Abstract

Oxidative stress & an animal neurotransmitter synthesizing enzyme in wild growing myrtle leaves after GSM radiation exposure Aikaterina L, Stefi AL, Vassilacopoulou D, Margaritis LH, Christodoulakis NS. Oxidative stress and an animal neurotransmitter synthesizing enzyme in the leaves of wild growing myrtle after exposure to GSM radiation. Flora. 243:67-76. June 2018. doi.org Highlights • Mature myrtle plants were exposed to GSM radiation for 30 min, at 48 h intervals, for 50 days. • Secondary metabolite accumulation was observed in the exposed leaves. • Photosynthetic pigment content decreased in the exposed leaves. • The oxidative stress (ROS) increased in the exposed leaves. • Significant rise of the DDC level was recorded only in the exposed leaves. Abstract Mobile phones turned to be the most common form of public communication. Therefore, life on our planet continues wrapped in a "cloud" of non-ionizing radiations. Myrtus communis L. is an evergreen shrub, common in Mediterranean formations, exposed and adapted to two seasonally separated and qualitatively different environmental stresses. Thus, we considered it important to investigate the response of this tolerant species to emitted GSM non-ionizing radiations and compare it to already available data from thoroughly investigated plant species. Although the leaves of the exposed plants present unaffected tissue arrangement, their mesophyll cells accumulate large amounts of secondary metabolites, their photosynthetic pigments are dramatically reduced, the ROS counted are significantly increased and the presence of DDC, which cannot be detected in the leaves of the control plants, is recorded in high levels. The exposed leaves seem to experience a severe oxidative stress which probably induces DDC expression and the biosynthesis of the neurotransmitter dopamine, the activation of the shikimate pathway and, eventually, the accumulation of secondary metabolites. sciencedirect.com

Main findings

Mature myrtle plants exposed to GSM radiation showed increased ROS (oxidative stress), decreased photosynthetic pigments, and accumulation of secondary metabolites in exposed leaves. DDC was detected at high levels only in exposed leaves, while tissue arrangement was reported as unaffected.

Outcomes measured

  • secondary metabolite accumulation
  • photosynthetic pigment content
  • reactive oxygen species (ROS)/oxidative stress
  • DDC (animal neurotransmitter synthesizing enzyme) level/presence
  • leaf tissue arrangement/mesophyll cell changes

Limitations

  • Frequency and dosimetry (e.g., SAR/power density) not reported in the abstract
  • Sample size not reported
  • Exposure source described generally as GSM/mobile phone radiation without detailed setup
