A dominant mutation in β-AMYLASE1 disrupts nighttime control of starch degradation in Arabidopsis leaves (Plant Physiol)

Plants use starch in leaf chloroplasts to fuel their growth and metabolism during the night. In Arabidopsis, nighttime starch degradation is tightly regulated; the degradation rate is linear and adjusts to both the availability of starch and length of night, so that most but not all the starch is used…
