1、Brassinolide ameliorates the detrimental effects of arsenic in tomato

Anthropogenic activities, such as manufacturing arsenic (As)-containing pesticides, using fossil fuels, and extracting minerals, lead to the transfer of arsenic into water and soil, resulting in environmental damage (Ghorbani et al., 2024a).

2、Brassinosteroid improves light stress tolerance in tomato (Lycopersicon

We aimed to evaluate the role of brassinosteriod in plants under both high and low light conditions by examining various physiological parameters such as photosynthetic efficiency, pigment levels, and enzymatic activity of various antioxidant enzymes in one month old tomato plants.

3、Brassinolide ameliorates the detrimental effects of arsenic in tomato

<p>The role of brassinosteroids (BRs) in enabling plants to respond effectively to adverse conditions is well known, though the precise mechanism of action that helps plants cope with arsenic (As) toxicity is still difficult to interpret.

Brassinosteroids, such as epibrassinolide (EBL), have multiple actions in essential processes in plants. Thus, the objective of this study was to evaluate the contributions of EBL to the growth,...

Brassinosteroids act as a positive regulator of NBR1

Brassinosteroids (BRs) are steroid phytohormones that play crucial roles in plant response to stresses. Here, we investigate the role of BRs in NBR1-dependent selective autophagy in response to chilling stress in tomato.

Effect of brassinosteroids on drought resistance and abscisic acid

Our study suggested that amelioration of the drought stress of tomato seedlings may be caused by EBR-induced elevation of endogenous ABA concentration and/or the activities of antioxidant enzymes. Yuan, G.F.; Jia, C.G.; Li, Z.; Sun, B.; Zhang, L.P.; Liu, N.; Wang, Q.M.

BRs have been shown in numerous studies to have a positive impact on plant responses to various biotic and abiotic stresses.

Effects of brassinosteroids on quality attributes and ethylene

Effects of brassinosteroids (BRs) on postharvest ripening of tomato fruit were studied in this work. Mature green tomato fruit were harvested and treated with brassinolide (BL, the most active brassinosteroid) or brassinazole (BRZ, a brassinosteroid biosynthesis inhibitor).

Regulatory role of exogenous 24

EBR treatment has a significant effect on key qualities such as vitamin C, sugar components, and flavonoids in tomatoes, while Brz has the opposite effect. Overall, EBR treatment was more effective in promoting the content of important quality indicators in tomatoes than CK and Brz treatments.

Brassinosteroids are a type of plant growth regulator that significantly impacts the growth and development of tomatoes. Below is a detailed explanation of their effects:

1. Promote Growth and Development: Brassinosteroids stimulate tomato plant growth by accelerating growth rates. This is primarily due to their ability to promote cell division and elongation, thereby speeding up plant development. Additionally, they enhance fruit enlargement, resulting in fuller, more vibrantly colored tomatoes.

2. Improve Stress Resistance: Brassinosteroids enhance the plant’s disease and pest resistance by inhibiting pathogen and insect growth, reducing the likelihood of infections or infestations. They also strengthen drought and waterlogging tolerance, enabling plants to thrive under adverse environmental conditions.

3. Enhance Fruit Quality: Brassinosteroids improve tomato fruit quality. For example, they increase sugar content, enhancing taste; enrich fruit color, making them more visually appealing; and boost fruit firmness, improving storage and transport durability.

4. Increase Yield: Brassinosteroids boost tomato yields by enhancing nutrient absorption and utilization, improving photosynthetic efficiency, and promoting fruit enlargement. This results in larger, more abundant harvests.

5. Extend Shelf Life: Brassinosteroids prolong tomato freshness by suppressing ethylene production and reducing respiration rates, which slows fruit aging. They also enhance antioxidant capacity, protecting fruits from oxidative damage during storage.

6. Facilitate Flower Bud Differentiation: Brassinosteroids stimulate the development of the reproductive system, promoting flower bud formation and differentiation. They also aid pollen dispersal and pollination, improving fruit-setting rates.

7. Promote Root Development: Brassinosteroids encourage robust root growth by stimulating root proliferation and length. This enhances nutrient uptake, ensuring plants receive ample soil nutrients for healthy growth.

8. Strengthen Cold Resistance: Brassinosteroids improve cold tolerance by enhancing frost resistance, allowing plants to maintain normal growth in low-temperature environments. They also increase wind resistance, stabilizing plants during harsh weather.

9. Accelerate Early Maturation: Brassinosteroids accelerate tomato ripening by speeding up growth rates and shortening maturation time. They also elevate sugar levels, enabling fruits to mature quickly while retaining quality.

10. Boost Economic Efficiency: By increasing yield and quality, brassinosteroids significantly enhance agricultural profitability. They reduce production costs by minimizing pest and disease risks, delivering greater returns for farmers.

As a novel plant growth regulator, brassinosteroids have multifaceted benefits for tomato cultivation. Proper use can substantially improve yield, quality, and economic outcomes. careful attention must be paid to dosage and application methods to avoid environmental or human health risks.
