Transcriptomic effects of irrigation with magnetized water on tomato (Solanum lycopersicum L.) during plant development

Altered growth and yield have been proven in numerous crops in response to irrigation with magnetized water but there is still a lack of studies reporting molecular-level changes underlying these physiological alterations of plants. This study is the first to reveal transcriptional changes occurred in seedlings, blooming plants, and plants with fully ripe berries in response to irrigation with magnetized water. A total of 21 differentially expressed genes (DEGs) identified in 3 phenological phases were mostly involved in metabolic processes (metabolisms of carbohydrate, glutathione, lipid, vitamin and cofactors, biosynthesis of phenolpropanoid and proline) and cellular processes (DNA synthesis, transcription, translation and their regulation). The processes were related to vegetative biomass, developing flowers and berries. Furthermore, expression intensities of DEGs encoding proteins participating in cell division and enlargement (xyloglucan endotransglucosylase/hydrolase, EXORDIUM like protein) and in regulating water flow and other transmembrane transport processes (B12D protein, aquaporins, and dehydrin) were affected. Overall design: For the control and magnetized water treatment, we used three biological replicates. mRNA-seq method was used for analyse the transcriptome profile for control and treated samples.
