Slow Growth (IMAGE) John Innes Centre Caption NTL8 is expressed in a restricted region in Arabidopsis in the warm (shown here is the root tip), but over a long period in the cold the protein gradually accumulates and expands to a larger region. Mathematical modelling showed that the slowing down of growth in the cold alone is sufficient to produce this response, suggesting a new temperature sensing mechanism.
