Summary
Biological control using Trichoderma offers a sustainable alternative to agrochemicals for managing fungal plant pathogens, enhancing crop yield and food security. This review explores Trichoderma
Area of Science:
- Agricultural Science
- Plant Pathology
- Microbiology
Background:
- Fungal plant pathogens cause significant pre-harvest crop losses globally.
- Agrochemical use for control poses risks to human health and the environment.
- Biological control agents (BCAs) offer a safer, ecosystem-compatible alternative.
Purpose of the Study:
- To review the interactions between Trichoderma, fungal pathogens, and plants pre-harvest.
- To highlight the influence of these interactions on crop production and food security.
- To explore future crop protection strategies.
Main Methods:
- Review of scientific literature on Trichoderma and plant-pathogen interactions.
- Analysis of Trichoderma's biocontrol mechanisms (antibiosis, mycoparasitism).
- Discussion of plant-growth promotion and stress tolerance effects.
Main Results:
- Trichoderma spp. effectively control fungal pathogens through direct antagonism and by enhancing plant defense.
- Trichoderma promotes plant growth and improves tolerance to abiotic stresses.
- These interactions are crucial for maintaining crop yield and ensuring food security.
Conclusions:
- Trichoderma represents a promising biological control strategy against fungal plant diseases.
- Understanding Trichoderma-plant-pathogen interactions is key to sustainable agriculture.
- Future strategies include advanced methods like antimicrobial peptides and engineered plant resistance.

01:26Pharmacokinetics: Drug–Food and Drug–Viral Interactions
222
A drug interaction occurs when the concurrent use of another drug, food, or an external substance alters the pharmacological activity of a drug. This interaction can modify the action of the original drug, affecting its effectiveness and safety.Drug–food interactions are significant as they impact drug absorption, metabolism, and excretion. For example, grapefruit juice is a well-known disruptor of drug metabolism. It inhibits the cytochrome P450 3A4 enzyme, crucial for the metabolism of...

02:11The Roles of Bacteria and Fungi in Plant Nutrition
47.1K
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.

02:01Plant Cells and Tissues
65.2K
Plant tissues are collections of similar cells performing related functions. Different plant tissues will have their own specialized roles and can be combined with other tissues to form organs such as flowers, fruit, stem, and leaves. Two major types of plant tissue include meristematic and permanent tissue.

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.

02:01pre-mRNA Processing
57.2K
In eukaryotic cells, transcripts made by RNA polymerase are modified and processed before exiting the nucleus. Unprocessed RNA is called precursor mRNA or pre-mRNA to distinguish it from mature mRNA.
Once about 20-40 ribonucleotides have been joined together by RNA polymerase, a group of enzymes adds a “cap” to the 5’ end of the growing transcript. In this process, a 5’ phosphate is replaced by modified guanosine that has a methyl group attached to it (7-Methyl...

00:53Tonicity in Plants
59.7K
Tonicity describes the capacity of a cell to lose or gain water. It depends on the quantity of solute that does not penetrate the membrane. Tonicity delimits the magnitude and direction of osmosis and results in three possible scenarios that alter the volume of a cell: hypertonicity, hypotonicity, and isotonicity. Due to differences in structure and physiology, tonicity of plant cells is different from that of animal cells in some scenarios.
