Effects of abscisic Acid treatment on the thermostability of the photosynthetic apparatus in barley chloroplasts.

abstract：:A circadian rhythm of O(2) evolution has been found in Euglena gracilis, Klebs strain Z. The rhythm persists for at least 5 days in constant dim light and temperature, but damps out in constant bright light. The phase of this rhythm can be shifted by a pulse of bright light and the period length is not changed over a ...
