  abstract = {{A}bscission of organs from the plant body can be both developmentally and environmentally regulated. {T}he course of the abscission process is strongly influenced by plant hormones, among them ethylene ({ET}). {H}ormones are coordinators of all changes that occur in the abscission zone ({AZ}), where the ultimate molecular and cellular processes that lead to organ detachment occur. {M}ost of the recent studies regarding abscission aimed to examine the regulation of central pathways and subsequent steps functioning in the {AZ}. {T}he focus of this chapter addresses {ET} involvement in the local transformations that occur within the {AZ}. {S}pecifically, {ET}-dependent gene expression and enzymatic activities that control the initiation and execution of abscission processes are required in the {AZ}, given that these cells respond preferentially to {ET} and some cells may undergo programmed cell death. {H}owever, to understand the role of {ET} in these processes, we also consider




the changes that take place in the to be detached organ, which can also be a source of abscission-inducing signals. {T}herefore, the contribution of {ET} to changes that take place in the organ that undergoes abscission processes is also highlighted. {F}urthermore, abscission involves {ET} signaling and requires the coordinated action of different phytohormones, e.g. auxins and abscisic acid. {T}hus, {ET} interactions with other signaling molecules is the focus of the last section. {A}lthough great progress has been made in recent years in the understanding of {ET} responsiveness during abscission events, many questions still have to be answered. {W}e believe that this chapter summarizes the body of knowledge about this phenomenon and can be a basis for researchers who are fascinated by abscission processes. {W}e also hope that it provides a useful basis for other scientists to consider the exploration of this extremely interesting scientific area and improve




our knowledge about organ separation.},
