Brassinosteroids (BRs) are an important group of plant hormones involved in regulating plant growth and development, and they help plants to adapt to the environment [7].

Regulation of Brassinosteroid Homeostasis in Higher Plants

Although application of limited amounts of BRs can significantly enhance growth, excessive BRs are usually harmful to plant growth and development (Clouse et al., 1996). Maintenance and regulation of endogenous BR levels are therefore essential for optimal plant growth and development.

Brassinolides are natural plant hormones primarily found in cruciferous plants such as Brassica oleracea (rapeseed) and Brassica juncea (mustard). They play a crucial role in regulating plant growth and development. Below is a detailed explanation of how brassinolides modulate plant growth rates:

1. Promoting Cell Division

Brassinolides stimulate cell division in plants, thereby increasing cellular volume and quantity. This effect is achieved by activating specific enzymes within the plant. When brassinolides bind to receptors on the plasma membrane of plant cells, they trigger a cascade of signal transduction processes that accelerate the cell cycle. This enables plants to grow rapidly within limited timeframes, enhancing their survival and reproductive opportunities.

2. Inhibiting Auxin Synthesis

Brassinolides also suppress the synthesis of auxin, another key plant hormone. While auxin is essential for growth, excessive levels can lead to overly rapid growth or abnormal development. By inhibiting auxin production, brassinolides help maintain balanced growth rhythms and prevent excessive elongation.

3. Regulating Photosynthesis

Brassinolides influence photosynthetic efficiency by enhancing chloroplast activity in plant leaves. This allows plants to convert carbon dioxide into oxygen and organic matter more effectively. Additionally, brassinolides alter plant responses to light, such as sensitivity to light intensity and duration, further optimizing photosynthetic performance.

4. Enhancing Nutrient Uptake and Transport

Brassinolides improve the absorption and transport of nutrients, accelerating growth. Research shows they increase the root system’s ability to absorb soil nutrients while facilitating nutrient distribution throughout the plant. This boosts resource utilization and supports robust growth.

5. Balancing Phytohormone Levels

Brassinolides regulate plant growth by modulating hormonal balance. For example, they reduce levels of auxin and gibberellins, adjusting growth direction and speed. This hormonal fine-tuning helps plants adapt to environmental fluctuations, ensuring stable and efficient development.

6. Improving Stress Resistance

Brassinolides enhance a plant’s ability to withstand abiotic stresses like drought, salinity, and pest/disease attacks. By strengthening resilience to adverse conditions, they enable plants to survive and continue growing in challenging environments.

brassinolides regulate plant growth rates through multiple pathways: promoting cell division, inhibiting auxin synthesis, optimizing photosynthesis, enhancing nutrient uptake, balancing hormones, and improving stress resistance. These mechanisms position brassinolides as a critical tool in agricultural production for manipulating plant growth.
