Inhibition by plant growth retardants of cholesterol biosynthesis in slices of rat liver and hepatoma.
The plant growth retardant Phosfon inhibits cholesterol formation by cell·free preparations of normal liver and the Morris hepatomas 5123C, 7794A, and 9618A. In addition, both Phosfon and Amo 1618 arc active in inhibiting cholesterol synthesis from acetate and mevalonate in slices of host liver and the hepatomas. Fatty acid synthesis from acetate was also reduced in the presence of the retardants.

15 صفحه اولInhibition of Gibberellin Production in the Fungi Gibberella fujikuroi and Sphaceloma manihoticola by Plant Growth Retardants.
The effect of different types of plant growth retardants on fungal gibberellin (GA) formation has been studied in cultures of Gibberella fujikuroi and Sphaceloma manihoticola. Quaternary ammonium compounds (chlormequat chloride, mepiquat chloride, Amo-1618), triazoles (uniconazole and several experimental compounds), and the norbornanodiazetine tetcyclacis inhibited GA biosynthesis in both fung...
متن کاملLipid transformations in greening and senescing leaf tissue.
Analyses were made of chlorophyll a and b and fatty acids (18:3, 18:2, 18:1, 18:0, 16:2, 16:1, and 16:0) of greening and senescing leaf tissue. Those dark-grown tissues given a prior treatment of red, far red, or red followed by far red light showed similar increases in chlorophylls and linolenate (18:3) when exposed to continuous white light. In contrast, green barley (Hordeum vulgare L.) leav...
