A large effect genetic trade-off is caused by a single mutation in CBF2
Understanding the genetic basis of local adaptation of a species is an important but thorny problem. Now that whole genomes are readily characterized, it’s not hard to see lots of differences between populations, but pulling meaning and demonstrating functional consequences out of those differences…

Unraveling cold tolerance in maize
Li et al. discover a cold-tolerance allele that was not selected during maize domestication.
Background: Cold stress is an important environmental factor that limits plant growth, development, and geographical distribution. Maize originated in Mexico and is sensitive to low temperatures. Cold stress…
