Nucleotide sequence of a cDNA for 1-aminocyclopropane-1-carboxylate synthase from melon fruits
Ethylene is a plant hormone that has an essential role in fruit ripening. ACC synthase (S-adenosyl-L-methionine methylethioadenosine-lyase, EC 4.4.1.14), which is encoded by a multigene family, plays a regulatory role in ethylene production. Several genes for ACC synthase have been isolated from tom...

Summary: | Ethylene is a plant hormone that has an essential role in fruit ripening. ACC synthase (S-adenosyl-L-methionine methylethioadenosine-lyase, EC 4.4.1.14), which is encoded by a multigene family, plays a regulatory role in ethylene production. Several genes for ACC synthase have been isolated from tomato, mung bean, winter squash and Arabidopsis. We isolated a cDNA (pMEACS1, 2097 bp) for ACC synthase from wounded mesocarp tissue from melon fruits (Cucumis melo L. cv AMS). Sequence analysis of this cDNA revealed the presence of an open reading frame of 493 amino acids. This polypeptide contained seven sequences that were conserved among other ACC synthases. RNA blot analysis showed that the level of mRNA for the gene increased in the mesocarp tissue of melon fruits after wounding and also during ripening. |
