Multifunctional role of brassinosteroid and its analogues in plants

Brassinosteroids (BRs) are steroid hormones that are essential for plant growth and development. These hormones control the division, elongation and differentiation of various cell types throughout the entire plant life cycle.

Brassinosteroid (Tiancai) is a plant growth regulator with significant physiological activity, widely used in agriculture, horticulture, and forestry. Its primary functions and effects include promoting plant growth, enhancing stress resistance, increasing yield, and improving quality. Below is a detailed overview of its roles and benefits:

1. Promoting Plant Growth: Brassinosteroid significantly accelerates plant growth rates, boosting biomass and productivity. In agricultural production, its application effectively shortens crop growth cycles, reducing production costs. Additionally, it stimulates root development, enhancing water and nutrient absorption, which further increases yields.

2. Enhancing Stress Resistance: Brassinosteroid strengthens plants’ ability to resist diseases, pests, drought, and cold. By reducing pest and disease incidence, it lowers pesticide usage, mitigating environmental pollution. It also improves crops’ adaptability to adverse conditions, ensuring robust growth under harsh environments.

3. Increasing Yield: Brassinosteroid application markedly boosts crop yields. Studies show that it raises the yields of staple grains such as wheat, corn, and rice by 10%–20%, 15%–25%, and 10%–20%, respectively. Economic crops like cotton, peanuts, and tobacco also benefit from increased productivity.

4. Improving Quality: Beyond yield gains, brassinosteroid enhances crop nutritional value. For example, it elevates protein, fat, and sugar content in crops. Additionally, it improves texture, color, and flavor, enhancing market competitiveness.

5. Boosting Photosynthesis: Brassinosteroid promotes photosynthesis by increasing photochemical efficiency. Research indicates that it raises photosynthetic rates and leaf area, optimizing energy capture for robust plant development.

6. Delaying Senescence: Brassinosteroid slows plant aging by activating antioxidant enzymes. As plants age, declining antioxidant activity accelerates cell senescence. Brassinosteroid counteracts this, prolonging vitality and lifespan.

7. Protecting the Ecology: By reducing pesticide and fertilizer reliance, brassinosteroid minimizes environmental pollution. Its stress-resistant properties lower crop losses, while reduced synthetic chemical use lessens agricultural runoff, supporting ecological conservation.

8. Balancing Phytohormones: Brassinosteroid regulates endogenous hormone levels, maintaining equilibrium. Studies show it modulates auxins, gibberellins, and cytokinins, fostering healthy growth and development.

Brassinosteroid offers diverse physiological benefits and significant agricultural advantages. Proper application can elevate crop quality and quantity, reduce costs, protect ecosystems, and advance sustainable farming. careful dosage and usage are critical to avoid phytotoxicity or overuse issues.
