Abstract

The transcription factor family members play crucial roles in controlling plant growth and development, as well as responses to various abiotic stresses. Genome-wide identification and characterization of genes has not yet been carried out in the oil palm genome. In the present work, we reported the occurrence of 172 (AP2, ERF, & members) through genome-wide identification. Phylogenetic analysis was used to divide them into four groups, including: 34 AP2, 131 ERF, 5 , and 2 gene family members. All 172 members were unevenly distributed across 16 chromosomes of oil palm. Gene duplication analysis elucidated the tandem duplication of s on chromosome blocks of the oil palm genome during evolution. Gene structure as well as conserved motif analysis demonstrated the conserved nature of intron/exon organization and motifs among the genes. Several cis-regulatory elements-related to hormone, stress, and defense responses-were identified in the promoter regions of s. Tissue-specific expression of 172 s in five different tissues of oil palm was also revealed by heatmap analysis using the available transcriptome data. Finally, abiotic stress (salinity, cold & drought)-responsive s in the oil palm genome were validated through qPCR analysis. Our study provided valuable information on oil palm superfamily members and dissected their role in abiotic stress conditions.
