| Kinetic of Lipoquinone and Pigment Synthesis during Red Light-Induced Thylakoid Formation in Etiolated Barley Seedlings  | | | | Abstract
| Red light induces in etioplasts of dark-grown barley seedlings (H ordeum vulgare L.) parallel to the formation of chlorophyll an increased synthesis of carotenoids, lipophilic benzoquinones and of vitamin Kt . 1. Among the carotenoids red light initiates an enhanced synthesis of /2-carotene, lutein, violaxanthine and neoxanthine whereas the pools of zeaxanthine and antheraxanthine are decreased. 2. The formation of plastoquinone-9, vitamin Kj and a-tocoquinone is more enhanced than that of a-tocopherol. 3. The red light-induced changes of carotenoid and lipoquinone metabolism are similar in a qualitative sense to those obtained under continuous far-red, white or blue light. 4. In contrast to blue light, red light induces in the first hours of illumination a lower rate of chlorophyll and vitamin Kt formation. There are also differences in the ratios of the individual pigments and lipoquinones throughout the greening period. | | | |
