et al., 2012 , 2014 ). Owing to its longevity, stability, and ability to cross biological membranes, H 2 O 2 is the most ubiquitous intracellular messenger ( Rhee et al., 2017 ). H 2 O 2 oxidizes cysteine thiol groups of phosphatases, which are

). Extensive study on oxidative stress has demonstrated that exposure of plants to low temperature always induces the overproduction of reactive oxygen species (ROS), such as superoxide radical (O 2 ·− ), H 2 O 2 , and hydroxyl radical (HO · ) in plant cells

; Pavoncello et al., 2001 ), but Ca 2+ made the heat treatment even more efficacious ( Klein et al., 1997 ; Sams et al., 1993 ). Signaling pathways involving Ca 2+ include the production of reactive oxygen species, such as H 2 O 2 , that activate defense

mechanisms also operate in CMNP-mediated abscission process. We showed that other signaling molecules are reactive oxygen species (ROS), such as O ·− , H 2 O 2 , and hydroxyl radicals (OH · ), in CMNP-mediated abscission cascade ( Kumar and Ebel, 2015
