Abstract excerpt
Achieving optimal flowering time is a pivotal factor in precision plant breeding. Here, in maize, we characterized an EMS-induced additive delayed-flowering mutant, edf1. edf1 and its heterozygotes are late-flowering under both long- and short-day photoperiods in the field, and harbor a splice-donor mutation in ALTERED PHLOEM DEVELOPMENT (APL). This mutation leads to the accumulation of the minor APL-β...
