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.

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.

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 🌿

Everywhere female humans live longer than males, is also the case for many other mammals, despite of the dangers in female lives - there is an evolutionary benefit to this! So many men in the world are stupid and so all other men will never be able to understand the inborn body weaknesses.

Der Schmalblättrige Doppelsame wächst gerne in Pflasterritzen, aber auch in zahlreichen anderen Habitaten. Fotos: Bruno Walther

Pflanzen wachsen durch Pflasterstein, an Steinmauern entlang und wuchern an den scheinbar ungewöhnlichsten Stellen - sie trotzen vielen Widrigkeiten und passen sich an. Wie machen sie das? Und was bedeutet der Klimawandel für unsere heimischen Pflanzen? Welche Anpassungsstrategien haben sie? 1/3

Age-dependent differential iron deficiency responses of rosette leaves during reproductive stages in Arabidopsis thaliana Iron (Fe) is essential for plant development throughout the life cycle. Rosette leaves are responsive to Fe supply in Arabidopsis thaliana. Little is known about the dynamics of Fe deficiency (-Fe) re...

At various reproductive stages, young rosette leaves are supersensitive to iron deficiency - growth is inhibited very rapidly and gene expression and metal contents change, see Mary's revised preprint at www.biorxiv.org/content/10.1...

Iron homeostasis in the annual and perennial stem zones of Arabis alpina Iron accumulates in secondary growth tissues in the perennial stem zone and is correlated with particular gene expression patterns in the perennial model plant Arabis alpina.

@botanyhhu.bsky.social 's team found:

Secondary growth in proximal perennial stem zone plays a role in iron storage in perennial Arabis alpina, while distal annual stem zones may transiently store iron for seed production.
