- Differential regulation of phenylalanine ammonia lyase activity and protein level by light in tomato seedlings (2008), Plant Physiol. Biochem., 46, 444-451.
Activating Compound
| Activating Compound | Comment | Organism | Structure |
|---|---|---|---|
| additional information | red light, acting via phytochrome, stimulates phenylalanine ammonia lyase activity in cotyledons and hypocotyls of tomato seedlings in a manner dependent on de novo synthesis of protein and nucleic acid. Photostimulation of PAL activity likely requires dephosphorylation by a type 2C protein phosphatase, thus inhibition of protein phosphatase activity blocks increase in PAL activity without affecting the increase in PAL protein levels | Solanum lycopersicum |
