Catecholamines (CAs) are neurotransmitters in mammals. They have been found in 44 plant families, but no essential metabolic function has been established for them. They are precursors of benzo[c]phenanthridine alkaloids, which are the active principal ingredients of many medicinal plant extracts. CAs have been implicated to have a possible protective role against insect predators, injuries, and nitrogen detoxification. They have been shown to promote plant tissue growth, somatic embryogenesis… Expand

ANIMAL NEUROTRANSMITTER SUBSTANCES IN PLANTS
TLDR
Dopamine, noradrenaline and adrenaline were shown to participate in intercellular regulation of ion permeability and photophosphorylation of chloroplasts, to play a role in adaptation of some plants to a changing environment. Expand
L-DOPA and Dopamine in Plant Metabolism
Nonprotein amino acids are widely distributed in the plants. They constitute a numerous group of secondary metabolites and represent a relevant reservoir of nitrogen and carbon. Among them,Expand
Evolutionary Considerations of Neurotransmitters in Microbial, Plant, and Animal Cells
TLDR
Non-nervous functions of neurotransmitters (rather “biomediators” on a cellular level) are considered in this review and compared with each other across different kingdoms. Expand
Tyrosine biosynthesis, metabolism, and catabolism in plants.
TLDR
The interspecies variations of plant Tyr pathway enzymes can now be used to enhance the production of Tyr and Tyr-derived compounds in plants and other synthetic biology platforms. Expand
Catecholamines are active plant-based drug compounds in Pisum sativum, Phaseolus vulgaris and Vicia faba Species
TLDR
The present study may provide a new avenue for preparation and estimation of L-DOPA and dopamine from plant sources and may be used for further analysis and therapeutic studies. Expand

TLDR
Non-nervous functions of neurotransmitters (rather "biomediators" on a cellular level) are considered in this review and ample consideration is given to similarities and differences that unite, as well as distinguish, taxonomical kingdoms. Expand
Expression of human dopamine receptor in potato (Solanum tuberosum) results in altered tuber carbon metabolism
TLDR
The data support the possible involvement of catecholamines in regulating plant carbon metabolism via cAMP signalling pathway and changes in the activities of key enzymes mediating sucrose to starch conversion and sucrose synthesis revealed changed content of both soluble sugars and starch. Expand
The catecholamine potentiates starch mobilization in transgenic potato tubers.
TLDR
The features indicate that catecholamines potentiate starch mobilization in potato plants in common with animal cells, and the decrease in tyrosine content in transgenic plants is also compensated by significant increase in chlorogenic acid synthesis thus potentially increasing the antioxidant capacity of transgenic tubers. Expand
Metabolite profiling driven analysis of Salsola species and their anti-acetylcholinesterase potential
TLDR
Roots of S. vermiculata and S. tetrandra were enriched in hydroxycinnamic acid conjugates, whereas flavonoids were more abundant in aerial parts with kaempferol derivatives as major Flavonoids in S.Tetrandra. Expand
The Fluorescence Methods to Study Neurotransmitters (Biomediators) in Plant Cells
TLDR
Fluorescence as a parameter for analysis of intracellular binding and localization of neurotransmitters also named biomediators as well as their receptors in plant cells has been estimated basing on several world publications and own experiments of the author. Expand

Function of serotonin in seeds of walnuts
TLDR
In plants serotonin may function as a hormone and as a protective agent against predation and a role for serotonin as a secondary plant product involved in ammonia detoxification in seeds of walnuts is proposed. Expand
Catecholamine Biosynthesis Dependent on the Dark in Betacyanin-forming Portulaca Callus.
TLDR
Betacyanin-forming callus of the red-flowering Portulaca grandiflora, Hook, is shown to contain dopamine, adrenaline, noradrenaline, and epinine, and the synthesis of dopamine via DOPA can be demonstrated by the use of inhibitors. Expand
Cytokinin antagonist activity of substituted phenethylamines in plant cell culture.
TLDR
It is proposed that the substituted phenethylamines may represent a class of chemicals that can be used as specific probes to further an understanding of cytokinin metabolism in plant tissues. Expand
Occurrence of L-DOPA and dopamine in plants and cell cultures ofMucuna pruriens and effects of 2,4-d and NaCl on these compounds
TLDR
Dopamine induction appears to be a specific metabolic effect of 2,4-d, whereas salt stress, as caused by the addition of NaCl, gives no induction of dopamine formation, whereas L-DOPA is released into the medium. Expand
Molecular Genetic Techniques Applied to the Analysis of Enzymes of Alkaloid Biosynthesis
TLDR
The use of indigenous plants in traditional medicine led to the discovery of alkaloids such as morphine, ajmalicine, quinine, scopolamine and a host of other structures which are still in use as pharmaceuticals today. Expand
Role of Catecholamines in Promotion of Flowering in a Short-Day Duckweed, Lemna paucicostata 6746.
TLDR
If catecholamines are provided to plants at 10(-4) molar level prior to transferring them to the short-day regime, they not only induce more floral primordia but also significantly improve flower development and sustain the flowers for a longer period. Expand
Growth stimulation by catecholamines in plant tissue/organ cultures.
TLDR
Dopamine inhibited IAA oxidase activity by 60 to 100% in crude enzyme extracts from tobacco roots and etiolated corn coleoptiles, but had no effect on peroxidase activity in the same extracts. Expand
Stimulation of ethylene production by catecholamines and phenylethylamine in potato cell suspension cultures
TLDR
The catecholamines and phenylethylamine were found to stimulate ethylene production in potato suspension cultures and the endogenous 1-aminocyclopropane-1-carboxylic acid levels were increased in parallel with the release of ethylene, suggesting that the observed effect probably occurs via regulation of aCC synthase. Expand
Dopamine Accumulation in Papaver somniferum Latex
TLDR
Organelles found in the 1000 x g fraction of latex taken from Papaver somniferum have been shown to accumulate dopamine to the exclusion of other catecholamines, and the relatively high, specificity of dopamine uptake, and insensitivity to inhibitors distinguish papaver latex organelle dopamine uptake fromcatecholamine uptake by mammalian chromaffin granules.

Hydroxycinnamoyl acid amides and aromatic amines in the inflorescences of some araceae species
TLDR
Hydroxycinnamoyl acid amides were found to be important components in the inflorescences of different Araceae species, and differences in the distribution of HCA's were noted between male and female flowers. Expand
