'The most charismatic and strange of all flowering plants'


‘The most charismatic and strange of all flowering plants’
When it comes to parasites, these plants are the stuff of nightmares.
Called Rafflesiaceae, they have no roots, stems, or leaves of their own. For most of their lifespan they are invisible, living only as a small necklace of cells inside the woody vines of their host. Then, without warning like the creature in the movie “Alien” they burst out to bloom some of the largest flowers in the world. Their pungent smell of rotting meat or fruit attracts the carrion flies that help pollinate these plants, allowing them to seed and spread to another unsuspecting host, restarting the whole cycle. ....

On January 22 in
Current Biology, a team of Harvard-led researchers presented the most complete genome yet assembled of one of the major Rafflesiaceae lineages,
Sapria himalayana.
The species is found in Southeast Asia and its mottled red and white flower is about the size of a dinner plate. (It s more famous cousin,
Rafflesia arnoldii, produces blossoms nearly three feet in diameter, the largest in the world.)
The genetic analysis revealed an astonishing degree of gene loss and surprising amounts of gene theft from its ancient and modern hosts. These findings bring unique perspectives into the number and kind of genes it takes to be an endoparasite (an organism that is completely dependent on its host for all nutrients), along with offering new insights in ....
