Altering root system architecture in barley without impacting above-ground traits
Roots are important for acquiring water and nutrients from the soil; however root system architecture is poorly understood in cereal crops. Here Aldiss et al. used CRISPR/Cas9 to generate barley mutants in the auxin transporter PIN-FORMED2 (PIN2). Seedlings were grown in chambers and after four days the chambers were rotated by 90o. Whilst the roots […]
