Microorganisms in Agriculture and Food industry

96
Microorganisms play a crucial role in agriculture and the food industry, contributing to soil fertility, crop protection, and food production. Their functions range from nitrogen fixation and biopesticide production to fermentation and food preservation, making them indispensable to sustainable farming and food safety.Role in AgricultureNitrogen-fixing bacteria, such as Rhizobium (symbiotic) and Azotobacter (free-living), convert atmospheric nitrogen into ammonia through biological nitrogen...

Plant Breeding and Biotechnology

19.5K
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.

Key Elements for Plant Nutrition

18.9K
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...

Responses to Salt Stress

13.2K
Salt stress—which can be triggered by high salt concentrations in a plant’s environment—can significantly affect plant growth and crop production by influencing photosynthesis and the absorption of water and nutrients.

The Roles of Bacteria and Fungi in Plant Nutrition

36.3K
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.

Summary

Global food systems face insecurity due to declining biodiversity. Diversifying with neglected and underutilized species is key, but clear definitions are needed for effective use of these valuable crops.

Area of Science:

  • Agricultural Science
  • Food Security
  • Biodiversity Conservation

Background:

  • Global food systems are increasingly homogenized, relying on a few commodity crops.
  • This homogenization leads to decreased biodiversity and dietary diversity, impacting food and nutrition security.
  • The United Nations and FAO advocate for diversifying food systems with neglected and underutilized species (NUS).

Purpose of the Study:

  • To clarify the definitions and usage of terms associated with neglected and underutilized species.
  • To address the confusion surrounding these crops, hindering their economic potential and utilization.
  • To facilitate better inter-sector communication and policy development regarding crop diversification.

Main Methods:

  • A systematic literature review and linguistic corpus search were conducted.
  • Six key terms were analyzed: ancient, heirloom, heritage, traditional, orphan, and landrace.
  • Critical Discourse Analysis was employed to interpret the findings.

Main Results:

  • Definitions for heirloom, heritage, and ancient crops emphasize family lineage and naturalization (primarily in the UK/USA).
  • 'Orphan crops' are characterized by being overlooked by growers and underfunded by researchers.
  • 'Landrace' is strongly linked to locality, biocultural diversity, indigenous origins, and genomics.
  • Most terms were found to be evolving and context-dependent, with 'landrace' being the most distinct.

Conclusions:

  • A lack of clear, consistent definitions for terms like 'heirloom,' 'heritage,' and 'orphan' crops hinders their integration into global food systems.
  • The term 'landrace' shows stronger ties to specific biological and cultural contexts.
  • The study provides 58 definitions and key terms to improve communication and policy for utilizing diverse crop resources.
