Abeles F B & Rubinstein B. Regulation of ethylene evolution and leaf abscission by auxin. Plant Physiol 39:963-9, 1964

چکیده
The authors found that auxin stimulated ethylene production, and that it was the gas which promoted abscission after the ability of auxin to delay aging was lost. This paper provided experimental proof for the principle that ethylene could act as a second messenger in some of the effects of auxin on plant growth and development.

متن کاملAuxin is a long-range signal that acts independently of ethylene signaling on leaf abscission in Populus
Timing of leaf abscission is an important trait for biomass production and seasonal acclimation in deciduous trees. The signaling leading to organ separation, from the external cue (decreasing photoperiod) to ethylene-regulated hydrolysis of the middle lamellae in the abscission zone, is only poorly understood. Data from annual species indicate that the formation of an auxin gradient spanning t...
متن کاملAbscission: the initial effect of ethylene is in the leaf blade.
The leaf blade of cotton (Gossypium hirsutum L. cv. Stoneville 213) was investigated as the initial site of ethylene action in abscission. Ethylene applied at 14 mul/l to intact 3-week-old plants caused abscission of the third true leaf within 3 days. However, keeping only the leaf blade of this leaf in air during ethylene treatment of the rest of the plant completely prevented its abscission f...
متن کاملAbscission: support for a role of ethylene modification of auxin transport.
Three types of whole plant experiments are presented to substantiate the concept that an important function of ethylene in abscission is to reduce the transport of auxin from the leaf to the abscission zone. (a) The inhibitory effect of ethylene on auxin transport, like ethylene-stimulated abscission, persists only as long as the gas is continuously present. Cotton (Gossypium hirsutum L. cv. St...
