“…To our knowledge, this study first reports the involvement of genome-wide DNA methylation remodeling in the regulation of plant response due to photoperiodic variation in buckwheat. These results are in accordance with various studies in different species, where the genotypespecific shift in DNA methylation pattern under different photoperiodic conditions was reported (Brutch et al, 2019;Guzy-Wrobelska et al, 2013;Takeno, 2010). Takeno (2010) reported that DNA methylation pattern in Perilla frutescens and Pharbitis nil altered with the change in photoperiodic treatment.…”

Tartary buckwheat, known for its rich source of health beneficial secondary metabolites, is cultivated in many areas of the world. Among different environmental factors, photoperiod strongly influence its growth, flowering time, and ultimately the yield. In this context, epigenetics could contribute significantly in the regulation of plant response against changing environment. Therefore, with the aim to study the involvement of DNA methylation in photoperiod mediated plant response, genome-wide DNA methylation analysis was performed in two accessions (A1 and A2) of Tartary buckwheat using three photoperiodic treatments, i.e., 10-hr light/day (T1), 12-hr light/day (T2), and 14-hr light/day (T3). Flowering time and plant fresh weight data revealed that accessions A1 and A2 prefer T1 and T2 treatments, respectively. Total DNA methylation ratio increased with the increase in photoperiod in accession A1 but decreased under same conditions in accession A2. Full methylation increased significantly while intensive decrease in hemimethylation was noted from T2 to T3 in A1, whereas full methylation strongly increased and hemimethylation strongly decreased from T1 to T2 in A2. Overall, the DNA methylation events appeared more frequently than demethylation events. This study reports for the first time an accession-/genotype specific pattern of shift in the DNA methylation under different photoperiodic treatments that will pave the way toward identification of specific genes involved in the regulation of plant response against photoperiodic stress.

“…Em avaliações de linhaça e linho realizadas em diferentes países e latitudes, verificou-se que a sensibilidade fotoperiódica de linhaça é bastante variável em função de características ambientais como latitude e fotoperíodo do local de cultivo e de características intrínsecas à genética da planta (BRUTCH et al, 2020). Portanto, o grau de fotossensibilidade original da espécie pode ter sido alterado via a domesticação das plantas, e pelos programas de melhoramento genético ao longo dos anos nos diferentes locais de cultivo.…”

“…This period coincides with the so-called light stage, during which flax plants express sensitivity to the photoperiod. Cultivated flax is a long-day plant [13], but numerous differences in the degree of response to photoperiod reduction were found among fiber flax and linseed [14,15].…”

Weather has significant impact on plant growth and development. It is important to analyze the influence of changing climate conditions on the expression of plant agronomic characters. Two flax varieties were grown from 1987 to 2018 in the Northwest of Russia. Weather conditions and their influence on flax agronomic characters were analyzed using the variance and correlations analyses. Significant influence of conditions of a particular year on the manifestation of all evaluated characters was revealed. Starting from June, high temperatures accelerate plant development at all stages. Prolongation of the germination-flowering period is most important for improving fiber productivity, while fast ripening in hot weather after flowering is preferable for the formation of high-quality fiber. Such data give a possibility to predict the yield amount and quality. The use of weather conditions data also makes possible a comparison of the results obtained in different years. The suggested method of classifying meteorological conditions of a year can be used in other genebanks for systematizing and analyzing the results of crop evaluation in the field. The correlation analysis revealed 3 correlated pleiades, namely (1) of productivity, (2) of fiber quality and yield, and (3) of the growing season phase durations, the sums of active temperatures and precipitation during each period. The great influence of growing conditions on the economically valuable traits indicates the necessity of searching for genotypes with stable character manifestations for breeding new varieties with stable yields and good fiber quality.
