Genome-wide and transcriptome analysis of PdWRKY transcription factors in date palm (Phoenix dactylifera) revealing insights into heat and drought stress tolerance.

ABSTRACT: Genomic and transcriptomic studies on date palm (Phoenix dactylifera) are still inadequate, but several studies have contributed to understanding its genetic makeup, especially in the Khalas cultivar. Looking at the extensive importance of WRKY transcription factors (TFs) in plant growth, development and defense responses to various biotic and abiotic stresses, we conducted a study to identify and functionally annotate the WRKY TFs of P. dactylifera, with a particular focus on their involvement in drought and heat stress. A total of 73 PdWRKY TFs were curated and classified into 7 and 17 clades through comparative phylogenetic analysis and orthologous comparison of the WRKY TFs from the extensively studied genomes of Arabidopsis thaliana and Oryza sativa, respectively. Our findings show th
