1、Brassinosteroids (BRs) Role in Plant Development and Coping with

Brassinosteroids (BRs) are a group of polyhydroxylated steroidal phytohormones that are required for the development, growth, and productivity of plants. These hormones are involved in regulating the division, elongation, and differentiation of numerous cell types throughout the entire plant life cycle.

2、Brassinosteroids: Molecular and physiological responses in plant growth

BRs are the steroidal phytohormones, best known for their role in plant growth and development for the last two decades. The molecular and physiological aspects of BRs under stress condition has resulted in a better understanding. The intrinsic mechanisms concerning these processes are still elusive.

3、Q&A: what are brassinosteroids and how do they act in plants?

Brassinosteroids (BRs) are a class of polyhydroxylated steroidal phytohormones in plants with similar structures to animals’ steroid hormones. Brassinosteroids regulate a wide range of physiological processes including plant growth, development and immunity.

4、Crucial Roles of Brassinosteroids in Cell Wall Composition and

We summarize the outcomes that result from modifying cell wall components by altering BR gene expression, applying exogenous BR and utilizing natural variability in BR content and describing new roles of BR in cell wall structure.

Brassinosteroids and their Biological Activities

Brassinosteroids seem to exert their effects on growth and the cell cycle effects via the cell cycle machinery and apoptosis and may thus be useful leads in the development of novel agents for managing cancer.

Brassinosteroid

Brassinosteroid (BR) is a plant steroid that shows its effect at the micro-level concentration (Kanwar et al., 2017). Its isolation was done from rape pollen (Mitchell et al., 1970).

Brassinosteroid, also known as brassinolide, brassinolide-20-acetate, or brassinolide-20-acetate salt, is a plant growth regulator. As a natural plant-derived hormone, it promotes plant growth and development, enhances stress resistance, increases yield, and improves quality. The effectiveness of brassinosteroid application varies depending on factors such as crop species, varieties, soil conditions, and climate.

1. Timing of Brassinosteroid Application

The optimal time for brassinosteroid application is during the vigorous growth stage of crops, typically starting 20–30 days after sowing. During crop growth, the timing and frequency of application can be adjusted based on plant conditions and needs. Generally, early spring and early summer are ideal periods for application, as higher temperatures facilitate absorption and utilization.

2. Application Methods

There are two main methods for applying brassinosteroid: spraying and foliar application.

• Spraying: Dilute brassinosteroid and spray it onto plants using a sprayer.
• Foliar application: Dilute brassinosteroid and apply it directly to stems and leaves. Choose the appropriate method based on crop type and variety.

3. Application Concentration

The typical concentration is 1–5 ml of brassinosteroid per liter of water. Adjust the concentration according to crop conditions:

• Too high: May cause excessive vegetative growth, reducing yield.
• Too low: May fail to achieve desired effects.

4. Application Frequency

Frequency depends on crop growth stages:

• Early growth: Every 7–10 days.
• Mid-growth: Every 5–7 days.
• Late growth: Every 3–5 days. Increase frequency under adverse conditions (e.g., drought, heat).

5. Effects of Brassinosteroid Application

Effects vary by crop, soil, and climate but generally include:

a) Enhanced Stress Resistance

Improves cold, drought, and pest/disease resistance, reducing damage from natural disasters.

b) Promoted Growth

Stimulates robust growth, photosynthetic efficiency, and dry matter accumulation.

c) Yield Increase

Significantly boosts yield, especially under drought or heat stress.

d) Quality Improvement

Enhances taste, nutritional value, and market value.

6. Precautions

• Select suitable formulations: Choose brassinosteroid types matched to crop varieties.
• Safety: Handle with care (brassinosteroid is a high-toxicity pesticide). Follow dosage guidelines.
• Avoid mixing with other pesticides: Mixing may reduce efficacy or cause adverse reactions.
• Environmental protection: Dispose of leftover product safely. Improve soil fertility through proper farming practices.

The effectiveness of brassinosteroid application depends on crop type, soil, and climate. For optimal results and safety, select appropriate formulations, follow safety protocols, avoid incompatible pesticides, and prioritize environmental protection.
