Blue light makes soybean plants grow shorter by changing the balance of hormones inside them. It reduces growth hormones and increases hormones that stop growth. This effect is stronger in some soybean types than others.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.
Systematic Reviews & Meta-Analyses
Max 100Randomized Controlled Trials
Max 90Cohort Studies
Max 72Case-Control Studies
Max 58Cross-Sectional Studies
Max 44Case Reports & Case Series
Max 30Expert Opinion & Narrative Reviews
Max 544 / 72
Evidence Score
Groups of people are followed over time to see who develops an outcome. Strong for identifying risk factors and associations, but cannot prove causation as firmly as RCTs.

Tesamorelin is a growth hormone-releasing hormone analog that stimulates the pituitary gland to produce endogenous growth hormone in a physiologically appropriate pattern, as opposed to exogenous growth hormone administration.
When soybean plants were exposed to blue light, their height dropped by about two-thirds compared to plants grown in the dark, with both tall and short varieties showing similar reductions.
Blue light made the levels of a key growth hormone (GA3) drop by about 14% in tall soybeans and 20% in short soybeans when grown in the dark versus under blue light.
Under blue light, the stress hormone salicylic acid increased by about 56% in tall soybeans and 41% in short soybeans compared to plants grown in the dark.
In tall soybeans, the balance between growth hormone GA3 and stress hormone JA strongly predicted plant height, while in short soybeans, GA3 and strigolactones were the key ratio for height.
