A TWO-FOR-ONE IN TOMATO NUTRITIONAL ENHANCEMENT

Control of multiple 'independent' pathwaysfor phytonutrient production in tomato by fruit-specific downregulation of a negativeregulator of photomorphogenesis.

Limiting downregulation of DET1 to fruit results

in increases in the three classes of natural

products shown, without negative effects onoverall plant growth and development.

Compounds are:LC, lycopene;

BC, -carotene;

NC, naringenin-chalcone; CGA, chlorogenic acid; QC, quercetin.

TOMATO FIBRE

Lycopene

Lyc-O-Mato® is an all-natural extract of red, ripe tomatoes, scientificallystandardized to contain 6% lycopene .

Lyc-O-Mato® is valued as a dietary supplement and functional foodingredient because it provides a full complement of tomato carotenoidsand other antioxidants to benefit good health. The synergy of the natural tomato Lycopen, phytoene, phytofluene, beta-carotene, phytosterols, andvitamin E results in enhanced activity and this means greater healthbenefits for you.

The tomatoes used are a high-Lycopen variety from plants that are grownin Israel without any genetic modification.

NUTRIGENOMICS

The use of genomics to investigate diet and gene

interactions involved in health or disease , often

used interchangeably with nutritional genomics.

This term implies that other portions of the

genome play a role in the genetic response to a

nutrient (even if researchers cannot assess the

total genome).
