The study of pollen should encompass all structural and ornamental aspects of the grain.
Pollen morphology is studied using LM and SEM and is important to visualize the general …

Despite numerous attempts to elucidate the developmental mechanisms responsible for the
observed diversity of pollen and spore walls, the processes involved remained obscure until …

The review is devoted to the analysis and generalization of modern knowledge about the
mechanisms underlying the ontogeny of the male gametophyte envelope. New and earlier …

Abstract Background and Aims Decades of research have attempted to elucidate the
underlying developmental mechanisms that give rise to the enormous diversity of pollen and …

New experimental modeling of exine has been undertaken to verify general ideas on the
participation of self-assembly processes in sporoderm development. Our aim was to confirm …

We have attempted to elucidate the underlying mechanisms of sporoderm development and
pattern determination in Plantago major through a detailed ontogenetic study, using …

After detailing the exine ontogeny, our purpose was to find out whether the sequence of
sporoderm developmental events corresponds to self-assembling micellar mesophases …

A growing body of experimental data obtained from sporoderm ontogenetic studies led to
the appearance of the 'micellar'hypothesis. The hypothesis is that the sequence of …

The developmental events in the periplasmic space and the cytoplasm of microspores of
Magnolia sieboldii during microspore ontogeny have been traced with transmission electron …

For the first time, the developmental events in the course of complicated exine structure
establishment have been traced in detail with transmission electron microscope in the …
