From: The CRF domain defines Cytokinin Response Factor proteins in plants

Novel Tomato CRF genes are induced by cytokinin. Induction of four Tomato CRF genes (SlCRFs) by 5 μM cytokinin (BA) after 2 h in leaves of 20 d old plants as shown by RT-PCR. A beta-tubulin control showing no change in expression is also shown from the same representative experiment.
