Abscission of flowers and floral organs is closely associated with alkalization of the cytosol in abscission zone cells [PDF]
Journal of Experimental Botany, 2014 In vivo changes in the cytosolic pH of abscission zone (AZ) cells were visualized using confocal microscopic detection of the fluorescent pH-sensitive and intracellularly trapped dye, 2',7'-bis-(2-carboxyethyl)-5(and-6)-carboxyfluorescein (BCECF), driven by its acetoxymethyl ester.

Involvement of IDA-HAE Module in Natural Development of Tomato Flower Abscission
Plants, 2023 The unwanted detachment of organs such as flowers, leaves, and fruits from the main body of a plant (abscission) has significant effects on agricultural practice.

Regulation of floral organ abscission in Arabidopsis thaliana [PDF]
Proceedings of the National Academy of Sciences, 2008 Abscission is a developmental program that results in the active shedding of infected or nonfunctional organs from a plant body. Here, we establish a signaling pathway that controls abscission in Arabidopsis thaliana from ligand, to receptors, to downstream effectors.

Integrative analysis of transcriptome, proteome, and ubiquitome changes during rose petal abscission
Frontiers in Plant Science, 2022 Plant organ abscission is regulated by multiple physiological and biochemical processes. However, the transcriptional, translational, and post-translational modifications occurring during organ abscission have not been systematically investigated.

Genome-wide analysis of AP2/ERF gene family in Camellia oleifera and its potential roles in ethylene-induced fruit abscission. [PDF]
BMC Plant BiolBackground Camellia oleifera is a commercially important woody edible oil tree species in China. Yet, heavy premature fruit drop causes substantial yield losses and significantly limits the economic potential of the oil tea industry.

Expression Divergence and Functional Redundancy of Polygalacturonases in Floral Organ Abscission [PDF]
Plant Signaling & Behavior, 2006 The importance of cell separation in plant development cannot be overemphasized. The polygalacturonases (PGs) are the one of cell wall hydrolytic enzyme families that has been associated with various cell separation processes in plant development including seed germination, dehiscence, organ abscission, and fruit ripening.

INFLORESCENCE DEFICIENT IN ABSCISSION Controls Floral Organ Abscission in Arabidopsis and Identifies a Novel Family of Putative Ligands in Plants [PDF]
THE PLANT CELL ONLINE, 2003 Abscission is an active process that enables plants to shed unwanted organs. Because the purpose of the flower is to facilitate pollination, it often is abscised after fertilization. We have identified an Arabidopsis ethylene-sensitive mutant, inflorescence deficient in abscission (ida), in which floral organs remain attached to the plant body after ...

Transcriptome analysis of tomato flower pedicel tissues reveals abscission zone-specific modulation of key meristem activity genes. [PDF]
PLoS ONE, 2013 Tomato flower abscises at the anatomically distinct abscission zone that separates the pedicel into basal and apical portions. During abscission, cell separation occurs only at the abscission zone indicating distinctive molecular regulation in its cells.
