  1. Expression values are expressed as normalized read number. ‘Fold change’ is calculated as FR reads/ISR reads. One annotation is given for each contig. Annotations of the two best hits for each contig (E value ≤ 1.0E-3) are available in Additional file 1. ISR, Initiating storage root, FR, Fibrous root. * - Read counts were changed from zero to one to enable ‘Fold change’ calculation.
