Background
- Kenaf (Hibiscus cannabinus) is a fiber crop known for heavy metal tolerance.
- Natural resistance-associated macrophage (Nramp) proteins are crucial for metal ion transport and stress response in plants.
Purpose Of The Study
- To identify and characterize the Nramp gene family in kenaf at the whole genome level.
- To understand the potential role of kenaf Nramp genes in cadmium (Cd) stress response.
Main Methods
- Whole genome analysis of kenaf.
- Phylogenetic analysis of HcNramp proteins.
- Analysis of gene structure, motifs, and promoter elements.
- Gene expression analysis in different tissues under various treatments.
Main Results
- Fifteen HcNramp genes were identified in kenaf, unevenly distributed on chromosomes.
- Phylogenetic analysis revealed 3 subfamilies, with conserved motifs and gene structures within subfamilies.
- Promoter regions showed enrichment for hormone response, meristem expression, and environmental stress elements.
- HcNramp gene expression varied by tissue, with predominant root expression, suggesting a role in heavy metal uptake.
Conclusions
- The Nramp gene family in kenaf has unique characteristics and potential roles in heavy metal tolerance.
- Findings provide a foundation for screening kenaf genes involved in cadmium tolerance and phytoremediation.
