Plant Secondary Metabolites as Defenses, Regulators, and Primary Metabolites: The Blurred
Functional Trichotomy | Plant Physiology | Oxford Academic Skip to Main Content Advertisement …

Plant growth performance under a stressful environment, notably in the agriculture field, is
directly correlated with the rapid growth of the human population, which triggers the …

Micronutrients like copper (Cu), manganese (Mn), Iron (Fe), and Zinc (Zn) are essential for
plants, and their functions are tightly linked for vital metabolism. The normal concentration …

Iron is an essential but poorly bioavailable nutrient because of its low solubility, especially in
alkaline soils. Here, we describe the discovery of a previously undescribed redox-active …

Soil communities are diverse taxonomically and functionally. This ecosystem experiences
highly complex networks of interactions, but may also present functionally independent …

Plants are the principal source of dietary iron (Fe) for most of Earth's population and Fe
deficiency can lead to major health problems. Developing strategies to improve plant Fe …

Highlights•Strategy I plants secrete riboflavins or phenolics to facilitate Fe
acquisition.•Strategy II plants secrete phytosiderophores to acquire Fe.•Exudation of organic …

Although iron (Fe) is one of the most abundant elements in the earth's crust, its low solubility
in soils restricts Fe uptake by plants. Most plant species acquire Fe by acidifying the …

Secondary metabolites are important facilitators of plant–microbe interactions in the
rhizosphere, contributing to communication, competition, and nutrient acquisition. However …

Summary Studies of Iron (Fe) uptake mechanisms by plant roots have focussed on Fe (III)‐
siderophores or Fe (II) transport systems. Iron deficency also enhances root secretion of …
