In somatic cell division, cytokinesis is the final step of the cell cycle and physically divides
the mother cytoplasm into two daughter cells. In the meiotic cell division, however, pollen …

Pollen grains, the male gametophytes of seed plants, surround themselves with a complex
pollen wall for protection from various environmental stresses. The deposition and assembly …

Pollen grains of flowering plants display a fascinating diversity of forms. The observed
diversity is determined by the developmental mechanisms involved in the establishment of …

The genus Ceroxylon is revised and twelve species are recognized. A total of 228
specimens from 19 herbaria were studied and field work was carried out in four countries. A …

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

The contribution of developmental constraints and selective forces to the determination of
evolutionary patterns is an important and unsolved question. We test whether the long‐term …

To date, the effect of habitat conditions on the characteristics of pollen has not been
extensively investigated; however, it needs to be remembered that it may be highly …

Monocots, with ca. 65,000 species in 78 families and 12 orders as classified by the
Angiosperm Phylogeny Group (Angiosperm Phylogeny Group III, 2009), have traditionally …

• Premise of the study: Pollen grains of flowering plants display a fascinating diversity of
forms, in spite of their minute size. The observed diversity is determined by the …

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 …
