One-way light, flexible electricity and plant networks in this week's news

Plant's road map revealed
When plant pathogens attack, they go for highly connected “hub” proteins, a new analysis reveals. The research draws from an enormous new map of protein interactions in Arabidopsis, the lab rat of the plant world. Scientists from the Arabidopsis Interactome Mapping Consortium identified more than 6,000 interactions among 2,700 Arabidopsis proteins and mapped them as a network, revealing both protein communities and the streets connecting them. Thus far the effort, presented in two papers in the July 29 Science, maps about one third of the little plant’s proteins,  suggesting more will be uncovered about  plant defense and offense.  —Rachel Ehrenberg
