Societal Impact Statement Iron deficiency anaemia remains a major public health challenge in Sub-Saharan Africa. We compiled a list of indigenous African underutilized wild food plants and examined their potential for addressing micronutrient deficiencies.

🕰️🌸 RESEARCH 🌸🕰️ Ngigi et al. explore reproductive stage-dependent responses of rosette leaves to iron availability, revealing distinct growth, elemental contents, and gene expression patterns between old and young leaves and stages 🌿 🔗 doi.org/10.1093/jxb/... #PlantScience 🧪
Fig. 2 (shortened, full legend in paper): Leaf-by-leaf analysis of Arabidopsis thaliana at the rosette stage (RS). (A) At the RS, plants were transferred to respective Fe-sufficient (+Fe) or -deficient (−Fe) Hoagland media solutions and growth was recorded from day 0 till day 7. (B) Leaf images of leaf 1 (L1) to 10 (L10) under the two Fe conditions, as indicated. (C) Cumulative rosette convex hull area as recorded from (A). Data represent means of biological replicates (n = 3). Error bars represent ± SD. Statistical analysis was done using one-way ANOVA and Tukey’s HSD test. Means followed by the same letter are not significantly different (P < 0.05). (D) Radial charts showing the leaf areas of leaf 3 and 8 after exposure to either +Fe (control) or −Fe conditions from day 1 to day 7. Radial charts were plotted in R Studio using the ‘fmsb’ package. Plants were grown for 3 weeks before culturing in either +Fe or −Fe conditions.
