Urease-null soybean (eu3-a) under salt and copper stress: nitrogen metabolism, antioxidant defense, and arginine pathway genes
{{output}}
The eu3-a mutant exhibited greater tolerance to salt stress but increased sensitivity to copper stress, with distinct impacts on nitrogen metabolism, photosynthesis, and antioxidant responses. The eu3-a soybean mutant is urease-null, lacking all urease activit... ...
