Abstract: | Background Natural rubber is a biopolymer with exceptional qualities that cannot be completely replaced using synthetic alternatives.
Although several key enzymes in the rubber biosynthetic pathway have been isolated, mainly from plants such as Hevea brasiliensis, Ficus spec. and the desert shrub Parthenium argentatum, there have been no in planta functional studies, e.g. by RNA interference, due to the absence of efficient and reproducible protocols for genetic engineering.
In contrast, the Russian dandelion Taraxacum koksaghyz, which has long been considered as a potential alternative source of low-cost natural rubber, has a rapid life cycle and
can be genetically transformed using a simple and reliable procedure. However, there is very little molecular data available
for either the rubber polymer itself or its biosynthesis in T. koksaghyz. |
