Gibberellin signaling is a crucial plant hormone pathway that regulates various aspects of growth and development, including seed germination, stem elongation, and flowering. This signaling involves the perception of gibberellins by receptors, leading to the degradation of DELLA proteins, which are growth repressors, thereby promoting plant growth processes.

Gibberellin Signaling

Plant hormone pathway

Growth and development refer to the processes by which organisms increase in size and complexity over time, encompassing both physical and cognitive changes. While growth typically involves quantitative changes like height and weight, development includes qualitative transformations such as emotional maturity and skill acquisition.

Growth And Development

Seed germination is the process by which a seed develops into a new plant, involving a series of physiological and biochemical changes triggered by environmental conditions such as water, temperature, and light. Successful germination requires the breaking of seed dormancy, activation of metabolic pathways, and the emergence of the radicle as the first sign of growth.

Seed Germination

Stem elongation is a critical growth process in plants, primarily driven by the plant hormone gibberellin, which allows stems to grow longer and reach for light. This process is influenced by environmental factors such as light quality and quantity, temperature, and nutrient availability, making it essential for plant adaptation and survival.

Stem Elongation

Flowering is a crucial phase in the life cycle of angiosperms, where the plant transitions from vegetative growth to reproductive development, resulting in the production of flowers. This process is regulated by a complex interplay of genetic, hormonal, and environmental signals that ensure successful pollination and seed formation.

Flowering

Perception of gibberellins

Receptors are specialized protein molecules located on the surface of cells or within cells that bind to specific ligands, triggering a biological response. They play a crucial role in cellular communication, influencing numerous physiological processes and are essential targets in drug development.
