Abstract
Chorismate mutase (CM, EC 5.4.99.5), phenylalanine ammonia-lyase (PAL, EC 4.3.1.5) and chalcone synthase (CHS, EC 2.3.1.74) activities were studied in constitutive salicylic acid-producing (CSA) tobacco plants in relation to the accumulation of flavonoids and chlorogenic acid. The CM, PAL and CHS activities in CSA-tobacco (Nicotiana tabacum cv. Samsun NN) plants were lower than in non-transgenic tobacco plants. Flavonoid and chlorogenic acid accumulation was suppressed in CSA-tobacco plants compared to those of non-transgenic tobacco plants.
