| Topaz is a variety of canola exhibiting a high frequency of embryogenesis in isolated microspore cultures. |
| The tapetal tissue has a secretory role providing essential nutrients required for microspore and pollen grain development. |
| Germination of the microspore begins before it leaves the pollen-sac. |
| Using microspore culture, NRC-PBI developed a superior type of wheat called McKenzie wheat. |
| At the free microspore stage, a material with a similar electron density to sporopollenin fills the whole locule and deposits over the pollen grain wall. |
| Special emphasis is given to the initial stages of microspore embryogenic potential acquirement and the initiation of cell divisions. |
