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 purpose of this work was to study in detail with TEM the successive stages of pollen wall
and tapetum development in Dianthus deltoides and to clarify the mechanisms underlying …

The purpose of this work was to study in detail the successive stages of pollen wall
development in Juniperus communis and intimate connection between the microspores and …

For the first time, the developmental events in the course of exine structure establishment
have been traced in detail with TEM in Eupomatia, with the addition of cytochemical tests. A …

The pre-meiotic, meiotic and tetrad stages of development in microsporangia of Alsophila
setosa were studied with particular emphasis on the early establishment of patterning in the …
