Gene Details:

Functional Descriptions:

  • Northern blot and immunoblot analyses revealed that ALDH2b was constitutively present in all the organs examined, whereas ALDH2a was expressed in leaves of dark-grown seedlings and panicles.
  • We suggest that the rice ALDH2a and ALDH2b genes are orthologues of maize mitochondrial ALDH genes, rf2b and rf2a, respectively.
  • Organ-specific expressions and chromosomal locations of two mitochondrial aldehyde dehydrogenase genes from rice (Oryza sativa L.), ALDH2a and ALDH2b.
  • The mitochondrial aldehyde dehydrogenase OsALDH2b negatively regulates tapetum degeneration in rice.
  • These results demonstrate that OsALDH2b negatively regulates tapetal PCD and is required for male reproductive development, providing insights into the regulation of tapetum development in plants.
  • Loss of function of OsALDH2B1 greatly enhanced resistance to broad-spectrum pathogens, including fungal blast, bacterial leaf blight, and leaf streak, but caused severe phenotypic changes such as male sterility and reduced plant size, grain size, and number.
  • OsALDH2B1 has its primary function as an aldehyde dehydrogenase and a moonlight function as a transcriptional regulator.
