Other claims from this paper (17)
- Intervention effect Foliar brassinolide increased silk length by 2.9-fold compared with the stress control.
- Intervention effect Brassinolide partially restored silk elongation under water-deficit stress at 0.1 and 0.5.
- Intervention effect The highest brassinolide concentration suppressed silk elongation under water-deficit stress.
- Intervention effect Brassinolide elevated POD activity by 31–77% relative to distilled water-sprayed plants.
- Intervention effect Brassinolide elevated SOD activity by 12–46% relative to distilled water-sprayed plants.
- Intervention effect Brassinolide elevated CAT activity by 20–33% relative to distilled water-sprayed plants.
- Intervention effect Brassinolide raised proline by 25–76% relative to distilled water-sprayed plants.
- Intervention effect Brassinolide reduced O2− and H2O2 levels by 36–67% relative to distilled water-sprayed plants.
- Intervention effect Brassinolide decreased MDA content by 24% relative to distilled water-sprayed plants.
- Intervention effect Brassinolide reduced sucrose phosphate synthase (SPS) activity.
- Intervention effect Brassinolide increased sucrose synthase (SS-I) and vacuolar invertase (VIN) activities.
- Observation Genome-wide RNA-seq identified 6171 upregulated genes.
- Observation Genome-wide RNA-seq identified 3295 downregulated genes.
- Observation Gene expression was significantly enriched in 20 pathways, including starch/sucrose metabolism, glycolysis/gluconeogenesis and phenylpropanoid biosynthesis.
- Intervention effect Brassinolide upregulated sucrose invertase (INV) expression by 2.4- to 8.7-fold compared with the distilled water-sprayed control.
- Intervention effect Brassinolide upregulated hexokinase (HK) expression by 2.3- to 4.0-fold compared with the distilled water-sprayed control.
- Mechanism Brassinolide mitigates drought-induced silk growth arrest by orchestrating antioxidant defense, osmotic regulation and metabolic reprogramming.
