Technology offer : Varietal identification of coffee by molecular markers
The current strategy to discriminate coffee varieties by molecular markers are based on sequences mutations using elements such as SSR or SNP.
However, the discrimination efficiency of these markers regarding the differenciation between varieties or clones is limited, since a lot of datas must be generated, wich leads to additional costs.
IRD team suggests an innovative solution, simpler, more efficient and cheapest, using a single kind of markers: transposable elements, or active retrotransposons-LTR.
The marker Clem2 was identified for its simplicity to be detected all along the production cycle of coffee: it is transcripted independently from external factors and at all the stages of the plant development in all tissues or organes.
