Fig. 6From: Short-term inhibition of glutamine synthetase leads to reprogramming of amino acid and lipid metabolism in roots and leaves of tea plant (Camellia sinensis L.)Total content of free ammonium (NH4+) in control (CK) and methionine sulfoximine (MSX)-treated tea plants. CK-R/CK-L, roots (R) or leaves (L) of tea plants cultured in nutrient solution without MSX; MSX-R/MSX-L, roots (R) or leaves (L) of tea plants subjected to MSX treatment. Asterisks indicate statistically significant differences between MSX and CK groups (**P < 0.01) detected using the Student’s t-testBack to article page
