Current Research

We are currently studying the biochemical factors that contribute to latex and rubber quality/quantity in Taraxacum kok-saghyz (Russian dandelion). This plant is currently considered to be a potential industrial crop for the production of natural rubber (polyisoprene) and latex rubber. We are generating proteome maps of latex-associated proteins to do comparative studies between the rubber producing Russian dandelion and the common dandelion, Taraxacum officinale. The proteome maps are complemented by RNA profiling with RNA sequences obtained from massive parallel sequencing (MPS).
