Functional characterization of various algal carotenoid ketolases reveals that ketolating zeaxanthin efficiently is essential for high production of astaxanthin in transgenic Arabidopsis [PDF]

open access: yes, 2011
Extending the carotenoid pathway to astaxanthin in plants is of scientific and industrial interest. However, expression of a microbial beta-carotene ketolase (BKT) that catalyses the formation of ketocarotenoids in transgenic plants typically results in ...

Dietary Carotenoids and Cognitive Decline: A Longitudinal Study Among Chinese Middle-Aged and Older Adults. [PDF]

open access: yesHealth Care Sci
Higher intake of dietary carotenoids was associated with slower cognitive decline. The strongest protective association was observed for moderate carotenoid intake. Total carotenoid intake exhibited a non‐linear association with cognitive decline. ABSTRACT Background This study examined the association between dietary intakes of total and specific ...

Identification of alleles of carotenoid pathway genes important for zeaxanthin accumulation in potato tubers [PDF]

open access: yes, 2010
We have investigated the genetics and molecular biology of orange flesh colour in potato (Solanum tuberosum L.). To this end the natural diversity in three genes of the carotenoid pathway was assessed by SNP analyses.
