| Summary: | Panicle development and grain production in crop species are essential breeding characteristics affected by the synthesis of auxin, which is influenced by flavin monooxygenase-encoding genes such as <i>YUC</i> (<i>YUCCA</i>) family members. In this trial, fourteen <i>YUCs</i> were identified and named uniformly in foxtail millet, an ancient crop species cultivated across the world. The phylogenetic analysis revealed that the <i>SiYUCs</i> were clustered into four subgroups; protein motif and gene structure analyses suggested that the closely clustered <i>SiYUC</i> genes were relatively conserved within each subgroup; while genome mapping analysis indicated that the <i>SiYUC</i> genes were unevenly distributed on foxtail millet chromosomes and colinear with other grass species. Transcription analysis revealed that the <i>SiYUC</i> genes differed greatly in expression pattern in different tissues and contained hormonal/light/stress-responding <i>cis</i>-elements. The haplotype characterization of <i>SiYUC</i> genes indicated many superior haplotypes of <i>SiYUCs</i> correlated with higher panicle and grain weight could be favorably selected by breeding. These results will be useful for the further study of the functional characteristics of <i>SiYUC</i> genes, particularly with regard to the marker-assisted pyramiding of beneficial haplotypes in foxtail millet breeding programs. |
