RR3 — Asparagus officinalis

Summary

AoRR3 (RR3) on asparagus chromosome KV863352 encodes a protein with histidine phosphotransfer kinase, phosphorelay response regulator, and red/far-red light photoreceptor activities, belonging to the ARR-like family with a CheY-like receiver domain. This gene is associated with sex determination, antipodal and egg cell differentiation, cytokinin-mediated signaling regulation, cell division upregulation, stem cell population maintenance, and the red/far-red light signaling pathway. It localizes to the nucleus, plastid, plasmalemma, and plasmodesma. AoRR3 is linked to numerous agronomic traits including yield, biomass, photosynthetic ability, photoperiod-sensitive flowering, root and shoot morphology, leaf angle and curling, tuber size, and responses to glyphosate, nitrate, aluminum, UV-B, jasmonic acid, and osmotic stress. It is also connected to cytokinin signal transduction, root hydrotropism, drought tolerance, and pathogen resistance.
