ETHY. A Theory of Fruit Climacteric Ethylene Emission

Abstract: 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 t… Show more

“…Na temperatura de 0,5 °C, menores concentrações de O 2 (0,8 kPa) reduziram a atividade desta enzima. A atividade da enzima ACC oxidase é diretamente influenciada pela presença de O 2 (GÉNARD; GOUBLE, 2005). Já na temperatura de 1 °C, a maioria das condições de AC foram eficientes para reduzir a atividade da ACC oxidase, exceto a condição com 1,2 kPa O 2 mais 2,0 kPa CO 2 .…”

“…However, more has to be learned about the retention and release of ethylene in plant tissues in relation to its resistance towards the diffusion across the boundaries of fruit and physiological activity of ethylene bound to its receptor (Ben-Yehoshua et al 1985;Goldschmidt et al 1993). So, to get better understanding of ethylene emission by tomato fruit Genard and Gouble (2005) developed a simulation model called 'ETHY'. Two systems of ethylene production have been defined in plants (McMurchie et al 1972).…”

“…In this regard, as already stated, a theory of ethylene emission was developed and used as the base to develop simulation model called "ETHY" by Genard and Gouble (2005). This model was found to be highly sensitive to the factors such as permeability of the fruit skin, internal concentration of O 2, CO 2 and ACC, changes in fruit growth and temperature, activities of ACCoxidase and ACC-synthase, concentration of ethylene itself and production status of ATP.…”

In this direction, a theory of ethylene emission by tomato fruit was developed and used as a base to develop simulation model called 'ETHY' by Genard and Gouble (2005). This model was found to be highly sensitive to the parameters like; permeability of skin surface, internal concentration of O 2 , CO 2 and ACC, change in fruit growth and temperature, activities of ACC-oxidase and ACC-synthase, concentration of ethylene itself and ATP production status.…”
