All roads lead to GUN1

Scientists have identified three different signals that indicate damage to chloroplasts -- the photosynthetic factories of plant cells that give plants their green color -- but little is known about how the signal gets passed on to the nucleus. Scientists at the Salk Institute for Biological Studies made a big step towards explaining how chloroplasts let a cell's nucleus know when things start to go wrong at the periphery so nuclear gene expression can be adjusted accordingly.
