Temperature-dependent growth contributes to long-term cold sensing.

ABSTRACT: Temperature is a key factor in the growth and development of all organisms^1,2. Plants have to interpret temperature fluctuations, over hourly to monthly timescales, to align their growth and development with the seasons. Much is known about how plants respond to acute thermal stresses^3,4, but the mechanisms that integrate long-term temperature exposure remain unknown. The slow, winter-long upregulation of VERNALIZATION INSENSITIVE 3 (VIN3)^5-7, a PHD protein that functions with Polycomb repressive complex 2 to epigenetically silence FLOWERING LOCUS C (FLC) during vernalization, is central to plants interpreting winter progression^5,6,8-11. Here, by a forward genetic screen, we identify two dominant mutations of the transcription factor NTL8 that co
