Abstract:

The recent advances in heme oxygenase (HO) catalytic metabolism, structural characteristics, genetic mutants, and physiological functions during plant phytochrome chromophore synthesis, root morphogenesis as well as participating in plant responses against abiotic stresses and corresponding signaling transduction were reviewed. Meanwhile, recent progress in the regulation of plant HO gene expression conferred by many stimuli and phytohormones, such as UV-B and salt stress, auxin and abscisic acid (ABA) was also summarized preliminarily.

Key words: plant heme oxygenase; structure; function; signal transduction; carbon monoxide
