Nucleoside 5'-Phosphoramidates Control the Phenylpropanoid Pathway in Vitis vinifera Suspension-Cultured Cells.

ABSTRACT: It is known that cells contain various uncommon nucleotides such as dinucleoside polyphosphates (NpnN's) and adenosine 5'-phosphoramidate (NH2-pA) belonging to nucleoside 5'-phosphoramidates (NH2-pNs). Their cellular levels are enzymatically controlled. Some of them are accumulated in cells under stress, and therefore, they could act as signal molecules. Our previous research carried out in Arabidopsis thaliana and grape (Vitis vinifera) showed that NpnN's induced the expression of genes in the phenylpropanoid pathway and favored the accumulation of their products, which protect plants against stress. Moreover, we found that NH2-pA could play a signaling role in Arabidopsis seedlings. Data presented in this paper show that exogenously applied purine (NH2-pA, NH2-pG) and pyrimidine (NH2-pU,
