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 used to track structural and functional evolution in plants as well as to investigate the
problems relative to plant classification. Pollen characters including ornamentation, shape …

The aperture on the pollen surface provides an exit for the emerging pollen tube. Apertures
exhibit huge morphological variation across plant species—grasses, including rice, possess …

Palyno‐anatomical study of monocots taxa using Light and Scanning Electron Microscopy
(SEM) was first time conducted with a view to evaluating their taxonomic significance …

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 …

• 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 …

Palynology is the science of palynomorphs, a general term for all entities found in
palynological preparations (eg, pollen, spores, cysts, diatoms). A dominating object of the …

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

The developmental events in the periplasmic space and cytoplasm of microspores of
Chamaedorea microspadix during sporoderm ontogeny have been traced in detail from …
