Key message Overview of pollen development. Abstract Male gametophyte development of
angiosperms is a complex process that requires coordinated activity of different cell types …

Recent attempts to address the long-debated 'origin'of the angiosperms depend on a
phylogenetic framework derived from a matrix of taxa versus characters; most assume that …

Although they are relative latecomers on the evolutionary scene, having emerged only 135?
170 million years ago, angiosperms—or flowering plants—are the most diverse and species …

Although temporal calibration is widely recognized as critical for obtaining accurate
divergence-time estimates using molecular dating methods, few studies have evaluated the …

Plants have utterly transformed the planet, but testing hypotheses of causality requires a
reliable time‐scale for plant evolution. While clock methods have been extensively …

• Premise of the study: While we have a good understanding of how co‐flowering plants
interact via pollinator foraging, we still know very little about how plants interact via …

Exine, the outer plant pollen wall, has elaborate species-specific patterns, provides a
protective barrier for male gametophytes, and serves as a mediator of strong and species …

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 …

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 …
