摘要：

Abstract— Photoreactivating enzyme (PRE) activity was measured in hypocotyls of Phaseolus vulgaris L. seedlings using a radioimmunoassay for thymine dimers. In dark‐grown seedlings a five‐fold increase in PRE activity was observed after 6 h of irradiation with blue or far‐red light. Short time irradiations with red light were also effective. Reversibility of this red‐light‐effect by a subsequent short term irradiation with far‐red light and also the high effectiveness of continuous far‐red light indicate that PRE activity is under phytochrome control. This observation points to PRE induction via gene activation. Copyright © 1990, Wiley Blackwell. All rights reserved
