MTR_8G066260 — Medicago truncatula

Summary

MTR_8G066260 (MtAP1) encodes a MADS-box transcription factor with RNA polymerase II-specific DNA-binding activity, chromatin binding, and transcriptional co-regulator functions. In barrel medic, MtAP1 is associated with floral whorl development, regulation of double fertilization, release of seed from dormancy, and abscisic acid breakdown. The gene is linked to numerous traits including fruit shattering, inflorescence branching, floral organ size, seed color, leaf morphology, and vegetative-to-reproductive phase transition. It localizes to the nucleus, cytoplasm, plastid, and plasmodesmata. Studies of related genes in other species connect the family to floral meristem identity, fruit development, petal and stamen formation, seed yield, pod shatter resistance, and temperature-responsive flowering.
