The researchers studied a gene called DwMYB2 in Arabidopsis plants to understand how it affects iron transport from roots to shoots. They found that plants with DwMYB2 had higher iron levels in their roots compared to wild-type plants, leading to imbalanced iron levels between roots and shoots. This imbalance suggests that DwMYB2 affects the translocation of iron from roots to shoots. The gene expression analysis showed that genes involved in iron transport were downregulated in plants with DwMYB2. Additionally, the expression of genes related to peptide transport was altered in the transgenic plants. These findings provide insights into how DwMYB2 influences iron balance in plants and identify potential candidate genes for further study.
