Effects of in vivo inhibitors of carotene biosynthesis on the synthesis of carotenes by a soluble tomato plastid enzyme system

Preferential inhibition of the lycopene ε-cyclase by the substituted triethylamine compound MPTA in higher plants

“…Data is inconclusive for photosynthetic tissues (Sandmann and Bramley, 1985) whilst in other, in vitro, studies CPTA or MPTA have had no effect on carotenoid biosynthesis (Bucholtz et al, 1977;Beyer et al, 1980). In the present study, MPTA resulted in a ca.…”
