| description | Lateral organ boundaries domain (LBD) proteins are plant-specific transcription factors that play important roles in organ development and stress response. However, the function of <i>LBD</i> genes has not been reported in Euphorbiaceae. In this paper, we used <i>Jatropha curcas</i> as the main study object and added rubber tree (<i>Hevea brasiliensis</i>), cassava (<i>Manihot esculenta</i> Crantz) and castor (<i>Ricinus communis</i> L.) to take a phylogenetic analysis of <i>LBD</i> genes. Of LBD, 33, 58, 54 and 30 members were identified in <i>J. curcas</i>, rubber tree, cassava and castor, respectively. The phylogenetic analysis showed that <i>LBD</i> members of Euphorbiaceae could be classified into two major classes and seven subclasses (Ia-Ie,IIa-IIb), and <i>LBD</i> genes of Euphorbiaceae tended to cluster in the same branch. Further analysis showed that the <i>LBD</i> genes of Euphorbiaceae in the same clade usually had similar protein motifs and gene structures, and tissue expression patterns showed that they also have similar expression profiles. <i>JcLBD</i>s in class Ia and Ie are mainly expressed in male and female flowers, and there are multiple duplication genes with similar expression profiles in these clades. It was speculated that they are likely to play important regulatory roles in flower development. Our study provided a solid foundation for further investigation of the role of <i>LBD</i> genes in the sexual differentiaion of <i>J. curcas</i>. |
