A combinatorial approach to angiosperm pollen morphology [PDF]
, 2016 Angiosperms (flowering plants) are strikingly diverse. This is clearly expressed in the morphology of their pollen grains, which are characterized by enormous variety in their shape and patterning.

Fullerene-based symmetry in Hibiscus rosa-sinensis pollen. [PDF]
PLoS ONE, 2014 The fullerene molecule belongs to the so-called super materials. The compound is interesting due to its spherical configuration where atoms occupy positions forming a mechanically stable structure.

A method to search for optimal field allocations of transgenic maize in the context of co-existence [PDF]
, 2008 Spatially isolating genetically modified (GM) maize fields from non-GM maize fields is a robust on-farm measure to keep the adventitious presence of GM material in the harvest of neighboring fields due to cross-fertilizations below the European ...

Molecular cloning and transcriptional activity of a new Petunia calreticulin gene involved in pistil transmitting tract maturation, progamic phase, and double fertilization [PDF]
, 2013 Calreticulin (CRT) is a highly conserved and ubiquitously expressed Ca2+-binding protein in multicellular eukaryotes. As an endoplasmic reticulum-resident protein, CRT plays a key role in many cellular processes including Ca2+ storage and release ...

Contribution of pollen to atmospheric ice nuclei concentrations [PDF]
Atmospheric Chemistry and Physics, 2014 Recent studies have suggested that the ice-nucleating ability of some types of pollen is derived from non-proteinaceous macromolecules. These macromolecules may become dispersed by the rupturing of the pollen grain during wetting and drying cycles in the

Evidence for a role of Arabidopsis CDT1 proteins in gametophyte development and maintenance of genome integrity [PDF]
, 2012 Meristems retain the ability to divide throughout the life cycle of plants, which can last for over 1000 years in some species. Furthermore, the germline is not laid down early during embryogenesis but originates from the meristematic cells relatively ...
