Synthesized in response to shoot environmental, pest, or disease stress
Synthesized in senescent leavesThis article is about the leaf a plant organ. See Leaf (disambiguation) for other meanings. In botany, a leaf is an above-ground plant organ specialized for photosynthesis. For this purpose, a leaf is typically flat and thin, to expose the chloroplast con and flowers
Inhibiting effects of Ethylene on shoot growth (more specifically on stem elongation) reduced in the presence of lightLight is electromagnetic radiation with a wavelength that is visible to the eye, or in a more general sense, any electromagnetic radiation in the range from infrared to ultraviolet. The three basic dimensions of light (and of all electromagnetic radiation. Also Ethylene levels are decreased by light
Released in mature cellstained for keratin The cell is the structural and functional unit of all living organisms. Some organisms, such as bacteria, are unicellular, consisting of a single cell. Other organisms, such as humans, are multicellular, (humans have an estimated 100,0s when they do not have enough mineralMinerals are natural compounds formed through geological processes. The term "mineral" encompasses not only the material's chemical composition but also the mineral structures. Minerals range in composition from pure elements and simple salts to very comps and waterDrinking water This article focuses on water as we experience it every day. The water (molecule) article describes water from a scientific and technical perspective. Water is an abundant substance on Earth. It exists in many forms, such as sea, rain, and to support both themselves and any dependent cells
Released by all cells when they are experiencing conditions which would normally cause a mature shoot cell to produce Ethylene
2 Effects
Stimulates leaf and flower senescence
Induces leaf abscission mainly in older versus younger leaves.
Induces seed germination
Induces root hair growth – this increases the efficiency of water and mineral absorption
Stimulates Epinasty – leaf petiole grows out, leaf hangs down and curls into itself
Interference with Auxin transport (when hormone levels are increasing)
Directly or indirectly induces Auxin at high levels
(From Theory II of plant hormones) Inhibits the rate of metabolism of cells in the shoot (who are not already at their lowest metabolism rates) in response to an decrease in the levels minerals and/or water
