[reposted from h-net]CFP – The Spanish Urban Space in the 20th and 21st Centuries

Transitions: Journal of Franco-Iberian Studies seeks papers for a special number Navigating through the Spanish Urban Space in the 20th and 21st Centuries, to be devoted to the representation of the Spanish Urban Space in the 20th and 21st centuries. This volume will function as a mirror of our last issue constituted on the Parisian Banlieue. Papers should address perceptions, representations, or negotiations of the city in Spain through literature, film and/or art.

Parasitic Plants Rafflesia cantleyi Steal Genes from Their Hosts!!!

Analysis of these genes shows that their functions range from respiration to metabolism, and that some of them have even replaced the parasites own gene activity.

Vertical gene transfer occurs between parents and their offspring, while horizontal gene transfer is the movement of genes between two different organisms. Bacteria use horizontal gene transfer to exchange resistance to antibiotics. Recent studies have shown that plants can also use horizontal gene transfer, especially parasitic plants and their hosts due to their intimate physical connections.
