Epiphytes, Parasites, and Carnivores

13.1K
Plants often form mutualistic relationships with soil-dwelling fungi or bacteria to enhance their roots’ nutrient uptake ability. Root-colonizing fungi (e.g., mycorrhizae) increase a plant’s root surface area, which promotes nutrient absorption. While root-colonizing, nitrogen-fixing bacteria (e.g., rhizobia) convert atmospheric nitrogen (N2) into ammonia (NH3), making nitrogen available to plants for various biological functions. For example, nitrogen is essential for the...

Trophic Efficiency00:46

Trophic Efficiency

20.7K
Trophic level transfer efficiency (TLTE) is a measure of the total energy transfer from one trophic level to the next. Due to extensive energy loss as metabolic heat, an average of only 10% of the original energy obtained is passed on to the next level. This pattern of energy loss severely limits the possible number of trophic levels in a food chain.

The Roles of Bacteria and Fungi in Plant Nutrition

36.2K
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.

Symbiosis00:58

Symbiosis

28.8K
Symbiotic relationships are long-term, close interactions between individuals of different species that affect the distribution and abundance of those species. When a relationship is beneficial to both species, this is called mutualism. When the relationship is beneficial to one species but neither beneficial nor harmful to the other species, this is called commensalism. When one organism is harmed to benefit another, the relationship is known as parasitism. These types of relationships often...

Defenses Against Pathogens and Herbivores

23.8K
Plants present a rich source of nutrients for many organisms, making it a target for herbivores and infectious agents. Plants, though lacking a proper immune system, have developed an array of constitutive and inducible defenses to fend off these attacks.

Transgenic Plants02:50

Transgenic Plants

7.3K
Recombinant DNA technology called transgenesis is often used to add a foreign gene or remove a detrimental gene from an organism. Such genetically modified organisms are called transgenic organisms.
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...

Area of Science:

  • Plant Science
  • Microbiology
  • Ecology

Background:

  • Plants are not solitary organisms but complex ecological entities known as plant holobionts.
  • The composition of plant-associated microbiota is influenced by host, microbial, and environmental factors.
  • Plant immune responses and microbial interactions shape microbiota assembly.

Purpose of the Study:

  • To explore the concept of plant holobionts and the co-evolutionary dynamics within plant-microbe communities.
  • To understand how plants recruit and interact with beneficial microorganisms.
  • To elucidate the role of microbial antagonism in disease prevention within the holobiont.

Main Methods:

  • Conceptual analysis of plant-microbe interactions and co-evolution.
  • Review of plant immune signaling and metabolite-mediated recruitment strategies.
  • Examination of microbial interdependencies and antagonistic activities.

Main Results:

  • Complex plant-microbe and intermicrobial interactions are evolutionarily selected traits promoting holobiont fitness.
  • Plants utilize metabolite-mediated strategies to selectively recruit beneficial microbes.
  • Microbial co-evolution leads to antagonistic activities that prevent disease and enhance plant performance.

Conclusions:

  • The plant holobiont framework provides a comprehensive view of plant-microbe interactions.
  • Co-evolution within holobionts is a key driver of plant health, resilience, and overall performance.
  • Understanding these intricate relationships is crucial for agricultural and ecological applications.
