IPK — Beta vulgaris subsp. vulgaris

Summary

BvIPK (BVRB_6G153170) on sugar beet chromosome 6 encodes a protein with isopentenyl phosphate kinase activity, belonging to the Asp/Glu/Uridylate_kinase domain family. The gene is directly annotated to terpenoid anabolism and localised to the cytosol and cytoplasm. In sugar beet, BvIPK is associated with root yield, photosynthetic rate, and plant height. Studies of related genes in other species link the IPK family to terpenoid production, decreased sterol content and β-caryophyllene emission, as well as traits including root branching, root length, water use efficiency, transpiration rate, stomatal resistance, photochemical quenching, drought tolerance, and protein content.
