1、Engineering brassinosteroids pathway: a key strategy for enhancing crop
Effective manipulation of BR to leverage its positive benefits while mitigating adverse effects holds the prospect of significantly enhancing yield (Tong and Chu 2018).
2、Brassinosteroids: Molecular and physiological responses in plant growth
Brassinosteroids improves crop yields by altering plant metabolism and protecting plants from several abiotic stresses. Brassinosteroids regulate gene expression and signal transduction pathways to stimulate abiotic stress tolerance.
3、Understanding brassinosteroid
In this review, we introduce BR metabolism and signaling and discuss their role in modulating agronomic traits that directly contribute to grain yield in rice (Oryza sativa), the model plant for crops.
4、Brassinosteroids in cotton: orchestrating fiber development
Manipulating BR genes through molecular design offers the potential for enhancing cotton yield and quality. Further, the mechanisms of cell expansion in cotton are mainly governed by water uptake and changes in the extensibility of the cell wall.

The tissue-specific activation of BRD3 in the secondary branch meristems enhances panicle branching, minimizing negative effects on grain size, and improves grain yield.
Brassinosteroids: The promising plant growth regulators on vegetable
This table provides a concise overview of how brassinosteroids impact various critical aspects of vegetable crop production, focusing on their role in promoting growth, enhancing yield, and mitigating abiotic stresses.
Foliar applied brassinosteroids significantly enhanced cotton yield in
Brassinosteroids, as high-efficiency broad-spectrum plant growth regulators, have the effect of promoting growth, stress resistance and yield increment (Ahammed et al. 2020; Bajguz and Hayat 2009; Bajguz and Tretyn 2003).
Enhancing rice panicle branching and grain yield through tissue
Brassinosteroids (BRs), a class of steroid hormones, promote grain size and have been demonstrated to enhance crop yield. Despite their potential, the pleiotropic effects of BRs have hindered their use in crop improvement, and their role in regulating grain number remains unclear.
Application of brassinosteroids for improving crop production: from
BRs (BL, HBL, and EBL) can not only increase the yield of plants but also improve the quality of products, which is manifested in a decrease in nitrate content and an increase in starch and vitamin C (Khripach et al., 2000).
Brassinosteroids: An Innovative Compound Family That Could Affect the
This review revealed that 24-epibrassinolide is the most used BR analogue in research experiments, either as a pre- or postharvest treatment, with doses ranging from 0.1 to 15 μM. Additionally, most of the research has been conducted on non-climacteric fruit species.
1. Mechanism of Action of Brassinosteroids
Brassinosteroids primarily inhibit the activity of abscisic acid (ABA) synthase in plants, reducing ABA production while increasing the synthesis of cytokinins (e.g., gibberellins, auxins). Cytokinins stimulate cell elongation and differentiation, accelerating growth rates and stress resistance. Additionally, brassinosteroids enhance photosynthesis, improve pest/disease resilience, and optimize resource utilization.
2. Applications in Agriculture
As a highly efficient growth regulator, brassinosteroids are widely used across crops:
- Cereals (wheat, corn, soybeans): Increase per-unit yields and total output.
- Oilseeds (cotton, rapeseed): Promote leaf development, photosynthetic capacity, and seed yield.
- Fruit Trees: Enhance fruit development and quality.
3. Advantages of Brassinosteroids for Yield Enhancement
Compared to other plant growth regulators, brassinosteroids offer:
- High Efficiency: Rapid results (within one week of application) in growth acceleration and yield improvement.
- Safety: Low toxicity to humans/animals, minimal environmental pollution, and reduced residue risks compared to chemical pesticides.
- Cost-Effectiveness: Competitive pricing and ease of application facilitate widespread adoption.
4. Limitations of Brassinosteroids
Despite their benefits, limitations include:
- Crop-Specific Suitability: More effective for sun-loving, drought-resistant crops requiring enhanced photosynthesis; less impactful for shade-tolerant or disease-prone crops.
- Short-Term Action: Effects peak within one week post-application, requiring timely dosing aligned with growth stages.
- Resistance Risks: Excessive/prolonged use may reduce pathogen sensitivity. Dosage and frequency control are critical.
5. Comprehensive Evaluation
Brassinosteroids are a promising tool for sustainable agriculture due to their potent yield-boosting effects and eco-friendly profile. optimizing usage requires addressing crop-specific constraints, timing challenges, and resistance management. With careful implementation, they can support healthy crop development and long-term agricultural viability.
Note on Terminology: The term "Bactoclavulan" appears unconventional for brassinosteroids. Common scientific names include brassinolide or general references to "brassinosteroids." If this term refers to a specific commercial product, please verify the accurate name for precise translation.
