AP1 — Glycine max

Summary

GmAP1 (GLYMA_08G269800V4) on soybean chromosome 8 encodes a MADS-box transcription factor with RNA polymerase II-specific DNA-binding and transcriptional co-regulator activities. The gene is associated with floral whorl development, regulation of double fertilization, release of seed from dormancy, and miRNA processing. It has been linked to numerous agronomic traits including fruit shattering, seed color, seed coat morphology, floral organ size and number, petal number, leaf margin morphology, stem thickness, branch number, net photosynthetic rate, and vegetative-to-reproductive phase transition. The gene is also connected to floral meristem identity, fruit development, inflorescence determinacy, and secondary growth. Related genes in other species are linked to petal and stamen identity, seed yield, leaf longevity, and temperature-responsive flowering.
