ABSCISSINS Meaning and
Definition
-
Abscissins refers to a group of plant hormones known as carotenoids that regulate various growth and developmental processes in plants. These hormones play a crucial role in the control of leaf senescence, abscission (the natural shedding or dropping of leaves, flowers, or fruits), and dormancy.
Abscissins are primarily synthesized in the chloroplasts of leaves, where they accumulate before being translocated to the abscission zone, which is the specific region where leaves or other plant parts are shed. These hormones act by binding to specific receptors on the cells of the abscission zone, triggering a series of biochemical reactions that ultimately lead to the weakening and eventual separation of the abscised part.
One important function of abscissins is to regulate the timing and pattern of leaf senescence, ensuring that nutrients are optimally relocated within the plant during different stages of growth. Additionally, abscissins are involved in the regulation of dormancy in certain plant organs, such as buds and seeds. They play a crucial role in the induction, maintenance, and breaking of dormancy, enabling plants to undergo growth and development under favorable conditions.
Overall, abscissins act as important signal molecules in plants, allowing them to respond and adapt to environmental cues and optimize their growth and reproductive strategies.
