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 کاملRegulation of Mitochondrial Function and Biogenesis in Cucumber (Cucumis sativus L.) Cotyledons during Early Seedling Growth.
The aim of this work was to characterize the respiratory metabolism of the greening cotyledons of cucumber (Cucumis sativus L.) during early seedling growth and to investigate how this is integrated with changes in mitochondrial biogenesis and function. In light-grown cotyledons, lipid mobilization extended from germination to 6 days postimbibition, reaching a maximum at 3 to 4 days postimbibit...
متن کاملEffects of Acifluorfen on Endogenous Antioxidants and Protective Enzymes in Cucumber (Cucumis sativus L.) Cotyledons.
The herbicide acifluorfen (2-chloro-4-(trifluoromethyl)phenoxy-2-nitrobenzoate) causes strong photooxidative destruction of pigments and lipids in sensitive plant species. Antioxidants and oxygen radical scavengers slow the bleaching action of the herbicide. The effect of acifluorfen on glutathione and ascorbate levels in cucumber (Cucumis sativus L.) cotyledon discs was investigated to assess ...
متن کاملAssessment of genetic variation in cucumber ( Cucumis sativus L . ) genotypes
In this research, twenty genotypes of cucumber (Cucumis sativus) were studied that were collected from different geographical regions. The experiment was conducted as a randomized complete Block Design (RCBD) with four replications in Greenhouse. Data was collected on morphological features, yield and components of yield of cucumber which include: Total fruit yield per pickling, Fruit number pe...
متن کاملAgrobacterium-Mediated Transformation in Cucumber (Cucumis sativus L.)
Introduction. Cucumber (Cucumis sativus L.) is an important horticultural crop. Its fruits are used for slicing and pickling and juice extraction worldwide. In India, both the fruits and seeds have long been used in the manufacture of traditional medicines that act as skin conditioners, diuretics and body coolants. Thus, cucumber is a potential candidate for an edible vaccine (6). In India, stu...
