Quantitative gene regulation at the cell population level can be achieved by two fundamentally different modes of regulation at individual gene copies. A ‘digital’ mode involves binary ON/OFF expression states, with population-level variation ari

Feeling Every Bit of Winter – Distributed Temperature Sensitivity in Vernalization

Autor: Rea L. Antoniou-Kourounioti, Yusheng Zhao, Caroline Dean, Martin Howard

Publikováno v: Frontiers in Plant Science, Vol 12 (2021)

Temperature intrinsically influences all aspects of biochemical and biophysical processes. Organisms have therefore evolved strategies to buffer themselves against thermal perturbations. Many organisms also use temperature signals as cues to align be

Natural variation in autumn expression is the major adaptive determinant distinguishing Arabidopsis FLC haplotypes

In Arabidopsis thaliana, winter is registered during vernalization through the temperature-dependent repression and epigenetic silencing of floral repressor FLOWERING LOCUS C (FLC). Natural Arabidopsis accessions show considerable variation in vernal

Absence of warmth permits epigenetic memory of winter in Arabidopsis

Autor: Jo Hepworth, Rea L. Antoniou-Kourounioti, Rebecca H. Bloomer, Catja Selga, Kristina Berggren, Deborah Cox, Barley R. Collier Harris, Judith A. Irwin, Svante Holm, Torbjörn Säll, Martin Howard, Caroline Dean

Publikováno v: Nature Communications, Vol 9, Iss 1, Pp 1-8 (2018)

Plants use multiple cues to monitor seasonal temperatures. Here, the authors show that Arabidopsis requires not only prolonged cold, but the absence of temperature spikes above 15 °C to epigenetically silence FLC during winter.
