Natural plant growth regulators (natural-PGRs) are endogenous or naturally derived chemical compounds—such as auxins, gibberellins, cytokinins, and brassinosteroids—that regulate key developmental processes in plants including germination, root formation, flowering, and fruit development. Understanding and manipulating these compounds allows researchers to improve crop yield, stress tolerance, and developmental timing without relying on synthetic chemicals. This field bridges fundamental plant physiology with practical agricultural applications, offering sustainable strategies for enhancing plant performance.

Researchers discovered that a naturally occurring compound called AMHA can act as a plant growth booster for cucumbers, working by improving root development, nutrient uptake, and photosynthesis simultaneously — offering a potential natural alternative to synthetic plant growth chemicals.
AMHA increased levels of two key plant hormones — one that controls energy balance (trehalose-6-phosphate) and one that drives root growth (indole-3-acetic acid), resulting in improved root architecture
Enhanced root development led to more efficient uptake of four critical nutrients: nitrogen, phosphorus, potassium, and iron
AMHA upregulated photosynthetic genes in shoot tissue, boosting the plant's ability to convert sunlight into energy
