The Coloration of Anther and Corbicular Pollen

colchicine induced embryogenesis and doubled haploid production in maize (zea mays l.) anther culture

this study involves in vitro androgenesis of zea maysl. via anther culture. combination of two embryoinduction media (imss &amp; ypm) in presence of different colchicine concentrations (0, 100, 200, 250, 300and 400 mg/l ) in the pretreatment medium (iml) andpretreatment duration (0, 3, 6 and 9 days) in twogenotypes (dh5×dh7 and eth-m82) were tested.after colchicine pretreatment, anthers were tr...

Identification of Embryoid-Abundant Genes That Are Temporally Expressed during Pollen Embryogenesis in Wheat Anther Cultures.

Uninucleate microspores in anther cultures of bread wheat (Triticum aestivum cv Pavon) are capable of producing haploid pollen embryoids and plants. To gain an understanding of this alternate pathway of pollen development, we constructed a cDNA library to young pollen embryoids, isolated embryoid-specific genes, and analyzed their expression patterns during morphogenesis. Two embryoid-abundant ...

The effect of plant growth regulators on callogenesis and gametic embryogenesis from anther culture of cucumber (Cucumis sativus L.)

In this study, the effect of plant growth regulators on callogenesis and gametic embryogenesis from anther cultures of cucumber (Cucumis sativus L.) was investigated. A factorial experiment based on Completely Randomized Design with three replications was used in this study. Two cultivars of cucumber (Beta Alfa and Esfahani) were used as first factor and 11 hormone treatments including: control...
