The Roles of Bacteria and Fungi in Plant Nutrition02:11

The Roles of Bacteria and Fungi in Plant Nutrition

35.5K
Plants have the impressive ability to create their own food through photosynthesis. However, plants often require assistance from organisms in the soil to acquire the nutrients they need to function correctly. Both bacteria and fungi have evolved symbiotic relationships with plants that help the species to thrive in a wide variety of environments.

Key Elements for Plant Nutrition02:35

Key Elements for Plant Nutrition

18.8K
Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...

Vitamins01:30

Vitamins

730
Vitamins, derived from the Latin word for life, are essential organic substances required in small quantities for optimal growth and overall well-being. Unlike other organic nutrients, vitamins don't act as sources of energy or building materials but rather facilitate these nutrients' utilization by the body. Vitamins are predominantly coenzymes, assisting enzymes in specific chemical actions, like the oxidation of glucose for energy involving B vitamins. Most vitamins are not produced...

Minerals

313
Minerals are essential nutrients that the human body needs in small amounts to work properly. They play a vital role in many bodily functions, such as building strong bones and transmitting nerve impulses. Some minerals are needed for hormone production or to maintain a normal heartbeat. Major minerals include calcium, phosphorus, potassium, sulfur, sodium, chlorine, and magnesium, while trace minerals include iron, manganese, copper, iodine, zinc, cobalt, fluoride, and selenium.

Plant Breeding and Biotechnology

18.9K
Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy

334
Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Area of Science:

  • Agricultural Science
  • Nutritional Science
  • Public Health

Background:

  • Biofortification emerged in the 1990s as a sustainable approach to address micronutrient malnutrition.
  • The scope of biofortification has expanded beyond staple crops and low-income economies.
  • Micronutrient malnutrition remains a significant global health challenge, often termed 'hidden hunger'.

Purpose of the Study:

  • To review the achievements of biofortification in its original context.
  • To identify limitations hindering the efficacy of biofortified crops in improving micronutrient status.
  • To advocate for the inclusion of biofortified crops with provitamin D3/vitamin D3, vitamin B12, and iron for new demographic needs.
  • To explore the integration of biofortification into the global food system for improved nutrition and sustainable agriculture.

Main Methods:

  • Literature review and synthesis of existing research on biofortification.
  • Analysis of factors limiting the effectiveness of biofortified crops.
  • Case highlighting specific micronutrients (provitamin D3/vitamin D3, vitamin B12, iron) and target populations.
  • Exploration of integration strategies within global food systems.

Main Results:

  • Biofortification has demonstrated success in enhancing nutrient content of staple crops.
  • Key limiting factors include bioavailability, crop-specific efficacy, and consumer acceptance.
  • Emerging needs highlight the potential for biofortified crops rich in vitamin D3, B12, and iron.
  • Integration into food systems requires multi-stakeholder collaboration and supportive policies.

Conclusions:

  • Biofortification is a vital strategy for combating hidden hunger and improving global nutrition.
  • Expanding biofortification to include diverse micronutrients and target populations is crucial.
  • Successful integration requires addressing bioavailability, policy, and systemic challenges.
  • Biofortification contributes to both improved health outcomes and sustainable agricultural practices.
