| Abstract | Iron (Fe) and Zinc (Zn) are essential micronutrients for plant growth and development. ZIP (ZRT, IRT-like protein) transporters, known for their role in the regulation of Zinc and Iron uptake, are pivotal in facilitating the absorption, transport, and maintenance of Fe/Zn homeostasis in plants. Nicotiana tabacum has been widely used as a model plant for gene function analysis; however, the tobacco ZIP genes have not been identified systematically. In this study, we have identified a comprehensive set of 32 NtZIP genes, which were phylogenetically categorized into three distinct clades. The gene structures, characterized by their exon/intron organization, and the protein motifs are relatively conserved, particularly among genes within the same clade. These NtZIP genes exhibit an uneven distribution across 12 chromosomes. The gene localization analysis revealed the presence of 11 pairs of homeologous locus genes and 7 pairs of tandem duplication genes within the genome. To further explore the functionality of these genes, real-time quantitative reverse transcription PCR was employed to assess their expression levels in roots subjected to metal deficiency. The results indicated that certain NtZIP genes are specifically upregulated in response to either Fe or Zn deficiency. Additionally, the presence of specific cis-elements within their promoter regions, such as the E-box associated with Fe deficiency response and the ZDRE box linked to Zn deficiency response, was identified. This study lays a foundational groundwork for future research into the biological functions of NtZIP genes in tobacco in micronutrient regulation and homeostasis. |
