What is Microsporogenesis? - BYJU'S
网页Microsporogenesis is the formation of microspores inside a microsporangium (or pollen sac) by meiotic or reduction division. The formation of pollen grains from the microspores is termed microgametogenesis.
Microsporogenesis - an overview | ScienceDirect Topics
网页Development of microspores from microsporocytes is termed microsporogenesis. There are two basic types of microsporogenesis as determined by the timing of cytokinesis, which is the formation of a plasma membrane and cell …
Microsporogenesis - an overview | ScienceDirect Topics
网页Microsporogenesis is essential for male fertility and requires both the formation of somatic and reproductive cells in the anther and meiotic segregation of homologous chromosomes. Molecular genetic studies have uncovered signaling molecules and transcription factors that play crucial roles in determining the anther cell types and in ...

网页2011年11月3日 · Microsporogenesis begins with meiosis of microspore mother cells (MMC) and ends with formation of polarized haploid microspores. During this process, a diploid sporophyte becomes haploid microspores through meiosis. Microgametogenesis starts at the release of microspores from tetrads.
MOLECULAR GENETIC ANALYSES OF MICROSPOROGENESIS …
网页Genetic analyses have demonstrated the function of some of these genes in specifying stamen identity, regulating anther cell division and differentiation, controlling male meiosis, supporting pollen development, and promoting anther dehiscence.

网页2021年5月16日 · Microsporogenesis, an important process during plant reproduction, includes a series of developmental stages from sporulation cells to microspores (Ronceret and Vielle-Calzada 2015). Normal gamete formation can affected by any unpredictable alterations during meiotic (Brownfield and Köhler 2011).
