Comparison of landrace and modern elite genotypes. A modern elite barley genotype (cv. KWS Irina) and two barley landraces contrasting in terms of Mn efficiency (Bere Unst Shetland and Bere Clho 8327; Fig. 2A, C) were cultivated under Mn-replete or Mn-deficient conditions in hydroponics. (A) Leaf Mn concentration (μg g–1 d. wt) in the youngest fully developed leaf. (B) Shoot biomass (g f. wt). (C) PSII efficiency (Fv/Fm) for the colour scale indicates the Fv/Fm values. (D) Manganese size-exclusion chromatograms of thylakoids isolated from KWS Irina (solid lines) and Bere Unst Shetland (dashed lines) grown under control (black lines) or Mn-deficient (red lines) conditions (representative chromatograms are shown out of three independent replicates per genotype/treatment). SC, supercomplexes; di, dimers; mono, monomers. In (A) and (B), the values are means ± s.e. (n = 3). Bars with the same letter are not significantly different (P ≥ 0.05).
