Effect of near UV on ethylene formation of Chlorella

Abstract

In the present experiment, we analyzed the effect of near UV on the growth of Chlorella ellipsoidea(IAM-27). As a resullt, near UV inhibited the growth and physiological activities.
Ethylene, a kind of plant hormons, is known to regulate the growth of plants. So far, ethylene formation by Chlorella has not been reported. Herein, we detected the activities of ACC synthetase/ACC oxidase and the levels of ACC/ethylene. This evidence shows that Chlorella has the system of ethylene formation. Furthermore, these enzymes and substances were regulated to be inhibited by near UV.
