Changes in DNA methylation are one of the best known mechanisms of epigenetic regulation of gene expression, which in the process of induced androgenesis is associated with reprogramming of haploid microspores development towards the formation of embryos, as a result of exposure of anthers in ears and then anthers culture in vitro to stress factors. The aim of the study was to test the hypothesis of whether the use of monochromatic light during induced androgenesis might be associated with epigenetic phenomena. The experiments were carried out on DH plants of spring barley (Hordeum vulgare L.) obtained by androgenesis modifi ed by monochromatic light: blue, green and red. A quantitative evaluation of the eff ect of light on the degree of DNA methylation was performed using RP-HPLC for the comparison of regenerants obtained under standard, control conditions (darkness) with those obtained with light usage. The diff erences in the amount of methylated cytidine in comparison to the control were: 0.40%, 0.16% and -0.55%, for blue, red and green light, respectively. The level of global genomic DNA methylation from control plants was in the range 21.32-21.52%. Methylation changes in response to monochromatic light used during callus formation in anthers culture, determined by RP-HPLC, are signifi cant although small.
