Excessive accumulation of the auxin precursor IAM hampers embry devepment in Arabidopsis

Members of the Pollmann Lab recently demonstrated that alterations of endogenous auxin levels have profound impacts on embryo- and seed size, which represents an agriculturally important trait. The accumulation of the IAA precursor IAM in the double mutant ami1 rty exerts a growth inhibiting effect and compromises embryo development.
