“…Moreover, it was shown that AT appeared during wilting even without D-Trp addition. The presence of L-AT in Ephedra distachia was communicated by Song et al [37] and in plants of other species by Markova and Gamburg, [30]. Yu et al [13] found AT and MT in tomato young leaves; in Ginkgo male flowers only AT; in coconut milk MT and AT.…”

“…It was observed that MT formed and accumulated in fruits, seeds and seedlings [13,29,30,[36][37][38] as well as in wheat sseedling's roots [28] and in vitro cultured cells [19,30,37]. It is evident that other physiological processes in plants were also accompanied by MT formation and accumulation.…”

“…Liang and Anderson [44] communicated that N-acetyl-L-Trp was contained in cultural liquid of fungus Claviceps purpurea. Then, Song et al [37] found MT in tissue culture of Ephedra distachya and showed that it contained L-Trp. This contradicted to widespread in that time opinion that endogenous MT contains D-Trp.…”

Drought stress in plants is accompanied by several metabolic changes. One of them is the appearance of N-malonyltryptophan (MT) during leaf wilting of many species, but there is a significant number of plant species in which the appearance of MT did not occur. Plants of some species were able to synthesize also N-acetyltryptophan (AT). Excised tomato leaves incubated with D-amino acids (including D-Trp) transform them into malonyl-and acetyl-derivatives even without water deficit. However, MT which appeared during water deficit has been shown to contain L-Trp. Amino acid-1-amino-cyclopropane-1-carboxylic acid (ACC) is also malonylated during water deficit, but other L-amino acids were not malonylated. N-malonyl transferases specific for Trp and ACC have been found in several plants. The existence of N-malonyltransferase specific to L-Trp and appeared during water deficit in plants forming MT is supposed, but clear experimental proof has not been obtained yet. Plants can transform MT applied exogenously into Trp and further to indole-3-acetic acid (IAA). But no evidence has been appeared up to now that endogenous MT may be a source of IAA. It is unknown till now why it is necessary for plants of many species to malonylate only Trp during water deficit. How MT metabolized in animals and if it affects them is also unknown. The necessity to use molecular-genetic approaches for the elucidation of the physiological significance of MT formation during water deficit is underlined.

“…N-malonyl-D-tryptophan was identified in various seed plants, and 4-chloro-Dtryptophan was found in immature pea seeds. 88 D-Proline and derivatives were found in tree seeds and leaves. [89][90][91] D-Serine was found in tree leaves and grass.…”

Investigations on the occurrence and biochemical roles of free D‐amino acids and D‐amino acid‐containing peptides and proteins in living systems have increased in frequency and significance. Their occurrence and roles may vary substantially with progression from microbiotic to evermore advanced macrobiotic systems. We now understand many of the biosynthetic and regulatory pathways, which are outlined herein. Important uses for D‐amino acids in plants, invertebrates, and vertebrates are reviewed. Given its importance, a separate section on the occurrence and role of D‐amino acids in human disease is presented.

“…To sum up, the three studies show that abscisic acid does not play any direct inhibitory role in either dormancy release or germination, whereas cytokinin‐like substances appear to play a promotive role in both dormancy release and germination, and indole‐3‐acetic acid in germination only. A precursor of indole‐3‐acetic acid, N‐malonyl‐D‐tryptophan, which has been shown to occur in seeds and seedlings of some plant species, was absent from R. rugosa seeds and seedlings, and detectable as traces in wilted leaves only (Gamburg et al . 1991).…”
