1、Roles of Brassinosteroids in Mitigating Heat Stress Damage in Cereal

Brassinosteroids (BR) are a class of plant hormones that impact tolerance to various biotic and abiotic stresses and regulate cereal growth and fertility. Fine-tuning the action of BR has the potential to increase cereals’ tolerance and acclimation to heat stress and maintain yields.

2、Brassinosteroids alleviate wheat floret degeneration under low nitrogen

Brassinosteroids mitigate wheat floret degeneration by promoting carbohydrate redistribution from stems to spikes. The trade-off between yield and environmental effects caused by nitrogen fertilizer application is an important issue in wheat production.

3、Growth

It was shown that treatment of plants by spraying with brassinosteroids or ferulic acid led to the activation of growth processes, the productivity of morphogenesis and reproduction, and an increase in the level of endogenous brassinosteroids, free radical oxidation, and pigments.

The cost of brassinosteroids is brought down to affordable levels and the chemical promise held by brassinosteroids to improve crop yields could be soon accomplished.

Effects of exogenous brassinosteroids on the starch structure

Therefore, a two-year field experiment was carried out from 2020 to 2022 to explore the effects of exogenous BRs spraying on the wheat yield, morphological structure and physicochemical properties of starch under high-temperature stress at the early grain-filling stage.

Brassinosteroid Regulates Root Development with Highly Redundant Genes

Our findings demonstrated that BR has a conserved function in regulating root length in wheat, and novel roles in regulating lateral root emergence and root diameter were uncovered.

Brassinosteroids improve the redox state of wheat florets under low

Brassinosteroids optimize carbon allocation in the tricarboxylic acid cycle (TCA) cycle and boost adenosine triphosphate (ATP) to reduce floret degeneration. Reducing nitrogen application rates can mitigate issues such as environmental degradation and resource wastage.

Over-application of brassinosteroid (a plant growth regulator) in wheat fields can lead to a series of negative effects, impacting crop growth and yield. The following analysis details the potential consequences:

1. Suppressed Plant Growth:

   • Brassinosteroid, a hormone that promotes plant growth, can inhibit normal development when used excessively. In wheat fields, this may slow seedling growth, weaken stems, and reduce stress resistance.
   • Plants may become stunted, exhibit reduced tillering, or develop abnormalities such as distorted leaves and irregular ears, severely compromising overall health and productivity.

2. Disrupted Pollination and Fruiting:

   • Excessive brassinosteroid can interfere with pollen transmission and tube elongation, disrupting fertilization.
   • Poor pollination hinders seed development, lowers grain quality, reduces kernel count, and ultimately decreases yield.

3. Soil Degradation:

   • Residual brassinosteroid in soil may harm microbial communities, disrupting ecological balance.
   • Reduced beneficial microorganisms impair nutrient cycling, diminish soil fertility, and weaken root systems.

4. Chemical Residue Risks:

   • As a chemical compound, excessive brassinosteroid accumulates in plants and may enter the food chain, posing health risks to humans.
   • Residues on edible crops could violate safety standards, endangering consumer health.

5. Reduced Crop Quality:

   • Overuse may lead to poorer appearance, such as faded color or inferior taste.
   • Inadequate cleanup after application could also affect storage and transportation quality.

6. Environmental Hazards:

   • Excessive use may exacerbate pollution, as brassinosteroid breakdown releases toxic byproducts.
   • These substances can contaminate air, water, and ecosystems, causing long-term damage.

7. Increased Economic Costs:

   • Yield losses, quality declines, and potential pest/disease outbreaks may require additional labor and resources for management, raising production costs.
   • Prolonged overuse could significantly reduce farmers’ income.

8. Regulatory and Legal Risks:

   • Exceeding recommended dosages may violate agricultural laws, leading to fines or legal penalties.
   • Stricter regulatory oversight might be imposed to ensure safe and sustainable farming practices.

9. Weakened Crop Resilience:

   • Long-term overreliance on brassinosteroid could create dependency, leaving crops vulnerable if usage is stopped.
   • This dependency may reduce adaptability to environmental changes, increasing agricultural risks.

Over-applying brassinosteroid in wheat fields poses severe risks, including suppressed growth, pollination failure, soil degradation, chemical residues, quality loss, environmental harm, economic burdens, legal issues, and reduced crop resilience. To safeguard crop health and food safety, farmers must adhere to regulations and guidelines, using plant growth regulators like brassinosteroid judiciously.
