The Roles of Bacteria and Fungi in Plant Nutrition02:11

The Roles of Bacteria and Fungi in Plant Nutrition

34.8K
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.

Biological Clocks and Seasonal Responses02:45

Biological Clocks and Seasonal Responses

34.5K
The circadian—or biological—clock is an intrinsic, timekeeping, molecular mechanism that allows plants to coordinate physiological activities over 24-hour cycles called circadian rhythms. Photoperiodism is a collective term for the biological responses of plants to variations in the relative lengths of dark and light periods. The period of light-exposure is called the photoperiod.

Management of Insomnia01:19

Management of Insomnia

185
The sleep cycle, an integral part of human health, consists of several stages with distinct characteristics and functions. It begins with a transition from wakefulness to sleep, known as the light sleep phase, followed by the restorative deep sleep phase, essential for physical recovery and growth. The cycle concludes with the Rapid Eye Movement (REM) phase, characterized by high brain activity and vivid dreaming. Insomnia, a prevalent sleep disorder, involves difficulty falling asleep, staying...

Overview of Metabolism01:40

Overview of Metabolism

29.1K
Living cells constantly carry out various chemical reactions which are necessary for their proper functioning. These reactions are interlinked to one another via multiple pathways. The collection of these chemical reactions is known as metabolism.
Plant Metabolism
Sunlight, the primary source of energy in plants, is first absorbed by the chlorophyll pigments present in their leaves. Plants then use this energy to carry out photosynthesis, where water is oxidized into oxygen and carbon dioxide...

Plant Hormones01:56

Plant Hormones

23.1K
Plant hormones—or phytohormones—are chemical molecules that modulate one or more physiological processes of a plant. In animals, hormones are often produced in specific glands and circulated via the circulatory system. However, plants lack hormone-producing glands.

Photoreceptors and Plant Responses to Light02:00

Photoreceptors and Plant Responses to Light

19.9K
Light plays a significant role in regulating the growth and development of plants. In addition to providing energy for photosynthesis, light provides other important cues to regulate a range of developmental and physiological responses in plants.

Area of Science:

  • Plant Science
  • Biochemistry
  • Microbiology

Background:

  • Melatonin is a ubiquitous molecule found across all living organisms.
  • In plants, melatonin functions as a potent antioxidant, crucial for managing biotic and abiotic stresses.
  • Its presence influences numerous physiological processes, including germination, photosynthesis, and senescence.

Purpose of the Study:

  • To summarize the multifaceted roles of melatonin in plant physiology and its interactions with the soil microbiome.
  • To highlight melatonin's benefits for plant growth, development, and stress tolerance.
  • To underscore the reciprocal relationship between plant- and microbe-derived melatonin.

Main Methods:

  • Literature review and synthesis of existing research on melatonin's functions in plants.
  • Analysis of studies investigating melatonin's impact on plant physiological processes.
  • Examination of research on melatonin's influence on soil bacteria and plant-microbe interactions.

Main Results:

  • Melatonin significantly improves seed germination, fruit ripening, photosynthesis, biomass production, and root development.
  • It enhances plant tolerance to biotic and abiotic stresses, prevents leaf senescence, and modulates circadian rhythms.
  • Melatonin influences the soil microbiome, and microbial melatonin can impact plant health and tolerance.

Conclusions:

  • Melatonin is a vital phytohormone with diverse beneficial effects on plant growth, development, and stress response.
