Brassinosteroid (BR), a growth-promoting phytohormone, mitigates various stresses including salt, drought, and extreme temperatures in rice. However, the mechanisms by which BR alleviates salt stress during seed germination remain inadequately characterized.
2、Brassinosteroids: A Promising Option in Deciphering Remedial Strategies
Rice is an important staple crop as it feeds about a half of the earth’s population. It is known to be sensitive to a range of abiotic stresses which result in significant decline in crop productivity. Recently, the use of phytohormones for abiotic ...
3、Brassinosteroid regulation in rice seed biology
Here, we review recent progress into BR regulation in rice seed biology. Both BR biosynthesis and signaling have been shown to regulate grain size, grain filling, grain number, seed germination and biosynthesis of seed components.
(PDF) Brassinosteroid Signaling and Application in Rice
Combined approaches with genetics, biochemistry, and proteomics studies have greatly advanced our understanding of brassinosteroid (BR) signaling in Arabidopsis. However, in rice, a model plant...
Brassinosteroid Signaling and Application in Rice
With more attentions been paid on rice BR studies recently, we will expect a rapid progress on understanding rice BR signaling pathway and further application of the BR knowledge in rice breeding.
Brassinosteroids Regulate Grain Filling in Rice
We created transgenic rice plants expressing maize (Zea mays), rice, or Arabidopsis thaliana genes encoding sterol C-22 hydroxylases that control brassinosteroid (BR) hormone levels using a promoter that is active in only the stems, leaves, and roots.
Foliar cytokinins or brassinosteroids applications influence the rice
A study by Sonjaroon et al. (2018) showed that rice plants treated with an application of 7,8-dihydro-8α-20-hydroxyecdysone (αDHECD, 0.0001 µM) (synthetic brassinosteroid) increased their photosynthetic parameters under heat stress compared to untreated and stressed plants.

Roles of jasmonates and brassinosteroids in rice responses to high
Using JAs or BRs as chemical regulators and adopting proper water and nitrogen management practices could reduce the harm of HT stress to rice.
Analytical Methods for Brassinosteroid Analysis: Recent Advances and
Accurate quantification of BRs in plant tissues is essential for understanding their biological functions. This study presents a comprehensive overview of the latest methods used for the quantification of BRs in plants.
Brassinosteroid (Tianlin) is a plant growth regulator primarily used to promote plant growth, enhance yield, and improve quality. In rice cultivation, applying brassinosteroid effectively stimulates growth, increases productivity, and boosts disease resistance. Below is a detailed guide on methods and dosages for using brassinosteroid in rice:
1. Application Methods
(1) Seed Soaking Method
Soak rice seeds in an appropriate amount of brassinosteroid solution for 24–48 hours, then rinse thoroughly with clean water. This method is suitable for large-scale application.
(2) Spraying Method
Dilute brassinosteroid to the required concentration and apply evenly over rice plants using a sprayer. This method is ideal for targeted treatments.
(3) Root Dipping Method
Mix brassinosteroid solution with rice seeds and dip the seeds in water. This method is designed for root-specific treatments.
2. Dosages
(1) Seed Soaking Method
Dosage varies based on region, rice variety, and growth stage. Generally, 5–10 grams per mu (0.0667 hectare) is recommended.
(2) Spraying Method
Adjust dosage according to planting area, growth stage, and soil moisture. Typically, 200–500 milliliters per mu is sufficient.
(3) Root Dipping Method
Determine dosage based on rice variety, growth stage, and soil conditions. A typical dose is 0.5–1 gram per seedling.
3. Precautions
- Apply in Small Amounts, Multiple Times: Avoid overuse to prevent phytotoxicity.
- Compatibility with Other Treatments: Ensure proper integration with pesticides and fertilizers to avoid adverse reactions.
- Environmental Protection: Prevent contamination of water sources and soil.
- Monitor Crop Response: Discontinue use and consult professionals if abnormalities occur.
select appropriate methods, dosages, and timing based on specific conditions to ensure healthy crop growth and yield improvement. Adhere to regulations and standards for safe, eco-friendly, and efficient agricultural practices.
