| A comparative study of free amino acid content in healthy and virus diseased tobacco leaves was carried out by author throughout the gorwing season from June to November of 1963. The methods of qualitative analysis of free amino acids applied in this experiment is followed by Moore and Stein. 1,2 Free amino acids determined in this experiment are shown in Fig. Ⅰ, Ⅱ and Table Ⅰ. As the figure and the table are shown, four more amino acids such as a spartic acid, glutamic acid, tyrosine and phenylalanine are detected in the healthy leaves; these four additional amino acids in the healthy leaves are conspicuous. More quantities of asparagine and alanine are detected in the diseased leaves than the healthy leaves and more quantities of tryptophan is detected in the healthy leaves. It is presumed that such amino acids as tyrosine and phenyllanine are decreased by the incooperation of free amino acid to TMV protein in the process of the process of the leaf protein metabolism which is caused by TMV-RNA trapping action in the diseased leaf protoplasm. It is thought that the decrease of asparagine and the increase of asparic acid in the healthy leaves are the results of in incooperaton of NH2, produced by the protein dissimilation in the diseased leaves, to aspartic acid; it's reaction is caused by the respiration of the diseased leaves accelerated by TMV attack. It is presumed, consequently, that the check of the diseased tobacco leave growth is influenced by the reduction of such amino acids as tryptophane and glutamic acid, which reduction may be due to the abnormal protein metabolism and the action of certain enzyme caused by TMV attack on host protoplast. |
