clades. Members in the same clade have similar gene structure and motif composition. Forty-seven kinds of -elements were found in the putative promoters, and they are related to development/growth, hormone, and abiotic stress response, respectively. Meanwhile, the expression pattern was investigated. Most genes are expressed in different tissues, while several genes are mainly expressed in one or two kinds of tissues. In addition, most genes respond to different abiotic stresses. Furthermore, the function of , which is mainly expressed in roots, was characterized by ectopic expression in and rice. Compared to controls, transgenic plants generated shorter primary roots and more lateral roots, indicating the function of in root development. Overall, our study laid the foundation for further functional elucidation of genes.
