A 0.9 kb double stranded cDNA of foot and mouth disease virus (FMDV) Type Asia 1, 63/72 was cloned in an expression vector, pUR222. A protein of 38 kd was produced by the clone which reacted with the antibodies raised against the virus. A 20 kd protein which may be derived from the 38 kd protein contained the antigenic epitopes of the protein VP1 of the(More)

Our current understanding of the evolution of the histone gene family suffers from a lack of information on plant histone genes. With a view to gathering some much needed information on these genes, we studied a rice genomic clone in pBR322 carrying H2A, H2B and H4 histone genes on a DNA fragment of 6.64 kilobases (kb). A restriction map of the insert was(More)
The 5S-rRNA from the ungerminated and 48-h-germinated rice embryos differs from the wheat, rye and maize by two nucleotides. The 48-h-germinated embryos contain another species of 5S-rRNA which differs by 3 nucleotides from the ungerminated embryos, thereby showing the expression of two 5S-rRNA genes during germination. The 5S-rRNA genes are present in(More)
Three direct repeats of 320, 340 and 238 nucleotides were detected upstream to the 5' end of the 18S rRNA gene of an rDNA unit present on a 9.8 kb EcoRI fragment of the rice DNA. The primer extension analysis showed that the site of initiation of transcription is in the 1st repeat at an A, the 623rd nucleotide upstream to the 5' end of the 18S rRNA gene.(More)
