New research by University of Utah biologists uncovers how aspen trees 'remember' past drought in their leaves. Concentrations of chemical compounds that protect aspens from insects and pathogens rise and fall in the years after exposure to drought.
And to truly understand the connection between genetic variants and disease and complex traits requires understanding how gene expression and splicing are controlled.
And to do that, you need a lot of data, more than previous studies have used, finds a recent study published in Science.
