Relative amounts of putative VRN1 and VRN2 orthologue transcripts as compared with Actin transcript levels in the leaves of field-grown timothy plants at different developmental stages. Samples were harvested from vernalized plants of spring growth during June and regrowth during July–August. The leaves of individual plants were classified according to the developmental stage of the apex. Data are the mean ± s.e. of 3–4 plants. The transition from vegetative to reproductive stage occurs at apex stage A3–A4.
