Genome-Wide Analysis of the Lateral Organ Boundaries Domain (LBD) Gene Family in Sweet Potato (<i>Ipomoea batatas</i>)
The <i>LBD</i> family is a plant-specific transcription factor family that plays an important role in a variety of biological processes. However, the function of <i>IbLBD</i> genes in sweet potato remains unclear. In this study, we identified a total of 53 <i>IbLBD</...

| description | The <i>LBD</i> family is a plant-specific transcription factor family that plays an important role in a variety of biological processes. However, the function of <i>IbLBD</i> genes in sweet potato remains unclear. In this study, we identified a total of 53 <i>IbLBD</i> genes in sweet potato. Genetic structure showed that most of the <i>IbLBD</i> genes contained only two exons. Following the phylogenetic investigation, the <i>IbLBD</i> gene family was separated into Class I (45 members) and Class II (8) members. Both classes of proteins contained relatively conservative Motif1 and Motif2 domains. The chromosomal locations, gene duplications, promoters, PPI network, and GO annotation of the sweet potato <i>LBD</i> genes were also investigated. Furthermore, gene expression profiling and real-time quantitative PCR analysis showed that the expression of 12 <i>IbLBD</i> genes altered in six separate tissues and under various abiotic stresses. The <i>IbLBD</i> genes belonging to Class I were mostly expressed in the primary root, the pencil root, and the leaves of sweet potatoes, while the genes belonging to Class II were primarily expressed in the various sweet potato roots. The <i>IbLBD</i> genes belonging to Class I were mostly expressed in the primary root, the pencil root, and the leaves of sweet potatoes, while the genes belonging to Class II were primarily expressed in the fibrous root, pencil root, and tuber root. |
