Gibberellinide

Gibberellinide refers to a class of plant hormones known as gibberellins (GAs). These are diterpenoid compounds that play a crucial role in plant growth and development. The term "gibberellinide" is often used interchangeably with gibberellin itself, highlighting their fundamental function in regulating various physiological processes. Key functions attributed to gibberellins include the promotion of stem elongation, seed germination, and flowering. They also influence fruit development and can help overcome dormancy in seeds and buds.

Gibberellins are synthesized in young leaves, developing seeds, and roots. They act by binding to specific receptor proteins within plant cells, triggering a cascade of molecular events that ultimately lead to altered gene expression. This hormonal signaling pathway is essential for plants to respond to environmental cues and optimize their growth patterns. The discovery of gibberellins originated from observations of a disease affecting rice plants caused by the fungus Gibberella fujikuroi, which led to excessive stem elongation. Subsequent research identified the active compounds responsible for this effect. Understanding gibberellinide action is vital for agricultural applications, as manipulating these hormones can be used to enhance crop yields and control plant architecture.
