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.

Brassinosteroids in growth control: How, when and where

In this review, we outline the evolution of brassinosteroid research, discuss the contribution of whole-plant-based and the more recent tissue-specific-based approaches and highlight a recently reported mechanism controlling spatial distribution of brassinosteroids.

Editorial: An Update on Brassinosteroids: Homeostasis, Crosstalk, and

Over the last three decades, there have been significant advances in the understanding of brassinosteroid (BR) biosynthesis and signaling, particularly in the model plant species Arabidopsis thaliana.

Understanding brassinosteroid

Brassinosteroids (BRs) play a crucial role in regulating multiple biological processes in plants, particularly those related to crop productivity and stress tolerance.

Brassinosteroid signaling in plant development and adaptation

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, also known as brassinin or phytosulfokine, is a natural plant growth regulator widely used in agriculture, horticulture, and floriculture. It promotes plant growth, enhances stress resistance, and increases crop yields. For osmanthus, applying brassinosteroid significantly improves growth rates and flowering quality. Below, we explore its effects and applications in detail.

1. Mechanism of Action

Brassinosteroid mimics endogenous hormones like gibberellin, influencing cell elongation, division, and differentiation to stimulate plant growth. When applied to osmanthus, it may act through the following pathways:

• Root Development: Stimulates root growth, enhancing water and nutrient absorption.
• Leaf Expansion: Accelerates leaf expansion, improving photosynthetic efficiency.
• Flower Bud Differentiation: Promotes flower bud formation, advancing the flowering period.

2. Optimal Timing for Application

To maximize effectiveness, timing is critical. Apply brassinosteroid early in the growing season, typically when osmanthus resumes growth in spring. At this stage, plants are more adaptable to environmental conditions, allowing better absorption and efficacy.

3. Application Methods and Dosage

Methods

Application methods include spraying, drip irrigation, and root injection. Choose the method based on specific needs:

• Spraying: Common for large osmanthus gardens.
• Drip Irrigation: Suitable for potted or container-grown plants.
• Root Injection: Used for mature roots or special cases.

Dosage Control

Adjust dosage based on plant size, growth stage, and soil conditions. For first-time use, follow the manufacturer’s recommendations and refine based on observed effects. Excessive use may cause rapid, unbalanced growth or adverse effects.

4. Post-Application Care

After spraying, take note of:

• Monitoring Responses: Observe for abnormalities (e.g., leaf discoloration, uneven growth) and adjust protocols if needed.
• Avoid Overdosing: Stick to recommended doses to prevent damage.
• Continuous Tracking: Regularly monitor growth and environmental factors to optimize results.

5. Integrated Management and Effectiveness Evaluation

Combine brassinosteroid application with other practices, such as balanced fertilization, irrigation, and pest control. Periodically assess outcomes to refine strategies. Scientific management and proper application can significantly enhance osmanthus quality and bloom quantity, improving aesthetic appeal for gardening enthusiasts.

Brassinosteroid spraying is a promising approach for osmanthus cultivation, but success requires careful management and scientific application. By optimizing timing, methods, and monitoring, its benefits can be fully leveraged to promote healthy growth and superior flowering.
