Plant growth regulators are hormones, elicitors and synthetic compounds that control plant development. Gibberellin A7 belongs to the gibberellins, diterpenoid hormones that promote stem elongation and seed germination. (22S,23S)-Homobrassinolide is a brassinosteroid, one of the steroid hormones that regulate cell expansion. Coronatine, a phytotoxin of the bacterium Pseudomonas syringae, mimics the active jasmonate hormone jasmonoyl-isoleucine. Syringolin A, produced by the same species, is a proteasome inhibitor that acts as an elicitor of plant defense responses. Antabactin antagonizes abscisic acid (ABA) receptors, and Germination-IN-2 is listed as a seed germination inhibitor. Synthetic regulators include cloxyfonac, a phenoxyacetic acid derivative with auxin-type activity in plant tissues.
Germination-IN-2 is a potent germination inhibitor that targets seed germination processes. Demonstrating an IC50 of 1.3 µM, it effectively restricts germination, resulting in an observed germination rate of only 3%. This compound is suitable for research applications focused on seed biology, plant growth regulation, and agricultural studies.
Brassinazole is a selective triazole-type inhibitor of brassinosteroid (BR) biosynthesis. It effectively disrupts the BR pathway, thereby influencing plant growth and development. This compound is utilized in various research applications to study the physiological roles of brassinosteroids and their impact on plant hormone signaling.
(Rac)-Brassinazole is a triazole-type compound that functions as a brassinosteroid biosynthesis inhibitor. It effectively inhibits the CYP90B enzyme, which plays a crucial role in the synthesis of brassinosteroids. This compound is valuable for research applications investigating the regulation of plant growth and development mediated by brassinosteroids.
2-Methoxy-4-vinylphenol is a potent germination inhibitor that functions to suppress the growth of plant seeds by interfering with the germination process. Its primary biological activity includes the modulation of inflammatory responses, making it a valuable tool for research into plant biology and agriculture. This compound is applicable in studies focused on seed dormancy, germination regulation, and the exploration of plant defense mechanisms.
F1874-108 is a potent inhibitor of brassinosteroid biosynthesis and signal transduction. This compound effectively disrupts the brassinosteroid pathway, leading to inhibition of plant growth and development. It is utilized in research to study the role of brassinosteroids in plant physiology and their impact on growth regulation.

Its mechanism of action makes it a valuable tool for studying plant growth regulation and herbicide interactions in botanical research.
Synonyms: 7-Methoxy-NAA
7-Methyl-1-naphthyl acetic acid is a potent auxin transport inhibitor that specifically targets AUX1, PIN, and ABCB protein-mediated auxin transport. This compound effectively disrupts auxin signal transduction pathways, making it valuable for research in plant development and growth regulation. It is particularly useful in studies exploring the role of auxin in processes such as cell elongation, patterning, and tropisms.
Germination-IN-1 is a potent germination inhibitor targeting seed germination processes, with an IC50 of 4 µM. This compound effectively reduces germination rates, demonstrating a notable 14% germination activity in assays. It serves as a valuable tool for research in plant biology and agricultural studies, facilitating investigations into the regulation of germination and seed dormancy.
Uniconazole-P is a plant growth retardant that functions as a gibberellin biosynthesis inhibitor. It effectively promotes flower bud formation in various woody plants and can alter the sex expression of cucumbers, favoring female flower development. This compound is valuable in agricultural and horticultural research, particularly for studies aimed at optimizing plant growth and reproductive strategies.
Synonyms: Alanap 1
N-1-Naphthylphthalamic acid is a selective inhibitor of auxin transport, functioning by competing with indole-3-acetic acid (IAA) for membrane binding sites. This compound plays a crucial role in studies of auxin-related processes, as it disrupts maize leaf initiation, regulates KNOX proteins, and influences leaf margin formation. Its unique mechanism makes it valuable for research in plant developmental biology and auxin signaling pathways.
