Phytosterols in tobacco leaves at various stages of physiological maturity
TLDR
Leaves of varying maturity from 84-day-old tobacco plants were harvested and analyzed for total sterol and their individual sterol components, and stimgasterol was principally responsible for this increase.About:

Effect of triadimefon and triadimenol on growth of various plant species as well as on gibberellin content and sterol metabolism in shoots of barley seedlings
Heinrich Buchenauer,E. Röhner +1 more
TL;DR: It is assumed that triadimefon and triadimenol interfere in gibberellin and sterol biosynthesis in barley seedlings by inhibiting oxidative demethylation reactions.

Biogenesis of steroids in solanaceae
TL;DR: The biogenetic pathways leading to the characteristic steroids of the Solanaceae are reviewed and their metabolism as well as biosynthesis are considered.

Steryl fatty acyl esters in plants
Lynne Dyas,L. John Goad +1 more
TL;DR: The recent advances in the analytical techniques for the identification and quantification of the individual intact steryl esters present in complex mixtures should now encourage and facilitate new investigations on these topics to clarify the nature and role of steryl Esters in plants.

Lipids and sterols of Pinus sylvestris L. sapwood and heartwood.
Pekka Saranpää,Harri Nyberg +1 more
TL;DR: In this paper, the lipid and sterol content and composition of three lipid fractions (free fatty acids/ sterols, triacylglycerols and sterols/triterpenoid esters) extracted from three stem discs of Pinus sylvestris were assessed to investigate metabolic changes related to heartwood formation.
Journal ArticleDOI
Characterization of Soybean Plasma Membrane during Development: FREE STEROL COMPOSITION AND CONCANAVALIN A BINDING STUDIES.
TL;DR: Electron microscope studies indicated that all root plasma membrane preparations were equivalent in terms of relative purity, and Hypocotyl membrane preparations contained significantly greater levels of contaminating membrane components.

Sterol Changes during Germination of Nicotiana tabacum Seeds
Parshall B. Bush,C. Grunwald +1 more
TL;DR: During germination, sitosterol was the major sterol in all fractions but stigmasterol and campesterol showed the greatest changes, and the fatty acid composition of the steryl esters and acylated steryl glycosides most closely resembled the di- and triglycerides.

Changes in the levels and composition of the esterified and unesterified sterols of maize seedlings during germination
R.J. Kemp,L.J. Goad,E.I. Mercer +2 more
TL;DR: During the germination period it was found that the level of “fast-reacting” sterol esters remains constant in all four morphological units and the composition of the shoot, scutellum and endosperm sterol mixtures does not change.
Journal ArticleDOI
Changes in Sterol Composition during Greening of Etiolated Barley Shoots
TL;DR: Etiolated barley seedlings exposed to light had a shift in the ratio of free stigmasterol to beta-sitosterol in favor of stig masterol; however, no correlation was observed between chlorophyll synthesis and shift in sterol composition.

Variations in sterol composition in etiolated mung bean seedlings
TL;DR: The sterol fractions of different morphological and physiological parts of etiolated Mung bean seedlings have been studied in this paper, showing that the sterol fraction of young growing tissues conta
