Cell wall remodeling in Arabidopsis stamen abscission zones: Temporal aspects of control inferred from transcriptional profiling.

ABSTRACT: Organ shedding requires cell separation within abscission zones (AZs). Functional genomic AZ studies have been limited by their small size and low incidence. Optimization of laser capture microdissection (LCM) for AZs and other specialized cell types in Arabidopsis1 allowed recent characterization of the floral stamen AZ transcriptome responding to a developmental shedding cue.2 Analyses focused on 551 AZ transcripts (AZ(551)) that were regulated at the highest statistical significance (p
