Zotz and colleagues ask for a re-evaluation of the occurrence, evolution, and function of the velamen radicum in both terrestrial and epiphytic angiosperms

Plants and Pinatubo, Prestahnukur, Popocatépetl…
Plants are generally sessile organisms that, unlike their puny animal ‘cousins’, can’t get up and run away if the environment is not to their liking. Botanicals by-and-large put up and shut up. Accordingly, that...

Theoretical approach to predicting petal wettability
This model predicts petal surface wettability by considering the additive effects of the geometries of the epidermal cells and the structured cuticle.
Growth and cellular patterns in petal epidermis of Antirrhinum
Analysis of cellular patterns in plant organs provides information about the orientation of cell divisions and predominant growth directions. Raczyńska-Szajgin and Nakielski study patterns in the epidermis of...
Silica nanoparticles and structural leaf coloration
Blue iridescence is produced by both the helicoidal wall and silica nanoparticles in the helicoid.

Molecular genetics of cuticle formation in Prunus
During growth, the fruit surface of sweet cherry, Prunus avium, expands rapidly whilst only a relatively small amount of new cuticular material is produced, often leading to the formation of microscopic cracks in the...
Labellar micromorphology of Zygopetalinae
Molecular evidence indicates that the orchid subtribe Zygopetalinae is sister to Maxillariinae. Davies and Stpiczyńska show that the labellar micromorphology of Zygopetalinae is less diverse than that of Maxillariinae...
Why do petals have conical epidermal cells? (Review)
The conical epidermal cells found on the petals of most Angiosperm species are so widespread that they have been used as markers of petal identity, but their function has only been analysed in recent years. Whitney et...
ERECTA gene and leaf cellular development
<i>ERECTA</i> gene and leaf cellular development The ERECTA gene plays a role in the balance between epidermal cell expansion and division in leaves. Tisné et al. perform spatial and temporal analyses of...
Natural variation in arabidopsis stomatal abundance
Our understanding of stomatal development in Arabidopsis thaliana is based on mutants with aberrant, often lethal phenotypes. Through a comprehensive analysis of stomatal abundance in wild A. thaliana accessions...
