Effects of abiotic stresses on the turnover of the D1 reaction centre II protein

Abstract
In the 1990's, evidence has accumulated that various unfavourable environmental conditions substantially affect the turnover of the D1 protein of reaction centre II, the psb A gene product. Biochemical, molecular and physiological studies in higher plants indicate that alterations of D1 protein turnover occur under drought, nutrition deficiency, heat, chemical stress, ozone fumigation as well as UV‐B and visible photo‐stresses. The behaviour of photosystem II under these various stress conditions indicates that the response of D1 protein turnover can be interpreted as a general adaptive response to environmental extremes.
