Cloned(Commentary)

Cloned (Comment) Organism
gene sox, quantitative real-time PCRenzyme expression analysis, recombinant overexpression in Arabidopsis thaliana mutant strain atso-1 by T-DNA insertion, line CS_346908. Enzyme Recombinant expression in maize inbred line Zheng58 immature embryos via transfection with Agrobacterium tumefaciens strain LBA4404 using the 5S promoter of Cauliflower mosaic virus Zea mays

Protein Variants

Protein Variants Comment Organism
additional information unlike the null mutant atso-1, ZmSO-overexpressing transgenic Arabidopsis plants are tolerant to SO2 stress and can effectively rescue the susceptible phenotype of atso-1 Zea mays

General Information

General Information Comment Organism
malfunction silencing of ZmSO could lead to seed germination delay upon sulfite exposure, but not under normal conditions Zea mays
physiological function sulfite oxidase plays an important role in sulfite metabolism by catalyzing the physiologically vital oxidation of sulfite to sulfate in plants. Sulfite oxidase is essential for timely germination of maize seeds upon sulfite exposure, seed germination is inhibited by sulfite. Embryonic sulfite oxidase might be essential for timely seed germination upon sulfite exposure in maize Zea mays
