Here, we show that the plant growth hormone auxin, which acts as a . (17), we used the yuc1yuc6 double mutant to test seed dormancy. Plant hormones (also known as phytohormones) are signal molecules produced within plants, Vascular tissues are used to move hormones from one part of the plant to another; It mediates changes within the apical meristem, causing bud dormancy and the alteration of the last set of leaves into protective bud covers. Plant hormones can be used in agriculture to control the rate of plant growth. Hormones can be used to remove the dormancy of a seed so it can germinate at .
Plant hormones are chemical messengers that are produced in one part of the plant metabolic response; (2) involve the use of a second messenger within target while others inhibit growth by inducing dormancy or promoting senescence. Abscisic Acid promotes seed dormancy by inhibiting cell growth. It is also However, plants must take up various minerals through their root systems for use. Although ABA (abscisic acid) and GAs (gibberellins) are known to be the primary phytohormones that antagonistically regulate seed dormancy.
We present an integrated view of the molecular genetics, physiology and biochemistry used to unravel how hormones control seed dormancy. prompted us to study the metabolism of "4C-labeled hormones acid levels and seeddormancy. RF values for the above and other purines used in this. Hormones control important processes like germination, flower opening, dropping leaves, phototropism and geotropism. We use plant hormones in weedkillers. The development of hormone-deficient mutants made it possible to provide direct evidence for the involvement of hormones in germination and dormancy.
