A history of segregation ... food !
The queen of bees lives four years, she devotes her life to breeding, she is 2 to 3 times larger than working bees, who live only 45 days and spend their time foraging, Nevertheless ... the queen of the bees, at birth, is no different from the worker bees!
It is the alimentation that will make the difference:
- Future Worker: the larva receives royal jelly for two days, then she will feed herself honey all the rest of her life.
- Future Queen: the larva receives royal jelly all her life.
There is no genetic difference: the genes of these 2 larvae are the same.
Royal jelly, richer in nutrients than honey, contains a large number of substances: essential fatty acids, amino acids, vitamins, trace elements, etc., which promotes the expression of several genes
The nature offers us a good demonstration of the link between the nutrient and the gene:it is nutrigenomics!
What is it ?
The nutrigenomics is based on the technology of the DNA chip. Cells are first removed from the tissues of the animals of two batches (a control batch and a batch fed with the ration studied), the RNA extracted from these cells will then undergo fluorescent labeling and be hybridized on a DNA chip. The reading of the chip makes it possible to determine, by fluorescence reading, what proportion of the labeled RNA has interacted with each of the genes present on the chip. This is transcriptomics. In the end, it is possible to determine whether a gene (or a group of genes) is expressed more or less according to the ration received. These measurements are then validated by animal tests.
Suitable for ruminants
In order to improve our offer, Genial is looking for an epigenetic approach. Research on Nutrigenomics has highlighted the primordial role played by antioxidants (such as vitamin E and selenium) in maintaining an efficient immune system. Indeed, a low level of antioxidants in the blood causes disruption of the animal's immune system and inevitably leads to degradation of its health by reducing its growth rate, milk production and reproductive capacity.
