This paper presents the first broad overview of three main features of microsporogenesis
(male meiosis) in angiosperms: cytokinesis (cell division), intersporal wall formation, and …

Microsporogenesis is highly labile in early-branching angiosperms, ie, those with mostly
sulcate pollen, compared with the tricolpate and tricolpate-derived eudicots. New records of …

Two basic types of cytokinesis are recognised during microsporogenesis, characterised by
different tetrad morphologies. The successive type is more common in monocots but the …

The eudicot clade of angiosperms is characterised by simultaneous microsporogenesis and
tricolpate pollen apertures. Successive microsporogenesis, where a distinct dyad stage …

Although the pollen grains produced in monocots are predominantly monosulcate (or
monoporate), other aperture types are also found within this taxonomic group, such as the …

The process of microsporogenesis and microgametogenesis was studied at the
ultrastructural level in wild-type Arabidopsis thaliana ecotype Wassilewskija to provide a …

An understanding of the processes of plant reproduction is increasingly important in the
exploitation of plant resources. Microspore formation is a major event in the life cycles of …

Pollen grains are produced during meiosis (microsporogenesis), in the anthers of flower
buds. Apertures are usually formed at the last points of contact between the microspores …

In flowering plants, male meiosis occurs in the microsporocyte to produce four microspores,
each of which develops into a pollen grain. Here we describe four mutant alleles of …

Abstract Background and Aims In flowering plants, microsporogenesis is accompanied by
various types of cytoplasmic partitioning (cytokinesis). Patterns of male cytokinesis are …
