Inflorescence abscission protein SlIDL6 promotes low light intensityinduced tomato flower abscission [PDF]

, 2021
In many fruiting plant species, flower abscission is induced by low light stress. Here, we elucidated how signaling mediated by the peptide INFLORESCENCE DEFICIENT IN ABSCISSION (IDA) controls low light-induced flower drop in tomato (Solanum lycopersicum)

Jasmonic Acid Activates the Fruit-Pedicel Abscission Zone of ‘Thompson Seedless’ Grapes, Especially with Co-Application of 1-Aminocyclopropane-1-carboxylic Acid

Plants, 2022
Two studies were conducted to determine how methyl jasmonate (MeJA), jasmonic acid (JA), and 1-aminocyclopropane-1-carboxylic acid (ACC) affect grape berry abscission in the initial days after treatment.

Bracing for Abscission [PDF]

Cell, 2018
The detachment of plant organs is highly choreographed, requiring the enzymatic dissolution of the middle lamella between cell layers at the base of the detaching organ. Now, Lee et al. demonstrate that abscission efficiency and plant health rely on the spatial confinement of enzymatic activity and mechanical features that ensure a smooth separation.

A family of auxin conjugate hydrolases from Solanum lycopersicum and analysis of their roles in flower pedicel abscission

BMC Plant Biology, 2019
Background Auxin conjugates are hydrolyzed to release free auxin to ensure defined cellular auxin levels or gradients within tissues for proper development or response to environmental signals.

The transcription factor MebHLH18 in cassava functions in decreasing low temperature-induced leaf abscission to promote low-temperature tolerance

Frontiers in Plant Science, 2023
The reactive oxygen species (ROS) signal regulates stress-induced leaf abscission in cassava. The relationship between the function of the cassava transcription factor bHLH gene and low temperature-induced leaf abscission is still unclear.

Cold stress triggers premature fruit abscission through ABA-dependent signal transduction in early developing apple.

PLoS ONE, 2021
Fruit abscission is a complex physiological process that is regulated by internal and environmental factors. During early development, apple fruit are exposed to extreme temperature fluctuations that are associated with premature fruit drop; however ...

The Promotion of Abscission by Auxin [PDF]

Plant Physiology, 1955
Though some scientific studies on the abscission of plant organs had started as early as 1860 (10), the role of the growth hormone in this process was first suggested by the work of Laibach in 1933 (6). He observed that orchid pollinia inserted in the split ends of petioles of debladed Coleus delayed abscission 11 to 20 days beyond that of untreated ...

Auxin is a long-range signal that acts independently of ethylene signaling on leaf abscission in Populus

Frontiers in Plant Science, 2015
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 ...

Abscission: The Role of Aging [PDF]

Plant Physiology, 1967
Excision of Phaseolus vulgaris L. c.v. Red Kidney abscission zone explants results in senescence, mobilization, and abscission. Because these processes take place at about the same time, there has been some question as to whether they are causally related or are occurring in an independent but simultaneous fashion.
