Diurnal gene expression levels at four hour intervals over two seasons. Gene expression for apple Gigantea (GI) and BBX1 in apple leaf tissue and fruit skin tissue labelled, all other genes are fruit skin results. Other genes tested were light-associated COP1, HY5, and UVR8, temperature-linked genes CBF2 and HSFA2a and BBX genes 15, 33, and 51 from BBX group IV over two seasons. Expression results were normalised to Actin and error bars are SE of four technical replicates. Daylight hours were from 0640 h to 2040 h for season 1 and from 0700 h to 2000 h for season 2, rounded to the nearest 10 min. Black bars indicate night.
