Group Leader Royal Society Professor Building Robustness in Crops (BRiC)

The Dean lab focuses on how plants sense and remember winter.

The group started with three quite different questions:

  • Why do some plants overwinter before flowering?
  • How do plants remember cold exposure?
  • How do flowering mechanisms adapt to different winters?

Their genetic and molecular experiments addressing these questions converged onto how one gene is regulated. This has led them into a detailed dissection of chromatin and antisense RNA regulation of the floral repressor FLOWERING LOCUS C (FLC).

The lab’s activities currently focus on:

  • Quantitative variation in FLC expression – This influences whether a plant overwinters before flowering and is through an antisense-linked chromatin mechanism
  • Epigenetic switching – Plants remember they have experienced winter in a process called vernalization. This is an epigenetic silencing of FLC expression through a cis-based, Polycomb switching mechanism
  • Natural variation – Arabidopsis thaliana adaptation to different latitudes has involved noncoding polymorphisms within FLC that confer natural variation in flowering and vernalization response
