Elimination of Hidden Hunger by Micronutrients Remobilization

Elimination of Hidden Hunger by Micronutrients Remobilization

The Elimination of Hidden Hunger world is increasingly facing the challenge of hidden hunger. A form of malnutrition occurs when people don’t have enough essential vitamins and minerals in their diets. This can lead to health problems such as disease, stunted growth, and even death. A recent study has shown that plants can help to address this issue. The study, published in Nature Plants, made use of a model plant to understand how plants mobilize nutrients from the soil to increase their nutritional content.

Elimination of Hidden Hunger is affecting a significant portion of the population all over the globe and this problem must be eliminated to reduce disease burden and health disorders. Remobilization of some nutrients from vegetative tissues occurs during the senescence of developmental stages. Typically mass senescence occurs at the end of growing seasons. Most likely the remobilized nutrients move to develop seeds in the annual crop species.

Stages of Remobilization

When a person comes into custody, they are going to be detained on remand. ” There are three stages that a person on remand may experience: arrest, first court appearance, and second court appearance. At each of these stages, the onus is upon the Crown Prosecutor to be ready to proceed with the trial.

Estimation of Remobilization in Plants

Nutrient mobilization can be estimated by the apparent remobilization method that simply relies on the number of total nutrients. That is present in different organs of plants at different times and developmental stages. Mostly immobilization occurs by the phloem pathways and all macronutrients other than Calcium can easily move through the phloem. While, micronutrients show moderate mobility in the phloem but there is an exception for manganese. Like This: How to Make High Quality Phosphorus Fertilizer DIY

“This study opens up the exciting possibility that increased micronutrient uptake by plants could help to alleviate hidden hunger in a cost-effective way, with potential benefits for human health and agricultural productivity,” said lead study author Amaury Dehez, a postdoctoral fellow at the University of Paris-Saclay.

Eliminating hidden hunger is a challenge because it does not always manifest itself in ways that we can see, such as stunted growth or diarrhea. However, it can lead to certain deficiencies and health problems that may not be immediately apparent on the surface.

Seasonal Patterns Related to Micronutrient Remobilization

Different scientific studies have reported some seasonal patterns for the macronutrient remobilization in the wooden plant species. Deciduous trees more often store the nutrients in the winter season followed by their remobilization for sustaining leaf growth and plant development. While mature trees only focus on N remobilization during their growth stages. Whereas, in the evergreen trees there is remobilization of Nitrogen and Phosphorus from the leaves.

Micronutrients Remobilization to Reduce Hidden Hunger

Micronutrient remobilization in plants especially for edible plants has gained much less attention. There is an exigent urgent need to focus on this research aspect to improve the micronutrient levels in the edible plant parts. This approach will be efficient and effective to reduce hidden hunger on a sustainable basis.

Role of Flag Leaves for Nutrient Remobilization

Flag leaves and lower leaves in wheat are major sources for remobilization of micronutrients while rice stems account for the Zn remobilization into grains (Wu et al., 2010). Differences in plant anatomy also account for contrasting observations.

Improving Mineral Contents of Grains


“Plants have evolved mechanisms to take up and remobilize nutrients from senescent leaves,” explained senior study author Philippe Ciais, a professor at the University of Paris-Saclay in France. “We show that a similar process occurs when plants take up carbon dioxide from the atmosphere.”

The study found that plants can absorb micronutrients from the air, which helps to improve their nutritional content. This could be an important step in addressing hidden hunger and helping to improve the health of people all over the world.

Requirement of Collaborative Efforts

An exact understanding of the route of minerals translocation. The study of responsible genes is a significant strategy for increasing the flux to seeds resulting in a greater amount of Fe and Zn into seeds. Therefore, there should be good collaboration between international researchers, scientists, and communities to reduce hidden hunger on a sustainable basis. Also Like: Brownian Motion in Chemistry
