Heterogeneity of the ribosomal RNA gene clusters in rice

  • Kiyoharu Oono

A discrete heterogeneity has been observed in rice rRNA gene clusters after EcoRI digestion of rice nuclear DNA followed by Southern image hybridization. EcoRI digestion generates the two repeating sequences, 5.0×106 and 5.2×106 daltons, which code for both 25S and 17S rice rRNA.
