AINTEGUMENTA-LIKE6 Can Functionally Replace AINTEGUMENTA but Alters Arabidopsis Flower Development When Misexpressed at High Levels

Key message Expression differences underlie the functional differences between two related transcription factors: AINTEGUMENTA and AINTEGUMENTA-LIKE6. Ectopic expression of AINTEGUMENTA-LIKE6 at high levels alters floral organ initiation, growth and identity specification.
