HAM1 — Medicago truncatula

Summary

MTR_4G026485, designated MtHAM1, encodes a GRAS family transcription factor with DNA-binding and protein homodimerization activity. It is associated with hyphopodium formation, vision, stomium development, posttranscriptional regulation of gene expression, axillary shoot meristem initiation, strigolactone anabolism, procambium histogenesis, cutin anabolism, response to nutrient, upregulation of stem cell maintenance, pigmentation, maintenance of shoot apical meristem identity, regulation of protein breakdown, root hair tip growth, lipogenesis, stem cell population maintenance, phosphate ion detection, and regulation of seed dormancy process. Associations with shoot branching, primary root elongation, chlorophyll accumulation, floral organ size, inflorescence development, anther and stamen morphology, plant male sterility, gibberellic acid and cytokinin sensitivity, auxin content, and vegetative growth time have been noted. Related genes in other species link the family to shoot and root meristem regulation, stem cell maintenance, and organ regeneration.
