George Coupland is currently a Director of the Max<br />
Planck Institute (MPI) for Plant Breeding Research in<br />
Cologne. He leads the department of Plant Developmental<br />
Biology. He received an Honours degree in Microbiology from the University<br />
of Glasgow (UK) in 1981. His doctoral work was in the Department of Molecular<br />
Biology, University of Edinburgh (UK), where he studied the mechanisms of<br />
conjugation in bacteria. In 1985, he received a Royal Society Fellowship and an<br />
EMBO Fellowship to carry out post-doctoral research at the University of Cologne<br />
in the department of Peter Starlinger. There he developed methods to analyze the<br />
function of maize transposable elements in transgenic tobacco plants. In 1989, he<br />
returned to the UK and began his own group at the newly formed John Innes Centre<br />
in Norwich (UK).<br />
Between 1989 and 2001, the Coupland lab developed Arabidopsis as a model<br />
system to study the seasonal control of flowering by environmental cues. The group<br />
was among the first to isolate genes that regulate flowering time and those required<br />
for plant circadian clock function. This led to an influential model of how plants<br />
detect seasonal changes in day length. He was appointed a Director at the MPI for<br />
Plant Breeding Research in 2001. There his group has demonstrated the multiple<br />
regulatory layers of transcriptional and post-translational regulation that contribute<br />
to day length measurement. They have also studied the function of flowering<br />
pathway components in different organs of the plant, leading to the identification<br />
of a systemic signal transmitted from the leaves to the apex where it induces flower<br />
development. Recently they have studied how these pathways evolve to confer differences<br />
in flowering behaviour between annual and perennial species.<br />
