Chromosome Doubling of Microspore-Derived Plants from Cabbage (Brassica oleracea var. capitata L.) and Broccoli (Brassica oleracea var. italica L.)
Chromosome doubling of microspore-derived plants is an important factor in the practical application of microspore culture technology because breeding programs require a large number of genetically stable, homozygous doubled haploid plants with a high level of fertility. In the present paper, 29 populations of microspore-derived plantlets from cabbage (Brassica oleracea var. capitata) and brocc...
متن کاملEffects of Heat Shock and 2, 4-D Treatment on Morphological and Physiological Characteristics of Microspores and Microspore-Derived Doubled Haploid Plants in Brassica napus L.
Background: Stresses such as heat shock, starvation, or osmotic is essential to lead isolated microspores towards embryogenesis. Despite the effectiveness of stresses in embryogenesis, they exert adverse effects on metabolism and growth of the regenerated plants. Objectives: The effects of heat shock and 2,4-D treatment on total protein content of treated microspores, morphological and physiol...
متن کاملSomatic embryogenesis and cryopreservation of cauliflower ( Brassica oleracea var
Successful efficient whole cauliflower plant regeneration via somatic embryogenesis from root derived callus tissue was achieved. The research confirmed for the first time the capability of mass production of cauliflower somatic embryos through the indirect pathway. The best callus induction and proliferation was on semi solid Murashige and Skoog (MS) medium supplemented with 2, 4-D at 0.15 mg ...
متن کاملDynamics of Calcium during In vitro Microspore Embryogenesis and In vivo Microspore Development in Brassica napus and Solanum melongena
Calcium is widely known to have a role as a signaling molecule in many different processes, including stress response and activation of the embryogenic program. However, there are no direct clues about calcium levels during microspore embryogenesis, an experimental process that combines a developmental switch toward embryogenesis and the simultaneous application of different stressing factors. ...
