Protein Synthesis in Plants: Specificity and Role of the Cytoplasmic and Organellar Systems(1,2). Indeed it is possible to isolate from plant cells cytoplasmic, mitochondrial and chloroplastic ribosomes that differ in the sedimentation coefficient and in the rRNA composition (3) as well as in the ribosomal proteins (4). In addition different tRNA’s and aminoacyl-tRNA synthetases have been

Functional Characterization of the Initiation Factors of Wheat Germ process is the attachment of ribosomes to preformed mRNA (2), and the reaction can, in part, be reproduced . (3). In further studies it was found that the ribosome attachment reaction could be carried out with a number of eucaryotic mRNAs, in particular with plant viral RNAs (4, 5, 6). Utilizing pa

Hormonal Control of Protein Synthesisof activity of one or more enzymes. In no case is it known how the tissue controls the level of enzyme activity in response to the changed hormone concentration. It is instructive to review the best known of these responses as we try to develop concepts that will allow us to understand them.

The Control of Plant Growth by Protein Kinases their unifying theory it was not clear how cyclic AMP initiated the subsequent molecular events associated with hormone action. Their theory (2.) proposed that the effects of cyclic AMP were mediated by cyclic AMP-dependent protein kinases in the responsive tissue. Since it is the catalytic functio
