Regulation of Senescence in Carnation (Dianthus caryophyllus): Effect of Abscisic Acid and Carbon Dioxide on Ethylene Production.
Abscisic acid hastened senescence of carnation flowers and this was preceded by stimulation of accelerated ethylene production. Carbon dioxide delayed the onset of autocatalytic ethylene production in flowers regardless of treatment with abscisic acid. Flowers exhibited a low and transient climacteric of ethylene production without wilting while in 4% carbon dioxide and underwent accelerated et...
متن کاملComparison of mRNA levels of three ethylene receptors in senescing flowers of carnation (Dianthus caryophyllus L.).
Three ethylene receptor genes, DC-ERS1, DC-ERS2 and DC-ETR1, were previously identified in carnation (Dianthus caryophyllus L.). Here, the presence of mRNAs for respective genes in flower tissues and their changes during flower senescence are investigated by Northern blot analysis. DC-ERS2 and DC-ETR1 mRNAs were present in considerable amounts in petals, ovaries and styles of the flower at the ...
متن کاملProduction of doubled haploid plants of carnation (Dianthus caryophyllus L.) by pseudofertilized ovule culture
Doubled haploids of carnation (Dianthus caryophyllus L.) were obtained by pseudofertilized ovule culture. Emasculated ̄ower buds of carnation were pollinated with pollen inactivated by Xray irradiation. After 2±3 weeks, the ovaries were explanted and were cultured on solid MS medium containing 2 mM NAA, 2 mM BAP and 6% sucrose. Regenerated plants(R0) were morphologically different from the moth...
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...
