In a previous report, we discussed mechanisms that regulate expression of the gene for a wound-inducible 1-aminocyclo-propane-1- carboxylate synthase (CM-ACS1, formerly called WSACS2) in disks of mesocarp tissue from winter squash (Cucurbita maxima) fruit. Recently, we isolated two new cDNA fragments (whose products are designated CM-ACS3 and CM-ACS4) that encode ACC synthases from the same material by the reverse transcriptase-polymerase chain reaction using the same conditions as those used for cloning the gene for CM-ACS1. We also isolated full-length cDNAs that encoded CM-ACS3 and CM-ACS4. The accumulation of specific transcripts for CM-ACS1, CM-ACS3 and CM-ACS4 in the tissue disks was induced by mechanical wounding. Treatment with jasmonic acid (JA) affected the accumulation of the three transcripts differently. JA stimulated the accumulation of the CM-ACS1 transcript; it had no effect on the accumulation of the CM-ACS3 transcript; and it suppressed the accumulation of the CM-ACS4 transcript to some extent. Accumulation of the CM-ACS1 transcript was suppressed by treatment with ethylene; accumulation of the CM-ACS3 transcript was stimulated by ethylene; and ethylene had no effect on the accumulation of the CM-ACS4 transcript.
