auxin

 

[ หˆษ”หksษชn ]

Noun
Context #1 | Noun

plant hormone

Auxin is a class of plant hormones that play a crucial role in coordinating various growth and behavioral processes in the plant's life cycle. They are primarily involved in regulating cell elongation, root growth, and differentiation, as well as fruit development. Auxins are essential for the plant's response to light and gravity, a phenomenon known as phototropism and gravitropism, respectively. The most well-known naturally occurring auxin is indole-3-acetic acid (IAA). These hormones are produced in the apical meristem and transported to other parts of the plant, influencing growth and developmental patterns.

Synonyms

growth regulator, plant hormone.

Examples of usage

  • Auxin promotes the elongation of cells in the stem.
  • Plants use auxin to regulate their growth direction.
  • High concentrations of auxin can inhibit leaf abscission.
  • Exogenously applied auxins can enhance root formation in cuttings.

Etymology

The term 'auxin' originates from the Greek word 'auxein', which means 'to grow' or 'to increase'. The concept of auxins and their role in plant growth was first introduced in the early 20th century as scientists began to explore plant physiology. In the 1920s, researchers identified the first plant growth substances, and the term auxin was coined to describe these hormones that promote growth and cell elongation. Over the decades, various types of auxins have been discovered, with indole-3-acetic acid (IAA) being the most studied and recognized in nature. The understanding of auxins has expanded, revealing their complex roles in plant development, including responses to environmental stimuli, such as light and gravity, further highlighting the sophistication of plant regulatory mechanisms.
