Weeds like Palmer amaranth make farming harder and less profitable, and available herbicides are becoming less effective. For scientists to find solutions, they first need to know their enemy. A new study from the University of Illinois Urbana-Champaign and collaborating institutions reveals complete chromosome-level genomes for Palmer and two other Amaranthus species, smooth and redroot pigweed. The advancement represents a major leap in scientists鈥� understanding of the weeds鈥� biology, including their ability to detoxify common herbicides.
