May 1 ~ May 3###Meiosis of microspore mother cell stage###Nucelli continue projection
A row of sporogenous cells derived from archesporial cells produced a large number of microspore mother cells after several mitotic divisions (Fig.
Each microspore mother cell undergoes meiosis; during which M.
microspore mother cells (Microsporocytes), were also detectable (Fig 1B).
A sharp correlation was observed between division in microspore mother cells (M.
Each diploid microspore mother cell
produces four haploid microspores.
There was a significant correlation between microspore mother cell
divisions and anther's tapetum development that is coincides with other reports for dicotyledonous plants [7,10,6].
In Hordeum vulgare, plastids are scarce in the microspore mother cell
striata is a continuous process for descriptive purposes of the structure and ultrastructural details, we distinguished five stages of development: microspore mother cell stage followed by meiosis, tetrads, free young microspores, vacuolated pollen, and mature pollen grains at dehiscence.
These cells are closely arranged in the entire pollen chamber and further develop into microspore mother cell.
The distinctive shape of the microspore, with its sharply angled proximal ridge, is a result of the developmental pattern of the microspore mother cells
The meiotic division in the MMC is synchronic with the microspore mother cells
