Low 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...
متن کاملTemperature Regulation of Endogenous Gibberellin Activity and Development of Tulipa gesneriana L.
The changes in the contents of free and bound gibberellin-like activity (GA) of Tulipa gesneriana L. cv. Ralph during development under 2 temperature conditions were studied. The results show that the content of free GA of bulbs grown at 18 degrees increased by 67% over the initial level during development. The bound GA showed a slight initial increase and was followed by a rapid decrease. In c...
متن کاملKann das Informationsmanagement in Organisationen die diversen Benutzerwünsche in Bezug auf den Einsatz von Endgeräten erfüllen?
Während bislang die adressatengerechte Auswahl von Hard-und Software durch das Informationsmanagement (IM) und deren Zuordnung zu Endanwendern verantwortlich mitgetragen wurde, werden zunehmend Auswahl von Endgeräten durch die User selbst getroffen. Das IM wird mit dieser Wahl konfrontiert. Eine Weigerung der Bedienung von Schnittstellen zu diesen Endgeräten durch das IM wäre motivationshemmend...
متن کاملThe 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 کاملPurification and characterization of a tuliposide-converting enzyme from bulbs of Tulipa gesneriana.
An enzyme that catalyzes the stoichiometric conversion of 6-tuliposide into tulipalin was purified and characterized from bulbs of Tulipa gesneriana. The enzyme appeared to be a dimer, the relative molecular mass (Mr) of each subunit being 34,900; it had maximum activity and stability at neutral pH and moderate temperature. The enzyme preferentially acted on such glucose esters as 6-tuliposides...
