PCF4 — Medicago truncatula

Summary

MtPCF4 (MTR_8G463380) on barrel medic chromosome 8 encodes a TCP transcription factor with DNA-binding and transcription activator activity, and is also annotated with pinoresinol reductase activity. The gene is associated with the regulation of miRNA processing, proximal/distal pattern formation, specification of symmetry, and adaxial/abaxial axis specification. It is linked to the upregulation of flavonol and proanthocyanidin biosynthesis, lignan anabolism, and the downregulation of innate immune response. MtPCF4 has been connected to numerous agronomic traits including yield, seed set, seed longevity, leaf and flower morphology, plant size, lignin content, boron sensitivity, UV-B sensitivity, and biotic stress responses. Related genes in other species are linked to leaf and petal development, seed oil content, drought and salt tolerance, and resistance to Sclerotinia sclerotiorum.
