Fig. 4From: Flax (Linum usitatissimum L.) response to non-optimal soil acidity and zinc deficiencyExpression differences in flax cultivars Norlin and Mogilevsky. Volcano plots illustrate the results of differential expression analysis between flax cultivars Norlin (tolerant) and Mogilevsky (sensitive) under control conditions (pH = 5.5, Zn+), Zn deficiency (pH = 5.5, Zn-), unfavorable pH (pH = 7.5, Zn+), and both stresses simultaneously (pH = 7.5, Zn-). Each point represents one gene. LogFC – binary logarithm of expression level fold change; LogFDR – decimal logarithm of the false discovery rate. Genes with expression fold change (increase or decrease) > 2 and FDR < 0.05 are marked with redBack to article page
