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 کاملTranscript profiling and identification of molecular markers for early microspore embryogenesis in Brassica napus.
Isolated microspores of Brassica napus are developmentally programmed to form gametes; however, microspores can be reprogrammed through stress treatments to undergo appropriate divisions and form embryos. We are interested in the identification and isolation of factors and genes associated with the induction and establishment of embryogenesis in isolated microspores. Standard and normalized cDN...

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. ...
متن کاملZygotic embryogenesis versus somatic embryogenesis
This review will summarize molecular and genetic analyses aimed at identifying the mechanisms underlying the sequence of events during plant zygotic embryogenesis. These events are being studied in parallel with the histological and morphological analyses of somatic embryogenesis. The strength and limitations of somatic embryogenesis as a model system will be discussed briefly. The formation of...
