Growth and productivity of higher plants are adversely affected by various environmental stresses, which are of two main types, biotic and abiotic.
Broad range of abiotic stresses includes osmotic stress caused by drought, salinity, high or low temperatures, freezing, or flooding, as well as ionic, nutrient, or metal stresses, and others caused by mechanical factors, light, or radiation.
All kinds of abiotic stress factors are probably the most limiting for crop quality and productivity, comprising economic output and human food supply.
Plants have developed some physiological, biochemical, or molecular mechanisms to overcome effects of stress. Plant hormones, such as Abscisic acid, Jasmonic Acid, Ethylene, and Salicylic Acid, mediate various abiotic and biotic stress responses.

1. Growth regulators: Auxins, Brassinosteroids, Cytokinins, Ethylene releasers. Besides their regulatory functions during development, they play key roles and coordinate various signal transduction pathways during responses to environmental stresses.
2. Amino acids derivatives from cysteine and methionine. The many effects include osmoregulation, enzyme activity by co-factors, interaction with symbionts, plant hormone synthesis and signalling.
Sulfur serves important structural, regulatory, and catalytic functions in the context of proteins and as a cellular redox buffer in the form of tripeptide glutathione and certain proteins such as thioredoxin, glutaredoxin, and protein disulfide.
Cysteine is the essential precursor of all organic molecules containing reduced sulfur; these range from the amino acid methionine to peptides such as glutathione, or phytochelatins, protein, vitamins, cofactors such as S-adenosyl methionine (SAM), and hormones.
Cysteine and derived metabolites have the ability to regulate and repair abiotic stress-induced reactive oxygen species.
