Genetic assimilation and the evolution of novelty
Most, if not all, organisms possess the ability to alter their phenotype in direct response to changes in their environment, a phenomenon known as phenotypic plasticity.

Cupins: What are they for?
First, we ought to say what cupins are: cupins are proteins, part of a so-called superfamily that includes enzymes and non-enzyme polypeptides. Since the

Development and evolution of extremely complex flowers
The two very species-rich families Apocynaceae and Orchidaceae contain the most complex flowers in the angiosperms. Although they are not related they show a number

Obdiplostemony: the occurrence of a transitional stage linking robust flower configurations
Obdiplostemony, the two-whorled stamen configuration with outer stamens in alternisepalous position, has been a controversial condition for a long time. Ronse De Craene and Bull-

The developmental genetics of biological robustness
Biological systems face constant perturbations, yet often manage to produce invariable developmental phenotypes. Developmental robustness is a property observed across phyla and recent work in yeast,

Plastic adaptive cleistogamy in Lamium amplexicaule
Cleistogamous plants have the ability to produce closed obligately selfing flowers, and open potentially outcrossed flowers. Flower proportion is known to vary in response to reliable

Plant injury can reset the ageing clock in plants but only slightly alleviates senescence
Senescence is the process of losing fitness when growing old, and is shaped by the trade-off between maintenance and reproduction that makes reproduction more unsure

Excessive sulphur accumulation and ionic storage behaviour identified in species of Acacia (Leguminosae: Mimosoideae)
Thiophores, which are typically desert gypsophytes, accumulate high (2–6 % S dry weight) sulphur concentrations and may possess unique tolerance to environmental stress factors, e.g.

Epigenetics of drought-induced trans-generational plasticity; consequences for range limit development
Offspring phenotypes may be altered by environments that their parents lived in.These environmentally-induced trans-generational effects may be mediated by epigenetic mechanisms such as
