Functional pollen is needed to successfully complete fertilization. Pollen is formed inside the
anthers following a specific sequence of developmental stages, from microsporocyte …

The mega-diversity of herbivorous insects is attributed to their co-evolutionary associations
with plants. Despite abundant studies on insect-plant interactions, we do not know whether …

Next to pollen, stamens of flowering plants often produce microstructures, called orbicules,
lining the locules. Although the existence of orbicules has been known since 1865, their …

The present classification of extant flowering plants (Magnoliopsida) updates and revises
those presented previously by bringing together the vast majority of new information …

The ornately geometric walls of pollen grains have inspired scientists for decades. We show
that the evolved diversity of these patterns is entirely recapitulated by a biophysical model in …

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 …

A combined phylogenetic analysis of the Aristolochioideae was conducted based on 72
morphological characters and molecular data sets (matK gene, trnK intron, trnL intron, trnL …

Phylogenetic analyses of molecular and morphological data, revised in this study, shed light
on long‐standing controversies on the early evolution of angiosperm pollen. Although …

A phylogenetic analysis was conducted to examine the monophyly and relationships of the
four broadly defined genera of Aristolochiaceae. Seventy-two morphological characters …
