| T1 |
0-136 |
Sentence |
denotes |
Protection of photosynthesis against ultraviolet-B radiation by carotenoids in transformants of the cyanobacterium synechococcus PCC7942 |
| T2 |
137-405 |
Sentence |
denotes |
The cyanobacterium Synechococcus PCC7942 was transformed with various carotenogenic genes, and the resulting transformants either accumulated higher amounts of beta-carotene and zeaxanthin or showed a shift in the carotenoid pattern toward the formation of zeaxanthin. |
| T3 |
406-614 |
Sentence |
denotes |
These transformants were exposed to ultraviolet-B (UV-B) radiation, and the degradation of phycobilins, the inactivation of photosynthetic oxygen evolution, and the activity of photosystem II were determined. |
| T4 |
615-709 |
Sentence |
denotes |
In the genetically modified cells, the influence on destruction of phycobilins was negligible. |
| T5 |
710-873 |
Sentence |
denotes |
However, protection of photosynthetic reactions against UV-B damage was observed and was dependent on the carotenoid concentrations in the different transformants. |
| T6 |
874-964 |
Sentence |
denotes |
Furthermore, it was shown that endogenous zeaxanthin is more effective than beta-carotene. |
| T7 |
965-1117 |
Sentence |
denotes |
Our results suggest that carotenoids exert their protective function as antioxidants to inactivate UV-B-induced radicals in the photosynthetic membrane. |
