RR3 — Asparagus officinalis

Summary

AoRR3 (RR3) on asparagus chromosome 5 encodes a response regulatory domain-containing protein with histidine phosphotransfer kinase activity, phosphorelay response regulator activity, and red/far-red light photoreceptor activity. It is associated with sex determination, antipodal cell differentiation, embryo sac egg cell differentiation, regulation of cytokinin mediated signalling, upregulation of cell division, stem cell population maintenance, and histidyl-aspartyl phosphorelay. The gene is linked to traits including biomass yield, photosynthetic ability, photoperiod-sensitive flowering time trait, leaf angle, root phototropism response trait, cadmium concentration, glyphosate sensitivity, and yield trait. It localises to the nucleus, plastid, plasmalemma, and plasmodesma. Related genes in other species are associated with cytokinin and red light responses, root development, stress tolerance, and pathogen resistance.
