Rafflesiaceae is a family of parasitic plants found in east and southeast Asia, including Rafflesia arnoldii, the plant with the largest flower of all plants.
Rafflesiaceae was considered an unplaced family in the APG II system, while other authors placed it into the order Rafflesiales together with some other families of parasitic plants. More recent research places the family (in a restricted circumscription) in order Malpighiales (Barkman et al., 2004), and also does not consider the other families of the Rafflesiales order as related anymore (Nickrent et al., 2004).
The family sensu lato has traditionally included 9 genera, which have around 50 species altogether.
Astrocytes and synaptic plasticity Mon, 13 Oct 2008 00:00:00 -0400 (Rockefeller University Press) By mopping up excess neurotrophic factor from neuronal synapses, astrocytes may finely tune synaptic transmission to affect processes such as learning and memory, say Bergami et al. Their report is published in the Journal of Cell Biology. Body's anti-HIV drug explained Sun, 12 Oct 2008 00:00:00 -0400 (University of Southern California) Study in journal Nature reveals atomic structure of enzyme capable of repelling HIV virus, suggesting new approach for drug development. Pectin power Sun, 12 Oct 2008 00:00:00 -0400 (Norwich BioScience Institutes) Scientists from the UK's Institute of Food Research have found a new possible explanation for why people who eat more fruit and vegetables may gain protection against the spread of cancers.They have shown that a fragment released from pectin, found in all fruits and vegetables, binds to and is believed to inhibit galectin 3, a protein that plays a role in all stages of cancer progression.
