Analysis of gene expression during the transition to climacteric phase in carnation flowers (Dianthus caryophyllus L.)
It has been generally thought that in ethylene-sensitive plants such as carnations, senescence proceeds irreversibly once the tissues have entered the climacteric phase. While pre-climacteric petal tissues have a lower sensitivity to ethylene, these tissues are converted to the climacteric phase at a critical point during flower development. In this study, it is demonstrated that the senescence...
متن کاملOxidative stress, antioxidant capacity and ethylene production during ageing of cut carnation (Dianthus caryophyllus) petals
The objective of this work was to study the role of free radicals in relation to ethylene production during ageing of cut carnation petals. Ethylene production by freshly cut flowers was negligible, but 8 d after cutting ethylene production began to increase and reached a peak by day 9, before beginning to decline again. The efflux of electrolytes (membrane damage index) increased 101% and 2 ,7...
متن کاملSequence Analysis of the Genome of Carnation (Dianthus caryophyllus L.)
The whole-genome sequence of carnation (Dianthus caryophyllus L.) cv. 'Francesco' was determined using a combination of different new-generation multiplex sequencing platforms. The total length of the non-redundant sequences was 568,887,315 bp, consisting of 45,088 scaffolds, which covered 91% of the 622 Mb carnation genome estimated by k-mer analysis. The N50 values of contigs and scaffolds we...
متن کاملQuantification of major flavonoids in carnation tissues (Dianthus caryophyllus) as a tool for cultivar discrimination.
One flavone-C-glycoside and two flavonol-O-glycosides were recognized and isolated as the main flavonoidal components in nine different carnation cultivars, and their chemical structures have been determined by spectroscopic methods, including UV detection, MS and NMR. The distribution of these three compounds in flowers, leaves, stems, young sprouts, and roots of each cultivar was evaluated by...
متن کاملIsozymes of Superoxide Dismutase in Mitochondria and Peroxisomes Isolated from Petals of Carnation (Dianthus caryophyllus) during Senescence.
The balance between reactions involving free radicals and processes which ameliorate their effect plays an important role in the regulation of plant senescence. In this study a method was developed to isolate peroxisomes and mitochondria from carnation (Dianthus caryophyllus L. cv Ember) petals. Based on electron microscopy and marker enzyme levels, the proportion of peroxisomes to mitochondria...
