A gas molecule plants produce called nitric oxide acts as a brake on growth by interfering with brassinosteroids, the hormones that tell plants to grow bigger. Plants with too little nitric oxide grow faster and respond more strongly to growth hormones, while plants with too much show developmental problems.
1
Seedlings lacking nitric oxide show enhanced growth and hyper-respond to brassinosteroid treatments compared to normal plants.
2
Plants with activated brassinosteroid signaling accumulate excess nitric oxide, suggesting a negative feedback loop between the hormone and the gas.
3
Nitric oxide-deficient plants had elevated levels of brassinolide, the most biologically active brassinosteroid, which likely explains their faster growth.
