Plant hormones (or phytohormones) are signal molecules, produced within plants, that occur in extremely low concentrations. Plant hormones control all aspects of plant growth and development, including embryogenesis , [ 1 ] the regulation of organ size, pathogen defense, [ 2 ] [ 3 ] stress tolerance [ 4 ] [ 5 ] and reproductive development.

The Yang cycle. Ethylene is produced from essentially all parts of higher plants, including leaves, stems, roots, flowers, fruits, tubers, and seeds.
A phytoestrogen is a plant-derived xenoestrogen (a type of estrogen produced by organisms other than humans) not generated within the endocrine system, but consumed by eating plants or manufactured foods. [1]
Plant physiology is a subdiscipline of botany concerned with the functioning, or physiology, of plants. [1]A germination rate experiment. Plant physiologists study fundamental processes of plants, such as photosynthesis, respiration, plant nutrition, plant hormone functions, tropisms, nastic movements, photoperiodism, photomorphogenesis, circadian rhythms, environmental stress physiology, seed ...
Due to their mechanism of action, these molecules have been classified as plant hormones or phytohormones. [1] So far, strigolactones have been identified to be responsible for three different physiological processes: First, they promote the germination of parasitic organisms that grow in the host plant's roots, such as Striga lutea and other ...

Brassinosteroids, particularly the potent brassinolide, play a crucial role in controlling various plant processes such as germination, aging, and the ability to withstand environmental and biological stresses. [6]
