HAP2A — Medicago truncatula

Summary

MTR_3G061510, also known as HAP2A, MtNF-YA1 or NF-YA9, encodes a CCAAT-binding factor subunit of the NF-YA family and is annotated as a DNA-binding transcriptional co-regulator. In barrel medic, this gene is associated with nitrogen fixation, microgametogenesis, organ growth, photomorphogenesis, auxin anabolism, cytokinin signaling, and the regulation of flowering time, seed dormancy, and the vegetative-to-reproductive phase transition. It has been linked to traits including leaf chlorosis, starch and protein content, male sterility, anther and petal morphology, stem elongation, anthocyanin content, root meristem development, and responses to high temperature, salinity, and abscisic acid. The gene product localises to the nucleus, cytoplasm, plastid, and extracellular space. Studies of related genes in other species connect the NF-YA family to flowering time, seed protein content, drought tolerance, and pathogen resistance.
