plants. Northern Blot Analysis of the progeny of APMS-6A × APMS-6B (lane 1) and APMS-6A × BR-1870 (lane 2) crosses using the orfB gene probe. (A) Equal loading of RNA samples was shown by visualization of the ribosomal RNA band visualized by staining the gel in ethidium bromide before blotting. (B) Autoradiograph of the blot after probing with the rice orfB gene-specific probe.
