PLP — Medicago truncatula

Summary

MTR_5G038420, designated MtPLP, encodes a protein with photoreceptor activity, blue light photoreceptor activity, and protein serine/threonine kinase activity, and contains PAS and PAC domains. It is associated with GDP-galactose:mannose-1-phosphate guanylyltransferase activity and GDP-D-glucose phosphorylase activity. The gene is linked to ascorbate metabolism, abscission, brassinosteroid homeostasis, defense response by callose deposition, blue light signaling, circadian rhythm, and responses to ozone, jasmonic acid, and heat. Associations include traits such as biomass yield, flowering time, seed viability, anthocyanin content, leaf senescence, disease tolerance, and salt tolerance. Phenotypic connections include vitamin C biosynthesis, drought tolerance, aphid resistance, and pollen fertility. The protein localizes to the cytosol, nucleus, and plasma membrane. Related genes in other species are linked to ascorbate biosynthesis and flowering time.
