Possible Interaction: Serine and Kinetin

“l-Serine, which promotes dark senescence, does not significantly modify the dark ATP level, but both arginine and kinetin , which antagonize the action of serine on senescence, greatly lower the ATP level below that on serine alone.”

“ l-Serine , which actively promotes senescence in the leaf, has only a very slight effect on the chloroplasts, and kinetin antagonizes it.”

“Since the action of serine was found to be more powerful in presence of kinetin than alone, the effects of other amino acids have been restudied in presence of kinetin.”

“Firstly, l-serine specifically enhances senescence, especially in presence of kinetin.”
