4-Chloroindole-3-acetic acid
Encyclopedia
4-Chloroindole-3-acetic acid (4-Cl-IAA) is a natural plant hormone
. It is a member of the class of compounds known as auxin
s and a chlorinated derivative of the more common auxin indole-3-acetic acid
(IAA). 4-Cl-IAA is found in the seeds of a variety of plants, particularly legumes such as peas and broad beans. It is hypothosized that 4-Cl-IAA may be a "death hormone" that maturing seeds use to trigger death of the parent plant by mobilizing nutrients to be stored in the seed.
Plant hormone
Plant hormones are chemicals that regulate plant growth, which, in the UK, are termed 'plant growth substances'. Plant hormones are signal molecules produced within the plant, and occur in extremely low concentrations. Hormones regulate cellular processes in targeted cells locally and, when moved...

Auxin
Auxins are a class of plant hormones with some morphogen-like characteristics. Auxins have a cardinal role in coordination of many growth and behavioral processes in the plant's life cycle and are essential for plant body development. Auxins and their role in plant growth were first described by...
