The FEBS Journal, EarlyView.Vitamin B6 is a critical molecule for plant metabolism and development. Rsr4‐1, a loss‐of‐function mutant in a vitamin B6 biosynthesis gene, has a distinct short root phenotype. Here we describe five novel suppressor mutants with an rsr4‐1 background that have normalized root growth and distinct phenotypic and molecular characteristics, representing a ...
