Genome-Wide Analysis of <i<SPL</i</miR156 Module and Its Expression Analysis in Vegetative and Reproductive Organs of Oil Palm (<i<Elaeis guineensis</i<)
The <i<SPL</i< (SQUAMOSA-promoter binding protein-like) gene family is one of the largest plant transcription factors and is known to be involved in the regulation of plant growth, development, and stress responses. The genome-wide analysis of <i<SPL</i< gene members in a diverse range of crops has been elucidated. However, none of the genome-wide studies on the <i<SPL</i< gene family have been carried out for oil palm, an important oil-yielding plant. In this research, a total of 24 <i<EgSPL</i< genes were identified via a genome-wide approach. Phylogenetic analysis revealed that most of the <i<EgSPL</i<s are closely related to the Arabidopsis and rice <i<SPL</i< gene members. <i<EgSPL</i< genes were mapped onto the only nine chromosomes of the oil palm genome. Motif analysis revealed conservation of the SBP domain and the occurrence of 1–10 motifs in <i<EgSPL</i< gene members. Gene duplication analysis demonstrated the tandem duplication of <i<SPL</i< members in the oil palm genome. Heatmap analysis indicated the significant expression of <i<SPL</i< genes in shoot and flower organs of oil palm plants. Among the identified <i<EgSPL</i< genes, a total 14 <i<EgSPL</i<s were shown to be targets of miR156. Real-time PCR analysis of 14 <i<SPL</i< genes showed that most of the <i<EgSPL</i< genes were more highly expressed in female and male inflorescences of oil palm plants than in vegetative tissues. Altogether, the present study revealed the significant role of <i<EgSPL</i< genes in inflorescence development..
