APG — Asparagus officinalis

Summary

A4U43_C04F20810 (APG, AoRR3) on asparagus chromosome 4 encodes a protein with GDSL lipolytic enzyme and SGNH hydrolase domains, and is annotated with histidine phosphotransfer kinase, phosphorelay response regulator, red/far-red light photoreceptor, carboxylic ester hydrolase, lipase, acyltransferase, and glycosidase activities. The gene is associated with sex determination, rhythmic processes, circadian regulation of calcium ion oscillation, stem cell population maintenance, photoacclimation, detection of visible light, regulation of cytokinin-mediated signalling, and upregulation of cell division and downregulation of long-day photoperiodism, flowering. It is linked to traits including biomass yield, photosynthetic ability, photoperiod-sensitive flowering time, yield, leaf angle, root phototropism, cadmium concentration, phosphorus uptake, and responses to light, aluminium, nitrate, glyphosate, jasmonic acid, and osmotic stress. Studies of related genes in other species connect the family to cytokinin signalling, red light sensitivity, root and shoot development, and stress tolerance.
