The present study reports evidence of the pleiotropic effects caused by the insertion of the rat glucocorticoid receptor (GR) into the genome of Nicotiana langsdorffii. Transgenic N. langsdorffii-GR plants and the wild-type genotypes were analysed for their phenotypic and physiological characteristics. The integration of the GR gene affected flowering, growth habit, leaf morphology and stomatal pattern. Furthermore, GR plants showed an increased tolerance to heavy metal, drought and heat stress as evidenced by electrolyte leakage and by cell dedifferentiation and differentiation capability after recovery from stress treatments. We also monitored the establishment of the beneficial symbiosis between transgenic plants and the mycorrhizal fungus Funneliformis mosseae whose presymbiotic growth was significantly reduced by root exudates of N. langsdorffii-GR plants. The observed pleiotropic responses of transgenic plants may be a consequence of the hormonal imbalance, putatively due to the interaction of the GR receptor with the host genetic background. Our findings suggest that N. langsdorffii-GR plants can be used as a functional model system for the study of plant responses to a series of environmental stimuli.

Background: Affecting more women than men, fibromyalgia syndrome (FMS) is a rheumatic disorder characterized by chronic, diffuse and widespread musculoskeletal pain, and its pathogenesis is still unknown. Among the recommended treatments, acupuncture (for its analgesic effects) is an effective option for reducing the pain sensitivity and improving quality of life. Therefore, this study aimed to investigate whether acupuncture at tender points could effectively manage FMS. Methods: Eight female patients, with a previous diagnosis of fibromyalgia, underwent an initial assessment involving pressure algometer measurements for pain tolerance and questionnaires [Fibromyalgia Impact Questionnaire (FIQ), Heath Assessment Questionnaire (HAQ), Beck Depression Inventory (BDI), and Beck Anxiety Inventory (BAI)], followed by treatment. Over a 2-month period, acupuncture was performed once per week at five tender points, located bilaterally at the occipital bone, trapezius, rhomboid, upper chest and lateral epicondyle. At the end of treatment, the participants underwent a reassessment for a final review of the applied methods. Results: We observed a reduction in the pain threshold and sensitivity and improvement in the areas of anxiety and depression and quality of life, which were demonstrated using the FIQ, BDI and BAI but not the HAQ.
