TL;DR: In this paper, a cold treatment is followed by an ethylene treatment, and a more rapid softening occurs than in apples that have not had a previous cold treatment, indicating that either these two pathways act independently and synergistically with each other or cold enhances the response such that background levels of ethylene in the ethylene-suppressed apples are sufficient to induce fruit softening.

TL;DR: It is shown that in cv Royal Gala apples that have the ethylene biosynthetic gene ACC OXIDASE1 suppressed, a cold treatment preconditions the apples to soften independently of added ethylene, suggesting a possible molecular mechanism for the cold- and ethylene-regulated control of fruit softening.
