Abstract

Caffeine biosynthesis involves sequential methylation of the purine ring by the transfer of methyl group from the methyl donor S-adenosyl methionine. Genes that code for the individual methyl transferase have a high degree of sequence homology. To achieve decaffeination by genetic engineering of coffee, the effect and efficiency of different post-transcriptional gene silencing (PTGS) constructs were evaluated. Sense, antisense and invert repeat constructs were developed using a 339 bp fragment from the conserved region of the coffee Nmethyltransferase genes involved in caffeine biosynthesis.
