Abstract:
During isolation of total ribonucleic acids from white lupin (Lupinus albus) and their subsequent separation by 10% polyacrylamide gel electrophoresis, a fast migrating RNA band is very well separated. The nucleotide sequence analysis of 76 nucleotide long sequence with many modified nucleosides was found to be identical with that of tyrosine specific tRNA of yellow lupin seeds (Lupinus luteus) and wheat germ (Triticum aestivum). Also this tRNA(Tyr) is identical with plant amber suppressor tRNA. The presented approach offers a very rapid method of purification of plant tRNA with UAG suppressor activity.
