Generation of Doubled Haploid Transgenic Wheat Lines by Microspore Transformation
Microspores can be induced to develop homozygous doubled haploid plants in a single generation. In the present experiments androgenic microspores of wheat have been genetically transformed and developed into mature homozygous transgenic plants. Two different transformation techniques were investigated, one employing electroporation and the other co-cultivation with Agrobacterium tumefaciens. Di...
متن کاملHighly Efficient Doubled-Haploid Production in Wheat (Triticum aestivum L.) via Induced Microspore Embryogenesis
haploid plant per floret (Devaux, 1988). Androgenesis induction in microspores may be affected by various An efficient doubled-haploid production technology that induces factors which cause low induction efficiency and by gehomozygosity can greatly reduce the time and cost of cultivar developnotype dependence (Dunwell, 1985). Most advances toment. Low efficiency of doubled-haploid production pr...
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 کاملIn vitro induction of haploid plants in unpollinated ovules, anther and microspore culture of Cucumis sativus
In order to increase the yield of haploid cucumber plants obtained from in vitro culture of unpollinated ovules, anther and microspore, we have studied several factors: the nature and concentration of plant growth regulators, the genotypes, the flower bud lengths, and the stages of microspore development. Among the different growth regulators tested, thidiazuron (TDZ) was the best for gynogenes...
