Expression

EC Number Organism Comment Expression
2.6.1.2 Triticum aestivum nitrogen deprivation results in reduced transcript levels for AlaAT. The effect is more pronounced for AlaAT1 down
2.6.1.2 Triticum aestivum hypoxia induces transcript levels for AlaAT1 but not AlaAT2. Hypoxia induces AlaAT1 earlier in roots than in shoots up
