Photochlorophyll Biosynthesis in Cucumber (Cucumis sativus, L.) Cotyledons.
The formation of protochlorophyllide and protochlorophyllide phytyl ester was investigated during etioplast biogenesis in order to study the biosynthetic relation of these two compounds. Protochlorophyllide accumulates slowly during the first 2 days of germination, its rate of formation increases sharply during the 3rd day, and then it decreases. Protochlorophyllide phytyl ester starts accumula...
متن کاملInduction of somatic embryogenesis in absence of exogenous auxin in cucumber (Cucumis sativus L.)
Induction of somatic embryogenesis in absence of exogenous auxin can clarify some basic concepts of somatic embryogenesis. Explants from leaf and petiole of Cucumber (Cucumis sativus) were used in this experiment for somatic embryogenesis using three different modified B5 basal media; boron and 2,4-D but no IAA as control (I), boron and IAA but no 2,4-D (II) and no boron, 2,4-D and IAA (III). ...
متن کاملSomatic Embryogenesis and Plant Regeneration from Embryonic Axes and Cotyledons Explants of Tea (Camellia sinenesis L.)
In the present study, 2, 4-dichlorophenoxyacetic acid (2, 4-D) was assessed individually for its effectiveness to induce somatic embryogenesis in tea (Camellia sinenesis L.). Embryonic axes and cotyledons explants were dissected from the seeds. Explants were cultured on Murashige and Skoog (MS) medium containing 0, 1 and 5 mM 2, 4-D alone for embryonic axes and 0, 1 and 5 mM 2, 4-D along with 0...
متن کاملMicrobody Malate Dehydrogenase Isozyme in Cotyledons of Cucumis sativus L. during Development.
The properties of the microbody malate dehydrogenase (EC 1.1.1.37) (MDH) isozyme from cotyledons of Cucumus sativus L. were compared during development. It is concluded that the isozyme remains unaltered, despite the transition from glyoxysomal to peroxisomal function that occurs during greening of the cotyledons. This conclusion is based on electrophoretic behavior, chromatographic elution fro...
متن کاملIn Vivo Pathway of Oleate and Linoleate Desaturation in Developing Cotyledons of Cucumis sativus L. Seedlings.
Exogenous [1-(14)C]oleic acid and [1-(14)C]linoleic acid were taken up and esterified to complex lipids by greening cucumber (Cucumis sativus L.) cotyledons. Both (14)C-labeled fatty acids were initially esterified to phosphatidylcholine prior to eventual accumulation in triacylglycerols and galactolipids. Kinetic data suggest that esterification occurs prior to desaturation and that phosphatid...
