ALMT1 enhances root growth of barley on acid soils. (A) Seedlings of the various T2 homozygous ALMT1-expressing lines of barley (lines 4-6 denoted by L4-L6), WT barley, and the near-isogenic wheat lines ET8/ES8 were grown on an unamended acid soil obtained from Chiltern, Australia, and the same soil neutralized with CaCO3. After 4 days, the longest root of each seedling was measured and root growth over 4 days calculated [error bars denote ±SEM (n = 6-8), and the least significant difference (LSD) at P < 0.05 is shown for the interactions of root length with treatments and genotypes]. (B) Seedlings of the various T2 homozygous ALMT1-expressing lines of barley (lines 4-6 denoted by L4-L6), WT barley (WT), and the near-isogenic wheat lines ET8/ES8 were grown on an acid soil obtained from Tohoku, Japan, and a neutral medium consisting of fertilized peat moss. After 4 days, the longest root of each seedling was measured [error bars denote ±SEM (n = 6), and the LSD at P < 0.05 is shown for the interactions of root length with treatments and genotypes].
