Natural environments require organisms to possess robust mechanisms allowing responses
to seasonal trends. In Arabidopsis halleri, the flowering regulator AhgFLC shows …

Diel and seasonal oscillations are two major environmental changes in nature. While
organisms cope with the former by the well-characterized mechanism of the circadian clock …

Previous studies in A rabidopsis thaliana have identified several histone methylation
enzymes, including ARABIDOPSIS TRITHORAX1 (ATX 1)/SET DOMAIN GROUP 27 (SDG …

Plants have a remarkable ability to react to seasonal changes by synchronizing life-cycle
transitions with environmental conditions. We addressed the question of how transcriptional …

Gene regulatory mechanisms are often defined in studies performed in the laboratory but
are seldom validated for natural habitat conditions, ie, in natura. Vernalization, the promotion …

Selective, tissue-specific gene expression is facilitated by the epigenetic modification
H3K27me3 (trimethylation of lysine 27 on histone H3) in plants and animals. Much remains …

In Arabidopsis, the rapid‐flowering summer‐annual versus the vernalization‐requiring
winter‐annual growth habit is determined by natural variation in FRIGIDA (FRI) and …

Flowering represents a crucial transition from a vegetative to a reproductive phase of the
plant life cycle. Despite extensive studies, the molecular mechanisms controlling flowering …

Plant life-long organogenesis involves sequential, time and tissue specific expression of
developmental genes. This requires activities of Polycomb Group (PcG) and trithorax Group …

Plants remember their exposure to environmental changes and respond more effectively the
next time they encounter a similar change by flexibly altering gene expression. Epigenetic …
