Abstract:

Exposure to an atmosphere of 30% carbon dioxide caused increased levels of phenylalanine ammonia-lyase (PAL) activity in avocado cell suspension cultures. The carbon dioxide treatment also enhanced chalcone synthase activity by 30% and resulted in a 1.5-2 fold greater accumulation of epicatechin than in untreated cells. It was concluded that the level of epicatechin in avocado suspension cells can be increased by carbon dioxide, and this increase appears to be regulated by PAL and CHS activation.
