Highly 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 کاملChromatid and chromosome type breakage-fusion-bridge cycles in wheat (Triticum aestivum L.).
During the development of disomic additions of rye (Secale cereale L.) chromosomes to wheat (Triticum aestivum L.), two reverse tandem duplications on wheat chromosomes 3D and 4A were isolated. By virtue of their meiotic pairing, the reverse tandem duplications initiated the chromatid type of the breakage-fusion-bridge (BFB) cycle. This BFB cycle continued through pollen mitoses and in the earl...
متن کاملIMPROVED SOMATIC EMBRYOGENESIS USING L-ASPARAGINE IN WHEAT (Triticum aestivum L.)
Somatic embryos and plants were produced from mature and immature embryo derived callus of wheat. Immature embryo showed a better capacity for somatic embryogenesis and plant regeneration. Presence of 2, 4-D was shown to be essential for induction and maintenance of somatic embryogenesis. Organic nitrogenous additives (L-proline, L-asparagine and casein hydrolysate) marked an effect on somatic ...
متن کاملThe wheat (Triticum aestivum L.) leaf proteome.
The wheat leaf proteome was mapped and partially characterized to function as a comparative template for future wheat research. In total, 404 proteins were visualized, and 277 of these were selected for analysis based on reproducibility and relative quantity. Using a combination of protein and expressed sequence tag database searching, 142 proteins were putatively identified with an identificat...
متن کاملThe effect of hydropriming and halopriming on germination and early growth stage of wheat (Triticum aestivum L.)
In order to study of hydropriming and halopriming on germination and early growth stage of wheat (Triticum aestivum L.) an experiment was carried out in laboratory of the Department of AgroNomy and Plant breeding, Shahrood University of Technology. Seed treatments consisted of T1: control (untreated seeds), T2: soaking in distilled water for 18 h (hydropriming). T3: soaking in -1.2 MPa solution...
