physiological function | BrHO1 may play an important role in abiotic stress tolerance of Chinese cabbage. Heme oxygenase is a regulatory enzyme that cleaves heme to biliverdin IXalpha, with the concomitant release of carbon monoxide and the production of free Fe2+ | Brassica rapa subsp. pekinensis |
