Genome-wide identification and characterization of HD-ZIP genes in potato.

Abstract

HD-ZIP (Homeodomain leucine zipper) transcription factors play an important regulatory role in stress resistance in plants. The purpose of this study was to analyze the characteristics of the HD-ZIP genes/proteins and to study their expression profiles under high and low temperature conditions in potato (Solanum tuberosum L.). A strict homology search was used to find 43 HD-ZIP genes located on potato chromosomes 1-12. Exons/introns, protein features and conserved motifs were analyzed, and six segment duplications were identified from 43 HD-ZIP genes. Then, we analyzed the data from the PGSC (Potato Genome Sequencing Consortium) database regarding the expression of 43 HD-ZIP genes that were induced by biotic and abiotic stresses and phytohormone treatments and conducted an expression analysis for these genes across all potato life stages. Additionally, the expression levels of 13 HD-ZIP genes were analyzed under high temperature (37 °C) and low temperature (4 °C) conditions. The results showed that the transcript levels of all 13 genes changed, which indicated that these genes respond to heat and cold in plants. Especially for StHOX20, the expression significantly upregulated in roots at 37 °C and 4 °C. Our findings laid the foundation and provided clues for understanding the biological functions of HD-ZIP family genes.
