Other claims from this paper (12)
- Association Laanaceur leaves accumulated five times more lysine than other varieties under both nitrogen regimes.
- Association Barley adaptation to limiting nitrogen showed a genotype by environment interaction.
- Intervention effect Nitrogen limitation reduced biomass in all barley genotypes.
- Intervention effect Nitrogen limitation increased carbon concentration in all barley genotypes.
- Intervention effect Nitrogen limitation increased allocation to barley roots.
- Association Leaf nitrogen use efficiency positively correlated with plant nitrogen uptake efficiency.
- Association Leaf nitrogen use efficiency positively correlated with root nitrogen use efficiency.
- Observation The authors classified barley genotypes as high, moderate or low in tolerance to nitrogen limitation.
- Intervention effect Nitrogen supply affected signaling, ionic transport, immunity and stress-response functions.
- Intervention effect HvNRT2.10 was upregulated under low nitrogen in three barley genotypes.
- Observation Lysine biosynthesis and catabolism enzyme genes were upregulated in Laanaceur.
- Mechanism The authors infer that upregulated lysine metabolic genes likely explain Laanaceur lysine accumulation.
