Production 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 کاملProduction of interspecific hybrids between commercial cultivars of the eggplant (Solanum melongena L.) and its wild relative S. torvum.
Interspecific hybrids between cultivars of eggplant (Solanum melongena L.) and its wild relative S. torvum, which has disease resistance and desirable traits for crop improvement, were obtained by cross-hybridization and embryo rescue. Twenty-one hybrid progenies were obtained and examined based on morphological traits, RAPD and ISSR markers. Five of them were confirmed to be true interspecific...
متن کاملInterspecific Crossing between Yam Species (Dioscorea rotundata and Dioscorea bulbifera) through in Vitro Ovule Culture
In the present study, in vitro ovule culture technique was used to obtain interspecific cross combination of Dioscorea rotundata ufenyi and Dioscorea bulbifera wild. Ten days after pollination, ovules were excised and cultured onto 1/2 strength Murashige and Skoog (MS) medium (Basal salt mixture + Vitamins) supplemented with 6% sucrose, 0.7% agar and plant growth hormones such as GA3, BAP, Picr...
متن کاملProduction of L-DOPA(3,4-dihydroxyphenyl-L-alanine) from benzene by using a hybrid pathway.
As an alternative approach to the production of L-DOPA from a cheap raw material, we constructed a hybrid pathway consisting of toluene dioxygenase, toluene cis-glycol dehydrogenase, and tyrosine phenol-lyase. In this pathway, catechol is formed from benzene through the sequential action of toluene dioxygenase and toluene cis-glycol dehydrogenase, and L-DOPA is synthesized from the resulting ca...
متن کاملHybrids and amphiploids of Aegilops ovata L. with Secale cereale L.: production, morphology and fertility.
Hybrids (2n = 3x = 21) between Aegilops ovata and Secale cereale were produced via embryo rescue. Most hybrid morphological traits were intremediate between parents, the plants grew vigorously but were completely sterile. The average frequency of chromosome associations at metaphase I was 19.57-20.19 univalents and 0.40-0.86 rod bivalents. The fertility of the hybrids was restored by doubling t...
