Involved in the promotion of leaf and floral meristem fate and determinacy (PubMed:23136374, PubMed:23151794). Promotes normal stipule growth and development (PubMed:23136374, PubMed:10948249, PubMed:19488780). Down-regulates UNI expression in primordia of leaves and secondary inflorescences, and thereby controls their sizes and/or structures (PubMed:23151794). Involved in the coordination of the symbiotic nodule developmental program (PubMed:16043431). Necessary for the robust maintenance of nodule identity throughout the nodule developmental program (PubMed:16043431). Altered morphology of stipules (PubMed:23136374, PubMed:10948249, PubMed:19488780). Altered morphology of flowers (PubMed:23136374). Production of abnormal nodules that develop roots from the apical part of the nodule (PubMed:16043431).
