AB We examine the current knowledge about the abscission of fleshy fruit,in particular with regards to the development and function of the abscission zone(AZ). While tomato is currently the main model species to elucidate the mechanismsof fleshy fruit abscission, most studies on tomato focus on the developmentand function of the pedicel AZ, which is involved in both flower and ripe fruitabscission. However, the localization of the AZ within the pedicel is not the mostcommon location of the AZ for fleshy fruit. Fleshy fruit can have one or moreAZ, which can be found in different locations within the inflorescence and fruitingstructure and fulfil different functions. In fact,most of the fleshy fruit species examinedthus far havemore than one AZ,which can be found at the boundary betweenthe fruit and pedicel (often referred to as the calyx AZ), within the pedicel as withtomato, at the juncture of the pedicel and peduncle or at the juncture betweenpeduncle and shoot/branch. In addition, the different AZs may be activated orfunction at different stages of development, under different environmental conditions,or have a completely different purpose, such as the abscission of fruitletsor mature fruit. Together, our current knowledge about AZs suggests that whilethere are similarities between different AZs in different locations or from differentspecies, not all AZs are created equal, which may be reflected in the underlyingmolecular mechanisms that control their development and function.
