“…Considering that exogenous dopamine inhibits root elongation in soybean seedlings (Guidotti, Gomes, Siqueira-Soares, Soares and Ferrarese-Filho, 2013), the shortening of roots due to increased hardness may be causally related to the dopamine levels. Alternatively, high dopamine may ameliorate stress imposed by ROS by acting as an antioxidant, similar to that observed with dopamine-treated soybean and apple roots (Gomes et al, 2014; Jiao et al, 2019).…”

Plant roots encounter coarse environs right after emergence from the seeds. Little is known about metabolic changes enabling roots to overcome the soil impedance. Tomato seedlings grown vertically or horizontally, at increasing hardness, exhibited lateral roots proliferation, shorter hypocotyls, and primary roots. In primary root tips, hardness-elicited loss of amyloplasts staining; induced ROS and NO accumulation. The levels of IBA, zeatin, jasmonates, and salicylic acids markedly differed in roots and shoots exposed to increasing hardness. Hardness lowered IAA and elevated ABA levels, while increased ethylene emission was confined to horizontally-impeded seedlings. The trajectories of metabolomic shifts distinctly differed between vertically/horizontally-impeded roots/shoots. In horizontal roots, amino acids were the major affected group, while in vertical roots, sugars were the major group. Commonly affected metabolites in roots and shoots, trehalose, dopamine, caffeoylquinic acid, and suberic acid, hallmarked the signature for hardness. Increasing hardness lowered SnRK1a expression in roots/shoots implying regulation of metabolic homeostasis by the SnRK1 signalling module. Our data suggest that though hardness is a common denominator, roots sense the horizontal/vertical orientation and correspondingly modulate metabolite profiles.Significance statementWe show that the tomato roots sense the magnitude of hardness as well as the horizontal and vertical orientation. The hardness divergently modulates the phytohormone and metabolite levels in roots and shoots. The trajectory of the metabolic shift in vertically-grown seedling distinctly differs from horizontally-grown seedlings. ABA and trehalose were the hallmark of hardness stress and may influence metabolic alteration via the SNRK signalling pathway.

“…Dopamine-induced elevation in superoxide dismutase activity and subsequent reduction in ROS levels and lipid peroxidation has been reported in soybean roots. 109 The antioxidative role of this biomolecule has been reported. 110 The allelopathic effect of dopamine has also been observed to be growth inhibitory for soybean roots.…”

Neurotransmitters (NTs) such as acetylcholine, biogenic amines (dopamine, noradrenaline, adrenaline, histamine), indoleamines [(melatonin (MEL) & serotonin (SER)] have been found not only in mammalians, but also in diverse living organisms-microorganisms to plants. These NTs have emerged as potential signaling molecules in the last decade of investigations in various plant systems. NTs have been found to play important roles in plant life including-organogenesis, flowering, ion permeability, photosynthesis, circadian rhythm, reproduction, fruit ripening, photomorphogenesis, adaptation to environmental changes. This review will provide an overview of recent advancements on the physiological and molecular mechanism of NTs in plants. Moreover, molecular crosstalk of SER and MEL with various biomolecules is also discussed. The study of these NTs may serve as new understanding of the mechanisms of signal transmission and cell sensing in plants subjected to various environmental stimulus.

“…Also, in Rosaceae family, recent research has found that exogenous dopamine could regulate apple's drought resistance and salt tolerance by stomatal behavior (Li et al, 2015;Gao et al, 2020), as well as alleviate the drought-induced damages, replenishing of K, N, P, S, Cu and other trace elements (Li et al, 2015;Gao et al, 2020). Research about soybean even demonstrated that dopamine can affect the activity of antioxidant enzymes and the content of reactive oxygen species (ROS) in roots, thus enhancing the antioxidant activity in plants (Gomes et al, 2014).…”

Hormones play a crucial role both in plants and animals. As we all known, hormones work through specific receptors in different organisms. Therefore, the hormone interaction between plant and animal is an interesting question worth discussing. Recently, food safety has become a common topic concerned by consumers. A widely discussed rumor such as "Fruit bulking agent is some human reproductive hormones" leads us to consider whether animal hormones did regulate plant growth. Based on the large amount of previous research, we demonstrated that animal hormones did affect plant, such as steroid hormones for livestock feed could regulate physiological processes in plant including flowering, senescence and stress resistance after excreted into the environment. Here, we summarize the previous studies and systematically discuss the effects of animal hormones on plant growth and development.
