摘要：

Carotenoids play key roles in photosynthesis and photoprotection. Few multicellular plants produce the ketocarotenoid astaxanthin, a strong antioxidant; however, Arabidopsis thaliana lines overexpressing the Chlamydomonas reinhardtii β-carotene ketolase (CrBKT) accumulated high amounts of astaxanthin in the leaves. In this study, we investigated the changed regulation of key metabolic pathways and the tolerance of the engineered plants to biotic and abiotic stresses resulting from the heterologous expression of CrBKT. Transcriptome analysis id...
