英文摘要 | Carotenoids play crucial roles in structure and function of the photosynthetic apparatus of bacteria, algae, and higher plants. The formation of carotenoids from lycopene is catalyzed by the enzyme lycopene cyclase (LCY), which is structurally and functionally conserved in all organisms. A comparative genomic analysis regarding the LCY revealed that the higher plant (Arabidopsis thaliana) and the green alga (Ostreococcus sp. RCC809, Ostreococcus tauri, Ostreococcus lucimarinus, Micromonas sp. RCC299, Micromonas pusiua, Chlorella vulgaris, Volvox carteri, and Coccomyxa sp. C-169) possess two different LCY (beta- and epsilon-type). This indicated that an ancient gene duplication event must have occurred, which produced two classes of LCY in algae. However, some other green alga retained only one class of LCY, such as Haematococcus pluvialis (beta), Dunaliella salina (beta), Chlamydomonas reinhardtii (epsilon), and Chlorella sp. NC64A (epsilon), and the other gene copy was lost in these species. Furthermore, the similar LCY lost occurred in red alga (Cyanidioschyzon merolae) and Heterokontophyta (Phaeodactylum tricornutum and Thalassiosira pseudonana), which possess only the LCYB. In addition, the protein sequence of LCYB is highly similar to capsanthin-capsorubin synthase (CCS), which is another carotenogenic enzyme of plants. As a result, it is proposed that the CCS evolved from a duplicated LCYB. The discovery of two classes of LCY families in some algae suggests that carotenoid biosynthesis is differentially regulated in response to development and environmental stress in these algae, like members of LCY families are differentially regulated during development or stress in some higher plants.; Carotenoids play crucial roles in structure and function of the photosynthetic apparatus of bacteria, algae, and higher plants.
