COMMENTARY 
LITERATURE
agriculture
analysis
-
psy gene of tea cultivars is closely correlated to accumulation of carotenoids which are precursors of tea flavour volatiles, thus the expression strength of psy gene can be used as an indicator for screening quality of tea cultivars
biotechnology
nutrition
agriculture
Arabidopsis thaliana plants overexpressing Salicornia europea phytoene synthase gene show higher tolerance to salt stress than wild-type by increased photosynthesis efficiency and antioxidative capacity

nutrition
-
elevation of lycopene in tomato fruit by genetic manipulation of carotenoid biosynthesis using the fruit-specific expression of a bacterial phytoene synthase
nutrition
-
50fold increase in carotenoid levels in green embryos of Brassica napus after overexpression of bacterial phytoene synthase. Brassica and perhaps other oil seed crops may be used as commercial sources of carotenoids

engineering of a critical step in provitamin A biosynthesis in a non-photosynthetic, carotenoid-lacking plant tissue, important implications for long-term prospects of overcoming worldwide vitamin A deficiency
nutrition
bioengineering of astaxanthin biosynthesis in rice endosperm. Astaxanthin, a red-colored ketocarotenoid, has strong antioxidant activity and thus can benefit human health. However, astaxanthin is not produced in most higher plants. Introduction of a minimal set of four transgenes (sZmPSY1, sPaCrtI, sCrBKT, and sHpBHY, which encode the enzymes phytoene synthase, phytoene desaturase, beta-carotene ketolase, and beta-carotene hydroxylase, respectively) driven by rice endosperm-specific promoters establishes the carotenoid/ketocarotenoid/astaxanthin biosynthetic pathways in the endosperm of rice
nutrition
engineering of Yarrowia lipolytica for de novo production of the food and feed additive astaxanthin by fermentation. The astaxanthin-producing Yarrowia lipolytica shows great promise for employment in biological astaxanthin production. The genes for beta-carotene biosynthesis: bi-functional phytoene synthase/lycopene cyclase (crtYB) and phytoene desaturase (crtI) from Xanthophyllomyces dendrorhousa are introduced. The activities of 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMG1) and geranylgeranyl diphosphate synthase (GGS1/crtE) in the best producing strain are optimized. Downregulation of the competing squalene synthase SQS1 increases the beta-carotene titer. Then a beta-carotene ketolase (crtW) from Paracoccus sp. N81106 and hydroxylase (crtZ) from Pantoea ananatis are introduced to convert beta-carotene into astaxanthin. The constructed strain accumulates 10.4 mg/l of astaxanthin but also accumulates astaxanthin biosynthesis intermediates, 5.7 mg/l canthaxanthin, and 35.3 mg/l echinenone. The copy numbers of crtZ and crtW are optimized to obtain 3.5 mg/g dry cell weight (54.6 mg/l) of astaxanthin in a microtiter plate cultivation
nutrition
rice endosperm can be engineered to produce nutritionally important ketocarotenoids. The limited activity of endogenous beta-carotene hydroxylases causes a bottleneck in the extended ketocarotenoid pathway that must be overcome in order to maximize flux towards target ketocarotenoid molecules
