The lipoxygenase pathway in tulip (Tulipa gesneriana): detection of the ketol route.
The in vitro metabolism of [1-(14)C]linoleate, [1-(14)C]linolenate and their 9(S)-hydroperoxides was studied in cell-free preparations from tulip (Tulipa gesneriana) bulbs, leaves and flowers. Linoleate and its 9-hydroperoxide were converted by bulb and leaf preparations into three ketols: (12Z)-9-hydroxy-10-oxo-12-octadecadienoic acid (alpha-ketol), (11E)-10-oxo-13-hydroxy-11-octadecadienoic a...
متن کاملLow temperature sensing in tulip (Tulipa gesneriana L.) is mediated through an increased response to auxin.
Tulip (Tulipa gesneriana L.) is a bulbous plant species that requires a period of low temperature for proper growth and flowering. The mechanism of sensing the low temperature period is unknown. The study presented in this paper shows that the essential developmental change in tulip bulbs during cold treatment is an increase in sensitivity to the phytohormone auxin. This is demonstrated using a...

15 صفحه اولLipoxygenase pathway in tulip: biosynthesis of ketols.
The metabolism in vitro of [1-(14)C]linoleate, [1-(14)C]linolenate and their 9(S)-hydroperoxides in tulip (Tulipa gesneriana) was found to be under the control of 9-lipoxygenase and allene oxide synthase, and directed towards alpha-ketol, gamma-ketol and the novel compound (12Z)-10-oxo-11-hydroxy-12-octadecadienoic acid (10,11-ketol). Potent activity of allene oxide cyclase (in bulbs) and a new...
