A histological study of microsporogenesis in Tarenna gracilipes (Rubiaceae)
, 2005 We studied the microsporogenesis in Tarenna gracilipes (Hayata) Ohwi, with special attention to the mode of exine deposition and tapetum development. We based this research on light (LM), scanning electron (SEM) and transmission electron microscopic (TEM)

Preliminary Investigation of Microsporogenesis of Genic-cytoplasmic Male-sterile Pigeonpea [PDF]
, 1994 Preliminary observations of microsporogenesis of a genetic-cytoplasmic male sterile line showed that the development of sporogenous tissue and the progression into PMCs was normal.

Microsporogenesis and male gametogenesis in Jatropha curcas L. (Euphorbiaceae) [PDF]
, 2007 Microsporogenesis and male gametogenesis of Jatropha curcas L. (Euphorbiaceae) was studied in order to provide additional data on this poorly studied family. Male flowers of J. curcas have ten stamens, which each bear four microsporangia. The development

Male gametogenesis in flowering plants
Frontiers in Sustainable Food SystemsThe life cycles of plants are characterized by significant alternations between the diploid sporophytic and the haploid gametophytic generations. Meiosis and fertilization are the prerequisites for achieving the alternation of generations.

Competitive and cooperative behavior of cells in angiosperms microsporogenesis
, 2016 Aim. A comparative cytological analysis of intra- and intertissue cytomictic interactions in early microsporogenesis of mono- and dicotyledonous plants was performed using two cellular systems: microsporocytes and tapetum. Methods.

Premeiotic microsporocyte cell shape influences shape of tetrads during microsporogenesis
, 2012 Angiosperm microspores are grouped into tetrads before they mature into functional pollen grains. This tetrad stage is an important step in microsporogenesis. Tetrad shapes are diverse across angiosperms, with high levels of variation sometimes occurring

Floral morphology and embryological features of anther development in Renanthera imschootiana
Guangxi ZhiwuThere are few data on the rare and endangered orchids of Renanthera Lour. Floral morphology and embryological features of anther development in R. imschootiana were investigated, and the taxonomic significance of R. imschootiana was analyzed by comparing

The homeotic protein AGAMOUS controls microsporogenesis by regulation of SPOROCYTELESS
, 2004 The Arabidopsis homeotic gene AGAMOUS (AG) is necessary for the specification of reproductive organs (stamens and carpels) during the early steps of flower development.
