Interpretive Summary: Abscission, also known as organ separation, is a plant cell separation event that occurs in a finite layer of cells at the base of an organ, e.g. leaf, flower, fruit, petals, etc. We have reviewed and summarized 21 articles published under the special topic of abscission published in Frontiers in Plant Science. The information and technologies published in this collection of articles will be used by researchers in the government, private industry and universities who want to understand and to improve leaf, flower and fruit drop in many horticultural and crop species like tomatoes, apples, and soybeans.

Technical Abstract: The shedding of plant organs is a highly coordinated process essential for both vegetative and reproductive development (Addicott, 1982; Sexton and Roberts, 1982; Roberts et al., 2002; Leslie et al., 2007; Roberts and Gonzalez-Carranza, 2007; Estornell et al., 2013). Research with model plants, namely floral organ abscission in Arabidopsis and leaf, flower and fruit abscission of tomato, and seed shattering in rice has provided new insights in to the molecular mechanisms underlying abscission. However, little is known about how these mechanisms that take place in the abscission zone (AZ) have diversified during plant evolution and differ between species and plant families, and within diverse tissues and developmental contexts. A major aim of this topic was to examine diverse organ abscission examples from a wide range of species in order to provide a format for comparisons between model and important crop species.
