Notes:
The incorporation of 14C-labelled phenylalanine into proteins of the mitochondrial systems obtained from 48-h germinating seeds of Vigna sinensis (L.) Savi can be stimulated by polyuridylic acid [poly (U)] and depressed by rifampicin, which is, however, ineffective if poly (U) is allowed to interact with the incorporating system before the antibiotic has access to it.A system consisting of a mitochondrial S-100 fraction and ribosomes from the same source with other cofactors can bring about polymerization of phenylalanine.The incorporation of 14C-labelled uracil into RNA by the plant mitochondria is greatly dependent on the exogenous addition of adenine, guanine, cytosine and also on 5-phosphoribosyl-l-pyrophosphate (5-PRPP). It is greatly suppressed by rifampicin and ethidium bromide.
