title: Lysine tRNAs from cytoplasm, chloroplasts and mitochondria of the lupin seedling cotyledons.
abstract: 1. The lupin cotyledons contain two cytoplasm-specific lysine tRNAs, one chloroplast-specific, one mitochondria-specific species, and three species common to all the cell compartments investigated; the lysine tRNAs were separated by reversed-phase chromatography (RPC-5). 2. The two cytoplasmic lysine tRNAs are predominant in the tRNALys isolated from the whole tissue. Their level and relative ratios change during germination (Augustyniak & Pawełkiewicz, 1978, Phytochemistry, 17, 15-18). 3. The organellar tRNA constitutes about 20% of the total tRNA in the cotyledons of 7-day-old lupin seedlings.
