Role of ethylene in the biosynthetic pathway of aliphatic ester aroma volatiles in Charentais Cantaloupe melons.

Compared to other melon types, Cantaloupe Charentais melons are highly aromatic with a major contribution to the aroma being made by aliphatic and branched esters. Using a transgenic line in which the synthesis of the plant hormone ethylene has been considerably lowered by antisense ACC oxidase mRNA (AS), the aliphatic ester pathway steps at which ethylene exerts its regulatory role were found....

Climacteric fruit ripening: Ethylene-dependent and independent regulation of ripening pathways in melon fruit

Cantaloupe melons have a typical climacteric behaviour with ethylene playing a major role in the regulation of the ripening process and affecting the ripening rate. Crossing of Cantaloupe Charentais melon with a non-climacteric melon indicated that the climacteric character is genetically dominant and conferred by two duplicated loci only. However, other experiments made by crossing two non-cli...

Pyrazinamide and derivatives block ethylene biosynthesis by inhibiting ACC oxidase

Ethylene is an important phytohormone that promotes the ripening of fruits and senescence of flowers thereby reducing their shelf lives. Specific ethylene biosynthesis inhibitors would help to decrease postharvest loss. Here, we identify pyrazinamide (PZA), a clinical drug used to treat tuberculosis, as an inhibitor of ethylene biosynthesis in Arabidopsis thaliana, using a chemical genetics app...

Antisense ACC Oxidase RNA Delays Carnation Petal Senescence

The phytohormone ethylene is essential for senescence in many fruits and flowers. In the biosynthesis of ethylene in plants, the conversion of S-adenosyl methionine (SAM) to 1-aminocyclopropane1-carboxylic acid (ACC) and the conversion of ACC to ethylene are catalyzed by ACC synthase (ACS) and ACC oxidase (ACO), respectively (Adams and Yang, 1979). Using a cDNA clone representing carnation ACO ...

Inhibition of Ethylene Production and Acc Oxidase Activity in Avocado by Acetaldehyde Vapours

Exogenous application of acetaldehyde (AA) vapour (5000 ppm for 18 h) to peeled avocado fruits prior to storage caused inhibition of fruit ripening. This inhibition was characterized by a delay in fruit softening and reduction in ethylene production. Moreover, addition of 1aminocyclopropane-l-carboxylic acid (ACC), the precursor of ethylene, to avocado disks (in situ) or to avocado extract (in ...
