“…Revealing the relationships between MF and plant responses is becoming more and more important as new evidence reveals the ability of plants to perceive and respond quickly to varying MF by altering their gene expression and phenotype. The recent implications of MF reversal with plant evolution opens new horizons not only in plant science but also to the whole biosphere, from the simplest organisms to human beings (Maffei, 2014).…”

“…The GMF has always been a natural feature of the Earth, so during evolution, all living organisms experienced its action. An increasing body of evidence shows that the GMF is able to influence many biological processes 1 . The GMF is not uniform and there are significant local differences in its magnitude and direction at the surface of the Earth.…”

“…Very little, or nothing, is known on the mechanisms of perception and responses of plants to magnetic fields, despite the plethora of papers published on this topic and recently reviewed 1 . Unlike the gravitational field, the GMF changed consistently during plant evolution thereby representing an important abiotic stress factor that has been recently considered a potential driving force eventually contributing to plant diversification and speciation 2 .…”

One of the most stimulating observations in plant evolution is a correlation between the occurrence of geomagnetic field (GMF) reversals (or excursions) and the moment of the radiation of Angiosperms. This led to the hypothesis that alterations in GMF polarity may play a role in plant evolution. Here, we describe a method to test this hypothesis by exposing Arabidopsis thaliana to artificially reversed GMF conditions. We used a three-axis magnetometer and the collected data were used to calculate the magnitude of the GMF. Three DC power supplies were connected to three Helmholtz coil pairs and were controlled by a computer to alter the GMF conditions. Plants grown in Petri plates were exposed to both normal and reversed GMF conditions. Sham exposure experiments were also performed. Exposed plants were photographed during the experiment and images were analyzed to calculate root length and leaf areas. Arabidopsis total RNA was extracted and Quantitative Real Time-PCR (qPCR) analyses were performed on gene expression of CRUCIFERIN 3 (CRU3), copper transport protein1 (COTP1), Redox Responsive Transcription Factor1 (RRTF1), Fe Superoxide Dismutase 1, (FSD1), Catalase3 (CAT3), Thylakoidal Ascorbate Peroxidase (TAPX), a cytosolic Ascorbate Peroxidase1 (APX1), and NADPH/respiratory burst oxidase protein D (RbohD). Four different reference genes were analysed to normalize the results of the qPCR. The best of the four genes was selected and the most stable gene for normalization was used. Our data show for the first time that reversing the GMF polarity using triaxial coils has significant effects on plant growth and gene expression. This supports the hypothesis that GMF reversal contributes to inducing changes in plant development that might justify a higher selective pressure, eventually leading to plant evolution.

A b s t r a c tIn spite of high biological potential demonstrated in field trials, many potato cultivars did not show a full productivity at a large-scale production that can be caused by both external (cultivation conditions) and internal (quality and adaptive potential of seed material) factors. To date, a number of seed-stimulating technologies based on the use of the laser, ultrasound, cold plasma, magnetic and electromagnetic fields have been developed. A pre-planting treatment of seeds with low-frequency pulse electric field (LF-PEF) was proved to have a positive effect on the seed qualities and productivity of some agricultural crops including lettuce, parsley, red beet, and carrot. However, the mechanisms of this effect still remain unclear. In this study we assessed the response of 13 different potato varieties to the LF-PEF treatment on several morphometric traits. The study was carried out at three geographical points: Tuberosum Technologies LLC (Saskachewan, Canada, 2009, 11 varieties of different reproductions used for the baby potato production), the field of All-Russian Research Institute of Phytopathology (ARRIP, Moscow Province, 2011; variety Saturna), and Ozery LLC (Moscow Province, 2012; variety Lady Clair). For each variety, 20 kg (Tuberosum Technologies), 200 kg (ARRIP), and 2 tons (Ozery) of seed potato were treated 3-5 days prior the planting using an experimental LF-PEF generator developed by the Intelpro LLC (Russia). Generated electric field was characterized by a broadband frequency range and had the following parameters: carrier frequency 16±10 kHz, repetition rate of the modulating pulse pattern 200 Hz, generated field intensity 20 kV/m. According to the earlier optimized mode, the seed potato was exposed to LF-PEF for 24 h. Protective treatments with fungicides were the same for both treated and untreated plants used as control. Plant height, number of stems per plant, number of leaves per stem, fresh weight of above-ground parts, and the number and total weight of tubers per plant were measured at flowering; each variant (control or treatment) included 10 plants in four repetitions. For the majority of the studied varieties, the LF-PEF treatment did not significantly influence on plant height, number of leaves per stem, and fresh weight of above-ground parts of plants. At the same time, the number of stems per plant and the number and weight of tubers per a plant increased; the revealed changes were reliable and significant for the majority of varieties (80-95 %). The variety-averaged increase in the number of stems and the number and weight of tubers per plant made 27.0, 28.3 и 31.1 %, respectively, as compared to the control. The obtained data agree with the results of our earlier large-scale trials of the LF-PEF technology arranged in different regions of Russia.
