CCD7 — Oryza sativa Japonica
Summary
OS04G0550600 (CCD7, also known as HTD1, OsMAX3) encodes a carotenoid oxygenase family protein with 9-cis-beta-carotene 9',10'-cleavage oxygenase activity (EC 1.13.11.68). The enzyme is localised to the chloroplast thylakoid membrane and stroma. In rice, CCD7 is associated with strigolactone anabolism, auxin transport, shoot development, secondary thickening, seed maturation, and response to herbicide. It has been linked to plant architecture, tillering capacity, panicle number, grain number and size, seed setting rate, seed shattering, spikelet fertility, plant height, and grain yield. Associations also include leaf shape, root system architecture, flowering time, nitrogen deficiency response, and somatic embryogenesis. Related genes in other species link the family to strigolactone biosynthesis, lateral branching, vascular tissue development, and elevated IAA and ABA levels.
