This video explores the fascinating world of plant hormones, also known as plant growth regulators.
1. Key Differences: Learn how plant hormones differ from animal hormones in terms of production and target areas.
2. Major Classes of Plant Hormones: Discover the five major classes of plant hormones: auxins, cytokinins, abscisic acid (ABA), gibberellins, and ethylene.
Plant hormones differ from animal hormones in that:
1. Plant hormones are not made in tissues specialized for hormone production. (e.g., sex hormones made in the gonads, human growth hormone - pituitary gland)
2. Unlike animal hormones, plant hormones do not have definite target areas (e.g., auxins can stimulate adventitious root development in a cut shoot, or shoot elongation or apical dominance, or differentiation of vascular tissue, etc.).
General Plant Growth Regulators (PGRs)
Auxin: Indole compounds (indole-3-aceticacid, IAA)
Cytokinin: Adenine derivatives (N6-furfurylamino purine, kinetin),
ABA: Derivatives of carotenoids (abscisic acid)
Gibberellins: Terpenes (gibberellic acid, GA3)
Gases (Ethylene, C2H4).
This video is a valuable resource for students, researchers, and anyone interested in plant biology and the mechanisms that regulate plant growth and development.
