Phenylalanine Ammonia-Lyase (PAL) Genes Family in Wheat (Triticum aestivum L.): Genome-Wide Characterization and Expression Profiling

Phenylalanine ammonia-lyase (PAL) is the first enzyme in phenylpropanoid pathway and plays a vital role adoption, growth, development plants but wheat its characterization still not very clear. Here, we report genome-wide identification of TaPAL genes analysis their transcriptional expression, duplication, phylogeny wheat. A total 37 that cluster into three subfamilies have been identified based on phylogenetic analysis. These are distributed 1A, 1B, 1D, 2A, 2B, 2D, 4A, 5B, 6A, 6B, 6D chromosomes. Gene structure, conserved domain analysis, investigation cis-regulatory elements were systematically carried out. Chromosomal rearrangements gene loss observed by evolutionary orthologs among Triticum urartu, Aegilops tauschii, aestivum during origin bread ontology revealed PAL play plant growth. We also 27 putative miRNAs targeting genes. The high expression level was detected roots drought-tolerant genotypes compared to drought-sensitive genotypes. However, low expressions TaPAL10, TaPAL30, TaPAL32, TaPAL3, TaPAL28 recorded all Arogenate dehydratase interacts with TaPAL29 has higher roots. RNA-seq data showed they expressed shoots under normal abiotic stress. Our study offers valuable functioning
