Researchers discover protein that adjusts gene activity to match nutrient levels in roundworms
Transforming a fertilized egg into a fully functional adult is a complicated task. Cells must divide, move, and mature at specific times. Developmental genes control that process, turning on and off in a choreographed way.
However, the environment influences development. A team of researchers led by Cold Spring Harbor Laboratory Associate Professor Christopher Hammell reported on December 22, 2020, in the journal
Current Biology how gene activity matches nutrient levels.
They found a master switch developing worms use to pause growth when nutrients are scarce. When the environment improves, animals continue developing. The switch adjusts gene activity to match nutrient levels.
