Strategies and methods for transformation to enhance carotenoids

P = phytoene PF = phytofluene -C = -carotene L = lycopene y-C = y-carotene p-C = p-carotene Lut = lutein Viola = violaxanthin Neo = neoxanthin d.p.b. days post breaker. 

All values are gg/g fresh weight. = includes all minor carotenoids. 

2 the availability of cloned genes encoding the enzymes of the pathway (see Section 13.5 and below)  

3 the availability of suitable promoters for expression of the transgene(s) in planta (see Section below)  

4 ideally, an understanding of the regulation of the pathway and the cellular compartmentation of the metabolites (see Section 13.5.5).
