1、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 ...

2、Can Brassinosteroids Be Used Before Transplanting Rice Seedlings? Why?

Brassinosteroid (BR) enhances the salt tolerance of rice seeds by improving their antioxidant capacity during germination. Five genes and two metabolites have been identified as key contributors to this process.

3、Frontiers

Brassinosteroids (BRs), the sixth class of plant hormones identified after gibberellins, ethylene, auxins, abscisic acid, and cytokinins, play pivotal roles in plant growth and development.

4、Brassinosteroid regulation in rice seed biology

In higher plants, brassinosteroid (BR), a major growth-promoting hormone, plays an important role in regulating numerous agronomic traits associated with both vegetative and reproductive growth, thereby presenting huge application potential.

Multi

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.

The Effects of Brassinosteroids on Nitrogen Utilization in Rice

The results showed that BR treatment could efficiently elevate nitrate and ammonium nitrogen accumulation in both shoots and roots. Furthermore, some genes involved in the uptake of nitrate and ammonium in roots were stimulated by BRs, though we noted subtle variances between the two rice cultivars.

Brassinosteroid

In this review, we provide an update on the progress made by BR studies in rice and discuss how BR regulates various important agronomic traits to determine rice grain yield.

Root

Concurrently, WMD facilitated photosynthate allocation from vegetative tissues to grains, collectively improving rice yield. Collectively, our data suggest that the WMD practices can effectively reduce CH 4 emissions, GWP, and GHGI in rice paddies while maintaining high grain yield by stimulating root-derived BR biosynthesis.

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 of monocot and as well an important crop plant, BR signaling is not as well characterized as in Arabidopsis.

Hybrid rice is a rice variety developed through artificial selection or natural variation, characterized by heterosis (hybrid vigor). This advantage manifests in several key aspects:

1. Enhanced Resistance to Pests and Diseases: The genetic combination of hybrid rice enables the expression of certain disease- and pest-resistant traits, strengthening its resilience against various pathogens and insects.

2. Increased Yield: Due to genetic diversity, hybrid rice exhibits faster growth rates and improved photosynthetic efficiency, resulting in significantly higher yields.

3. Improved Quality: Hybrid rice often shows better taste, appearance, and grain characteristics, such as fuller grains and brighter color.

4. Strong Adaptability: Hybrid rice thrives in diverse environmental conditions, including varied soil types and climates.

5. Resource Efficiency: High seed utilization rates reduce waste compared to traditional varieties.

developing hybrid rice requires substantial human, material, and time resources. Improving production efficiency and reducing costs have become critical research priorities.

Brassinosteroid soaking is a novel plant growth regulator primarily used to promote plant growth and enhance stress resistance. Recent studies show that brassinosteroids stimulate root development and improve nutrient uptake, benefiting early plant growth.

For hybrid rice, brassinosteroid soaking can boost germination rates and seedling survival. This is because brassinosteroids enhance root growth and nutrient absorption, enabling seeds to access soil nutrients more effectively. Additionally, brassinosteroids inhibit ethylene production, slowing growth progression and aiding survival under adverse conditions (e.g., high temperatures or drought). This is particularly valuable for hybrid rice, which may face environmental challenges during cultivation.

hybrid rice can benefit from brassinosteroid soaking. The treatment improves germination and seedling survival by promoting root development and nutrient uptake, while also enhancing stress resistance by regulating ethylene levels.
