Physical mapping of the 5S ribosomal RNA genes on rice chromosome 11.
One 5S ribosomal RNA gene (5S rDNA) locus was localized on chromosome 11 of japonica rice by in situ hybridization. The biotinylated DNA probe used was prepared by direct cloning and direct labeling methods, and the locus was localized to the proximal region of the short arm of chromosome 11 (11p1.1) by imaging methods. The distance between the signal site and the centromere is 4.0 arbitrary units, where the total length of the short arm is 43.3 units. The 5SrDNA locus physically identified and mapped in rice was designated as 5SRrn. The position of the 5S rDNA locus reported here differs from that in indica rice; possible reasons for this difference are discussed. DNA sequences of 5S rDNA are also reported.
