Phenotypic variation is traditionally parsed into components that are directed by genetic and
environmental variation. The line between these two components is blurred by inherited …

Plants rely heavily on environmental cues to control the timing of developmental transitions.
We are beginning to better understand what determines the timing of two of these …

Winter wheat and barley varieties require an extended exposure to low temperatures to
accelerate flowering (vernalization), whereas spring varieties do not have this requirement …

Floral development at the Arabidopsis shoot apical meristem occurs in response to
environmental cues that are perceived in different tissues. Photoperiod is detected in the …

MEDEA (MEA) is an Arabidopsis Polycomb group gene that is imprinted in the endosperm.
The maternal allele is expressed and the paternal allele is silent. MEA is controlled by …

The plant Polycomb‐group (Pc‐G) protein CURLY LEAF (CLF) is required to repress targets
such as AGAMOUS (AG) and SHOOTMERISTEMLESS (STM). Using chromatin …

In Arabidopsis thaliana, the promotion of flowering by cold temperatures, vernalization, is
regulated via a floral-repressive MADS box transcription factor, FLOWERING LOCUS C …

Vernalization is the process by which sensing a prolonged exposure to winter cold leads to
competence to flower in the spring. In winter annual Arabidopsis thaliana accessions …

Imprinted genes are expressed predominantly from either their paternal or their maternal
allele. To date, all imprinted genes identified in plants are expressed in the endosperm. In …

Vernalization is the acceleration of flowering by prolonged cold that aligns the onset of
reproductive development with spring conditions. A key step of vernalization in Arabidopsis …
