Question
Write the differences between Auxins and Gibberellins.
Answer
| Auxins | Gibberellins |
|---|---|
| Indole-3-acetic acid (IAA) is the primary auxin found in plants | Gibberellins are diterpenoid compounds synthesized from isopentenyl pyrophosphate |
| Produced primarily in the shoot apical meristem and young leaves | Produced in the shoot and root apical meristems, young leaves, and developing seeds |
| Promote cell elongation, regulate apical dominance, stimulate root initiation, and play a role in tropisms and fruit development | Promote stem elongation and cell division, stimulate seed germination and dormancy breaking, regulate flower development and sex determination, and enhance tolerance to environmental stressors |
| Act by binding to specific receptors on the surface of plant cells and triggering a signal transduction pathway | Bind to specific receptors and regulate gene expression and cellular responses |
| Examples – Indole-3-acetic acid (IAA), 2,4-dichloro phenoxy acetic acid (2,4-D) | Examples – Gibberellic acid (GA), gibberellin A3 (G |
