STRIGOLACTONE Meaning and
Definition
-
Strigolactones are a class of naturally occurring plant hormones that regulate various physiological processes within plants. They are a group of chemical compounds that act as signaling molecules in plant growth and development. They were initially discovered for their role in promoting the germination of parasitic plants called striga, which attack the roots of important crop plants, causing significant yield losses.
The structure of strigolactones consists of a butenolide core with varying side chains. These side chains contribute to the diversity of strigolactone compounds found in different plants. Strigolactones are mainly produced in the plant's roots, from where they are transported to other parts of the plant. Their production is regulated by an array of environmental cues, including light, nutrient availability, and plant-microbe interactions.
Strigolactones play critical roles in many aspects of plant growth and development, such as root architecture, shoot branching, and seed germination. They inhibit excessive shoot branching (tillering), promoting the allocation of resources to the main stem. Strigolactones also regulate root growth, including lateral root formation and root hair development, which are essential for nutrient acquisition and interaction with beneficial soil microorganisms.
Beyond their role in plant development, strigolactones have been shown to function as a signaling molecule in plant-microbe interactions, attracting beneficial mycorrhizal fungi to the plant's root system. They also play a role in regulating plant responses to various environmental stresses, such as drought and nutrient deficiency.
The discovery and understanding of strigolactones have not only provided insights into fundamental plant physiology but also have significant implications for agriculture, particularly in improving crop yield and managing parasitic weeds.

Etymology of STRIGOLACTONE
The word "strigolactone" is derived from "strigol", which comes from the Latin term "striga" meaning "witch" or "hag". Striga is also the name for a parasitic plant genus known for its weed-like qualities. The suffix "lactone" refers to a specific type of organic compound that includes a cyclic ester group. Thus, "strigolactone" is a compound that was named after its resemblance to the natural compounds found in the Striga genus, possessing similar chemical characteristics.
