Planaria Matrix

April 28th, 2012

A great image from PLoS Computanional Biology: ‘ The correct regeneration of complex morphology after amputation in planaria requires precise coordination of global patterning information and individual stem cell activity. This image illustrates the algorithmic information that is processed by cells and tissues to restore missing structures.’ See Lobo and Beane (e1002281)

It’s a bit wild, wet and cold here at the moment … but skies are big.

Rust in the limelight

April 20th, 2012

Image by Benjamin Petre and Stephane Hacquard on the cover of the March 2012 issue of Molecular Plant Microbe Interactions. Congrats to Steph, David, Seb and coauthors for their paper: ‘A Comprehensive Analysis of Genes Encoding Small Secreted Proteins Identifies Candidate Effectors in Melampsora larici-populina (Poplar Leaf Rust)‘.

Uredinia formed by the rust fungus Melampsora larici-populina 7 days after inoculation on susceptible poplar leaves (severe and weak infection are pictured above and below the midrib, respectively). The panels below show immunofluorescence localization of small secreted proteins at the periphery of distinct infection structures in poplar leaves.
