Sensitivity to Humidity and Temperature in Darkness of the Photoinduction ofS-Adenosyl-L-Methionine Decarboxylase Activity in Leaves ofPharbitis nil

摘要

The activity ofS-adenosyl-L-methionine decarboxylase (SAMD) in leaves ofPharbitis nilincreased maximally at“lights-on”after growth in darkness for 16 h at 21 to 25°C and 30%to 40%relative humidity. Under other condition, less SAMD activity was induced. The photoinduction of SAMD was also observed in leaves of many other plant spe
