“…Ethylene has a detrimental effect on fruit tissue by stimulating activities of cell wall-degrading enzymes (Abeles and others 1992;Arshad and Frankenberger 2002). Aerobic respiration and the consequent free-radical generation play a role in the tissue-softening process.…”

The objective of this project was to treat fresh-cut apple slices with the ethylene inhibitor 1-methylcyclopropene (1-MCP) to retard ethylene-induced deterioration and senescence and to prolong the shelf life of such products. Intact Braeburn and Pacific Rose apples were treated at different times with 1-MCP, cut, and stored at 0 Њ Њ Њ Њ ЊC. Samples were analyzed initially and then weekly for ethylene, respiration, flesh firmness, tissue color, titratable acidity, and soluble solids content during 5 wk of storage. 1-MCP treatment was effective in reducing ethylene production, respiration, and loss of firmness and color of slices when applied to whole apples directly after harvest. Total sugar and acidity levels were not affected significantly.

“…Although the ACC N-malonyltransferase is developmentally regulated (Arshad and Frankenberger, 2002), the rate constant k 4 was considered invariant for the sake of simplicity. Both ACCs and ACCo are encoded by multigene families (Lelièvre et al, 1997) and are regulated by a number of regulating factors.…”

“…The respiration produces the ATP needed for the Yang cycle. Thanks to this recycling process, high levels of C 2 H 4 can be produced with a constant pool of Met (Arshad and Frankenberger, 2002). It is known that C 2 H 4 production rates in ripening fruit are controlled by the tissue's capability to synthesize ACC and to convert ACC to C 2 H 4 .…”

A theory of fruit climacteric ethylene emission was developed and used as the basis of a simulation model called ETHY. According to the theory, the biosynthetic pathway of ethylene is supplied by ATP and is regulated by 1-aminocyclopropane-1-carboxylic acid (ACC) synthase and ACC oxidase. The conjugation of ACC with malonate to form MACC was taken into account as a way to decrease the availability of ACC. Because of the seasonal increase of fruit volume, the dilution of biochemical compounds used in ETHY was taken into account. Finally, the ethylene diffusion across the skin was considered. The theory took into account the effect of temperature and O 2 and CO 2 internal concentrations on ethylene. The model was applied to peach (Prunus persica) fruit over 3 years, several leaf:fruit ratios, and irrigation conditions. An adequate ethylene increase was predicted without considering any increase in respiration during the ripening period, which suggests that the respiratory climacteric may not be required for ripening. Another important result of this study is the high sensitivity of ETHY to the parameters involved in the calculation of ACC oxidase and ACC synthase activities, ATP production, and skin surface and permeability. ETHY was also highly sensitive to changes in fruit growth and temperature.The plant hormone ethylene (C 2 H 4 ) plays a major role in the ripening process of climacteric fruits. Ripening parameters such as flesh softening (Haji et al., 2003;Hiwasa et al., 2003), color change (Flores et al., 2001), and production of aromas depend strongly on C 2 H 4 production (Rupasinghe et al., 2000;Alexander and Grierson, 2002;Flores et al., 2002).C 2 H 4 production in plant tissues has been studied extensively (Arshad and Frankenberger, 2002). It proceeds via a biosynthetic pathway, which was first established in apple (Malus domestica) fruit by Adams and Yang (1977). This pathway proceeds from Met, through S-adenosylmethionine (SAM) and 1-aminocyclopropane-1-carboxylic acid (ACC) to C 2 H 4 . The pathway enables high rates of C 2 H 4 production without high intracellular concentrations of Met. This is achieved by recycling 5#-methylthioadenosine (MTA) to Met through the Yang cycle. The respiration produces the ATP needed for the Yang cycle. Thanks to this recycling process, high levels of C 2 H 4 can be produced with a constant pool of Met (Arshad and Frankenberger, 2002). It is known that C 2 H 4 production rates in ripening fruit are controlled by the tissue's capability to synthesize ACC and to convert ACC to C 2 H 4 . The two key controls are ACC synthase (ACCs) and ACC oxidase (ACCo; Tucker, 1993). The C 2 H 4 is diluted in fruit tissue and then diffused into the atmosphere. Thus, fruit volume and permeability of skin to gas are important biophysical traits of fruit to consider when analyzing C 2 H 4 emission (Ben-Yehoshua and Cameron, 1989).The aim of this work was to develop a theory of C 2 H 4 emission, based on a mathematical representation of the respiration process and C 2 H 4 pathway.
