^aThe genomic position indicates the location in one of the repeats; there are two copies in the MDV genome.

^bThe sequence of GA (accession no. AF147806) was obtained from GenBank.

^cMd5 (accession no. AF243438) is the reference strain.

^dmdv-miR-M9-5p spans 133374 to 133395; mdv-miR-M9-3p spans 133414 to 133435.

^eND, not determined. Empty cells indicate that the nucleotide is the same as that in the reference strain.
